How do I print scatter plots in a pandas column? Posted: 20 May 2021 08:51 AM PDT I created a pandas dataframe using the below code. (See the extra code and plt.show() which is there to create a new plot every time or else we get one plot with all of them in the same plot) %matplotlib inline pd.DataFrame( np.array([[ col, plt.scatter(data[col], data['SalePrice']) and plt.show()] for col in data.columns]), columns=['Feature', 'Scatter Plot'] ) But what I get is this And at the end of the dataframe, I get all the scatter plots separately. What I want is, for those graphs to get printed inline, inside the columns, just like the other values.

ValueError: Found input variables with inconsistent numbers of samples: [4, 3] Posted: 20 May 2021 08:51 AM PDT I'm looking to figure out why this code is not working. The error code I'm getting is ValueError: Found input variables with inconsistent numbers of samples: [4, 3] and I'm just not really understanding why import numpy as np import matplotlib import matplotlib.pyplot as plt from sklearn import svm from sklearn.model_selection import train_test_split L1=[1,2,3,4] L2=[5,6,7] trainX, testX, trainY,testY = train_test_split(L1,L2,test_size = 0.4, random_state = 12345678) trainX.shape,testX.shape,trainY.shape,testY.shape def poly_grid_search(L1, L2): for list1 in L1: for list2 in L2: print(list1, list2) print(list1*list2) psvm = svm.SVC(kernel='poly', degree=list1, C= 2) psvm = svm.SVC(kernel='poly', degree=list2, C= 2) psvm.fit(trainX,trainY) print("polynomial kernel degree = {}, acurracy rate {}".format(L2, psvm.score(testX,testY)))

Vue 1.x ignoredElements equivalent Posted: 20 May 2021 08:51 AM PDT I'm tryin to integrate a stencil.js component with an existing Vue 1.x project. I've done the same thing in a Vue 2.x project and ingoredElements config. Is there an equivalent to such thing in Vue 1.x or is the integration done differently? As of now, I'm unable to see my component and the following warning is outputted to the console. Unknown custom element: <test-component> - did you register the component correctly? For recursive components, make sure to provide the "name" option. Any help is appreciated :)

Flutter: Periodically calling list.add() inside initState() causes build() to run but the updated List isn't shown on screen Posted: 20 May 2021 08:51 AM PDT On the screen I expect to see an ever growing list: 0 1 2 ... but it's just black. If I hit CTRL+S in Android Studio all of a sudden the whole list is finally shown. import 'dart:async'; import 'package:flutter/material.dart'; void main() => runApp(MyApp()); class MyApp extends StatefulWidget { @override _MyAppState createState() => _MyAppState(); } class _MyAppState extends State<MyApp> { List<Widget> list = []; @override Widget build(BuildContext context) { print('${list.length}'); return MaterialApp( home: ListView( children: list, ), ); } @override void initState() { super.initState(); new Timer.periodic(const Duration(seconds: 1), (timer) { setState(() { list.add(Text('${list.length}', key: Key(list.length.toString()))); }); }); } } At first I thought it was because I wasn't setting key property, but I added that and still nothing. I know the build() property is being triggered every second because I see the print() statement showing the numbers in the debug Run tab output. What am I missing here? It's got to be something simple!

Hi, I have a project in which I need to display the binary search tree, this is my algorithm, how can I display the output in a tkinter widget?

Given these type declarations in OCaml for a stream type, how to I write a flatten function? Posted: 20 May 2021 08:51 AM PDT exception Empty_list type 'a stream = Stream of 'a * (unit -> 'a stream) | Nil let shead s = match s with | Stream (a, _) -> a | Nil -> raise Empty_list let stail s = match s with | Stream (_, s) -> s () | Nil -> raise Empty_list The flatten function would take an arbitrarily nested set of streams and produce a completely flattened version that's a result of an inorder traversal of the nesting structure and contains only the leaves. This would mean that the result of shead on each member of this new thing would return something that was not a stream.

How to use a git submodule with typescript code in a typescript project Posted: 20 May 2021 08:50 AM PDT I'm working on a VueJS project that uses different colors and some other things depending on a environment variable. These values are contained in another repository I added as a submodule. So the structure in my project is: my-project the-submodule node_modules public src To make this work I included this in the vue.config.js: module.exports = { chainWebpack: config => { config.resolve.alias .set('@theme', path.resolve('the-submodule/' + process.env.VUE_APP_THEME)) }, ... I use it like this, for example in plugins/vuetify.ts: import Vue from 'vue' import Vuetify from 'vuetify/lib/framework' import colors from '@theme/colors' Vue.use(Vuetify) export default new Vuetify({ theme: { themes: { light: { ...colors } } } }) Or in router/index.ts: import texts from '@theme/texts' ... router.afterEach((to) => { Vue.nextTick(() => { document.title = to.meta.title ? `${texts.appName} | ${to.meta.title}` : texts.appName }) }) While this does compile and works, I still get errors during compilation: ERROR in /Users/sme/projects/aedifion-frontend/src/plugins/vuetify.ts(4,20): 4:20 Cannot find module '@theme/colors' or its corresponding type declarations. 2 | import Vue from 'vue' 3 | import Vuetify from 'vuetify/lib/framework' > 4 | import colors from '@theme/colors' | ^ 5 | 6 | Vue.use(Vuetify) 7 | ERROR in /Users/sme/projects/aedifion-frontend/src/router/index.ts(12,19): 12:19 Cannot find module '@theme/texts' or its corresponding type declarations. > 12 | import texts from '@theme/texts' | ^ These are examples of the files in the themes: the-submodule/some-theme/colors.ts: import { Colors } from '../types' export default { accent: '#288946', error: '#e60046', info: '#969196', primary: '#007982', secondary: '#96BE0D', success: '#a0af69', warning: '#fab450' } as Colors the-submodule/some-theme/texts.ts: import { Texts } from '../types' export default { appName: 'MyApp' } as Texts the-submodule/types.ts: export interface Colors { accent: string; error: string; info: string; primary: string; secondary: string; success: string; warning: string; } export interface Texts { appName: string; } I also created different versions of .d.ts files in the-submodule, both for each type or one for alle types. I've tried pretty much everything I could find. How do I get rid of those errors?

How to speed up heatmap? Posted: 20 May 2021 08:50 AM PDT I am trying to plot heatmap with three variables x, y and z, each with vector length of 932826. The time taken with the function below is 28 seconds, with a bin size of 10 on each x and y. I have been using another program where the same plot happens in 6 - 7 seconds. Also, I know that the plot function of that program uses Python in the background So, I was wondering how can I speed up my heatmap plots. Also, is it possible to write the values within each bins of the heatmap ? plt.figure() xi = npr.linspace(min(x), max(x), x_linspace) yi = npr.linspace(min(y), max(y), y_linspace) zi = griddata((x, y), z, (xi[None, :], yi[:, None]), method='linear') plt.figure() plt.pcolormesh(xi, yi, zi) plt.colorbar() plt.xlabel(x_lab) plt.ylabel(y_lab) plt.title(title + 'Mean =' + str(mean(z)) + ' Mean Abs Dev = ' + str(mad(z))) plt.clim(z.min(), z.max()) act_save = savepath + '\\' + plot_name + '_heatmap3.png' mng = plt.get_current_fig_manager() mng.window.state('zoomed') plt.savefig(act_save) plt.close()

Background Video Width and Height CSS Posted: 20 May 2021 08:50 AM PDT i made some website with video on the background, I use 80vh(Vertical Height), but when I press f12, the video background height went smaller, how to fix it? should I change it to px or %?

Ctrl+F underlying implementation Posted: 20 May 2021 08:50 AM PDT Ctrl+F (Cmd+F on MacOS) is the standard keyboard shortcut for finding instances of a string in a document. I've recently been using this command in very large documents, on the order of hundreds of MB of ASCII characters. In the default text editor on Ubuntu, I've noticed that it often takes quite a while for the find to work, and sometimes it seems to simply fail. This makes me wonder about what's going on under the hood. How optimized is the algorithm that runs when I do a Ctrl+F? The difference in runtime between a naive character-by-character search and something like the BLAST algorithm from computational genomics can be enormous with long query strings in long files. Also, does Ctrl+F call the same underlying code when I do it in Text Editor as in VSCode as in Chrome, or do different applications use different implementations?

c++ returning object from a function Posted: 20 May 2021 08:51 AM PDT The code below shows a class representing complex numbers. My interest is in understanding the operator+ function. As I understand Complex res should be allocated on the frame of the function operator+. Is it correct to return this object to the caller? By the time this function returns the frame would have been popped but res would continue to be used by the caller. Unless there is more to this than meets the eye, like the actual return res may actually be copying the object from current frame to the caller's frame. Another possibility can be that the code inside the operator+ function may be inlined on the call site in main? From my limited understanding of the language, functions declared within the class are by default inlined on the call site. Any help will be appreciated. #include<iostream> using namespace std; class Complex { private: int real, imag; public: Complex(int r = 0, int i =0) {real = r; imag = i;} Complex operator+(Complex const &obj) { Complex res; res.real = real + obj.real; res.imag = imag + obj.imag; return res; } void print() { cout << real << " + i" << imag << endl; } }; int main() { Complex c1(10, 5), c2(2, 4); Complex c3 = c1 + c2; c3.print(); }

Why is spark dataframe repartition faster than coalesce when reducing number of partitions? Posted: 20 May 2021 08:51 AM PDT I have a df with 100 partitions, and before saving to HDFS as .parquet I want to reduce the number of partitions because the parquet files would be too small (<1MB). I've added coalesce before writing: df.coalesce(3).write.mode("append").parquet(OUTPUT_LOC) It works but slows down the process from 2-3s per file to 10-20s per file. When I try repartition: df.repartition(3).write.mode("append").parquet(OUTPUT_LOC) The process does not slow down at all, 2-3s per file. Why? Shouldn't coalesce always be faster when reducing the number of partitions because it avoids a full shuffle? Background: I'm importing files from local storage to spark cluster and saving the resulting dataframes as a parquet file. Each file is approx 100-200MB. Files are located on the "spark-driver" machine, I'm running spark-submit in client deploy mode. I'm reading files one by one in driver: data = read_lines(file_name) rdd = sc.parallelize(data,100) rdd2 = rdd.flatMap(lambda j: myfunc(j)) df = rdd2.toDF(mySchema) df.repartition(3).write.mode("append").parquet(OUTPUT_LOC) Spark version is 3.1.1 Spark/HDFS cluster has 5 workers with 8CPU,32GB RAM Each executor has 4cores and 15GB RAM, that makes 10 executors total.

JFreeChart: Add labels for datapoints in TimeSeriesChart Posted: 20 May 2021 08:50 AM PDT I am new to Java and JFreeChart (Servlet in Web application). I created a Time Series Chart that displays Progress (Y Axis) on weekly (X Axis) basis. I am including my code snippet below. I want to add labels to datapoints. As the datapoints are large in number (weekly data for 2 years), displaying label for every datapoint makes the graph look congested and the labels are not readable because of overlap. How to skip labels for certain datapoints? Say, labels needs to be displayed for first week data of every month. How to tilt the labels by certain angle (say 30 degrees) so that they do not overlap? Any working code snippet would be highly helpful to me. JFreeChart chart = ChartFactory.createTimeSeriesChart("Progress", "On Week", "Progress", dataset); XYPlot plot = (XYPlot) chart.getPlot(); plot.setDomainGridlinesVisible(true); plot.setRangeGridlinesVisible(true); DateAxis dateAxis = (DateAxis) plot.getDomainAxis(); dateAxis.setVerticalTickLabels(true); XYLineAndShapeRenderer renderer = (XYLineAndShapeRenderer)plot.getRenderer(); renderer.setSeriesShapesVisible(0, true); renderer.setSeriesPaint(0, Color.GREEN); renderer.setBaseItemLabelsVisible(true); EDIT: My graph looks like this. I highlighted the portion where the labels overlap.

Why isn't @JmsListener in ActiveMQ working? Posted: 20 May 2021 08:50 AM PDT First, I made a test project to learn how to work with ActiveMQ. Everything worked there. But when I did the same with an already made application on Spring + security + JAAS then everything stopped working, and apparently the JmsListener class is not working. I sent messages to this queue via ActiveMQ admin but didn't work.

How to query certain jsonb fields using Npgsql Posted: 20 May 2021 08:50 AM PDT I'm trying to map a query like this using a jsonb column in Postgres into a C# object: select item_object->'thing' FROM "Table", jsonb_array_elements("JsonColumn") with ordinality arr(item_object); (Where in this case JsonColumn contains an array of JSON objects, each of which has a 'thing' field.) I see that using JsonDocument or POCO can be used to map these Json functions in the WHERE clause, but in my case I'm trying to restrict how much of the document gets sent back to reduce the size and amount of deserialization needs to happen. Is there any way to do this in C# or do I need to build customized queries? Thanks! -- Edit -- For example, can we query specific jsonb fields using this sort of query in C# DataContext.Table.Select(t => new { t.JsonColumn.thing }); To dig through the json and only return the 'thing' field instead of the entire json blob.

DAX SUM DISTINCT values by groups Posted: 20 May 2021 08:51 AM PDT I'm new to PBI/DAX. I have a table called Opp Recs with a few columns: Group1, NumEmp, OppRec, AcctNum. I want to sum the NumEmp column if Group1 equals "Corp Employees" but only for unique AcctNum. I used this formula but realized NumEmp was double counted for dup AcctNums: **Corp # Emps = CALCULATE(SUM('Opp Recs'[NumEmp]), 'Opp Recs'[Group1] = "Corp Employees")** How can I sum NumEmp correctly? Sample Data: Group1    NumEmp    OppNum    AcctNum Corp Employees    450  000030689  A0000123 Corp Employees    450  000030624  A0000123 Corp Employees    150  000030118  A0000662 Small Bus Emp      5  000030637 A0000737 Small Bus Emp      37    000030738  A0000755 Corp Employees    100    000030639   A0000784 Corp Employees    100    000030616   A0000784

Dependency Injection not working for IConfiguration C#.Net Core Posted: 20 May 2021 08:51 AM PDT I have injected IConfiguration using following code: public class InjectorConfig { /// <summary> /// configuration for DI /// </summary> /// <param name="services"></param> /// <param name="configuration"></param> public static void Init(IServiceCollection services, IConfiguration configuration) { services.AddSingleton<IConfiguration>(provider => configuration); services.AddSingleton<AppSettingUtil>(); } } while using this in my class called AppSettingUtil I am getting null pointer exception on IConfiguration object.

Code128 Barcode in Adobe Acrobat Form Text Field Posted: 20 May 2021 08:51 AM PDT We have a PDF form where you fill out product options then it converts those options into a single text field "Lot Number" then finally a field, "Lot Number Barcode", takes the lot number and converts it to a barcode. For some reason this is not working. I know almost nothing about barcode integration but I am a programmer and just looking for some guidance on this topic. The "Lot Number Barcode" field uses under properties Calculate->Custom Calculation Script this code. So like I said above it's taking the "Lot Number" field and converting to a string which I believe then the font uses to generate the correct barcode or that is the idea. event.value = this.getField("Lot No").valueAsString; Here is a link to the actual PDF I was given from the client: https://ufile.io/ihh87 This is what I have found out on this topic but obviously still missing pieces to the puzzle and hope someone can give me the exact steps needed to get this working in Acrobat Pro. I need an embeddable CODE 128 font? I found this font set but costs $159 is there a free version that I could use and have it still work? https://www.idautomation.com/barcode-fonts/code-128/ Javascript - I need to add custom Javascript code to the Actions properties of the "Lot Number Barcode" text field but I don't know which code needs to be implemented and looking for a resource on this to better explain the process. Font height and font size - If I get the previous 2 steps working I still need to be concerned with setting the PDF text field to an exact font size and height otherwise the barcode scanner could error out. Is this true? Currently the PDF text field font size is set to "Auto"

Flutter.h not found error Posted: 20 May 2021 08:51 AM PDT I've lost the ability to build Flutter applications for iOS since a few days back. I updated my iPad to 11.4 which forced me to update xCode to 9.4 and I think there was a new release of Flutter thrown in the mix too. In my infinite wisdom I updated them all and now can't test my projects any more. With deadlines approaching quickly I am looking for advice on how to get moving again.

Python: modul not found after Anaconda installation Posted: 20 May 2021 08:50 AM PDT I've successfully installed Python 2.7 and Anaconda but when i try to import a library i get always this error: >>> import scipy Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named scipy I've set up the PYTHONHOME to C:\Python27 and PYTHONPATH to C:\Python27\Lib. EDIT : content of PATH In my $PATH variable i have C:\Users\Mattia\Anaconda2, C:\Users\Mattia\Anaconda2\Scripts and C:\Users\Mattia\Anaconda2\Library\bin. Do i have to set any other env veriables?

Name attribute in @Entity and @Table Posted: 20 May 2021 08:50 AM PDT I have a doubt, because name attribute is there in both @Entity and @Table For example, I'm allowed to have same value for name attribute @Entity(name = "someThing") @Table(name = "someThing") and I can have different names as well for same class @Entity(name = "someThing") @Table(name = "otherThing") Can anybody tell me what is the difference between these two and why we have same attribute in both?
