| Can't spawn enoguh Spark executors (limited to 8?) Posted: 15 May 2021 08:15 AM PDT For a Tensorflow Script I need precisely 12 Spark executors to run simultaneously on my three-node cluster (each 32/64-cores, 4 graphics-cards). I cannot find resources on the internet that really help me. There is spark.executor.instances, and together with spark.resource.gpu.amount I can change the needed slots somewhat, but for me it's a trial and error approach, and also I am getting nowhere. When I set 2 GPUs per executor, TF asks for 6 slots. But then Spark does only spawn 4 executors (two on one node, one on each other node). When I set 1 GPU per executor, TF asks for 12. Then Spark spawns up to eight executors (three on two nodes, two on the other one), but it still doesn't work. All this is independent from my spark.executor.instances setting. I can limit my executors with this, but if I set it to like 24 or something like this, it still does only spawn 4 or 8 executors respectively. From my description it becomes clear that I do not really know what to do. The official documentation gives somewhat of a impression of what the config-keys are meant to do, but it doesn't change anything for me. Does someone have valuable resources on how to achieve my goal? I'll be happy to provide more infos if needed. Thanks in advance!  |

| Unstructured invoice data frame into multiple columns Posted: 15 May 2021 08:15 AM PDT I am new to this forum and I need some help to tidy this data frame into 5 different columns: 'invoice no', 'name', 'address', 'zip', 'extra' I encountered a few problems as there are no patterns at all. These are 'invoice no' issued (CM3398, G113524, etc) it is stuck together with the 'name' Sometimes the 'zip' is together with the 'address' and there are 3 and sometimes 4 rows after the 'invoice no'.

| No device driver found while installing windows Posted: 15 May 2021 08:15 AM PDT Here is the situation, I was trying to install Windows 10 on my PC. I have cleaned the hard disk (including the C drive which contained my Windows OS) and started installation with my bootable usb. I was getting an error called "No device driver found". I tried changing usb stick to different ports but the problem still exists. I have tried the same usb stick for my laptop to check whether the Windows installation is corrupted or not, and it was working perfectly fine. After that I searched and found that by installing intel rapid storage drivers might fix the issue but I was not able to install it because my bootable usb is not visible in the browse section. It only shows C drive (which is empty), a disk drive and a boot drive (but it does not contain those files). Later, I thought of using DVD for the device drivers and tried installing but it gave an error that either files are not correct or they are not present in installation media. I can even burn Windows iso on DVD as the size of iso file is larger than my DVD. I tried diskpart list disk # But this shows only my harddrive and not my usb stick, even if I connect multiple usb stick. I have 6 different ports available but none of them worked in detecting it. clean create partition primary format fs=ntfs exit
I also tried installing Windows 7 but the same issue persist. In short, I am not able to install any of the Windows OS. Can anyone please help. THANK YOU!  |
| reset input text by clicking outside vue Posted: 15 May 2021 08:15 AM PDT I have an autocomplete field. If i put any text and it matches the result set then it will populate the dropdown result. If it doesn't match anything then by clicking outside it will reset the input field forcefully. So, for this approach i have created the vue click outside directive import Vue from 'vue'; const nodeList = []; const ctx = '@@clickoutsideContext'; let startClick; const counter = 0; const isServer = Vue.prototype.$isServer; /** * added this on event function for direct dom manipulation */ const onEvent = (function() { if (!isServer && document.addEventListener) { return function(element, event, handler) { if (element && event && handler) { element.addEventListener(event, handler, false); } }; } return function(element, event, handler) { if (element && event && handler) { element.attachEvent(`on${event}`, handler); } }; })(); !isServer && onEvent(document, 'mousedown', e => { startClick = e; }); !isServer && onEvent(document, 'mouseup', e => { nodeList.forEach(node => node[ctx].documentHandler(e, startClick)); }); // setting up mouse events function createDocumentHandler(el, binding, vnode) { return function(mouseup = {}, mousedown = {}) { if ( !vnode || !vnode.context || !mouseup.target || !mousedown.target || el.contains(mouseup.target) || el.contains(mousedown.target) || el === mouseup.target || (vnode.context.popperElm && (vnode.context.popperElm.contains(mouseup.target) || vnode.context.popperElm.contains(mousedown.target))) ) return; if ( binding.expression && el[ctx].methodName && vnode.context[el[ctx].methodName] ) { vnode.context[el[ctx].methodName](); } else { el[ctx].bindingFn && el[ctx].bindingFn(); } }; } /** * v-clickoutside * @desc Only trigger when click outside * @example * ```vue * <div v-element-clickoutside="handleClose"> * ``` */ export default { bind(el, binding, vnode) { nodeList.push(el); const id = counter + 1; el[ctx] = { id, documentHandler: createDocumentHandler(el, binding, vnode), methodName: binding.expression, bindingFn: binding.value }; }, update(el, binding, vnode) { el[ctx].documentHandler = createDocumentHandler(el, binding, vnode); el[ctx].methodName = binding.expression; el[ctx].bindingFn = binding.value; }, unbind(el) { const len = nodeList.length; for (let i = 0; i < len; i += 1) { if (nodeList[i][ctx].id === el[ctx].id) { nodeList.splice(i, 1); break; } } delete el[ctx]; } };
Autocomplete field is working fine. I am not able to understand how this directive will be used to reset input field. Any suggestions or examples will be helpful to understand.  |
| Logic wrong in custom loop on permissions authorization filter Posted: 15 May 2021 08:15 AM PDT Im getting false positives here basically what I want to happen is. It should only return an error if say for example the user does not have permission to do Create but at present its returning an error all the time when he has that permissions. | User | Permission | Active | | 12 | Create | True | | 12 | Update | False | | 12 | Delete | True | First Example [HasPermission("Create");
Should Return True it does but false positive, because read update and delete are not present. Second Example [HasPermission("Create,Update");
Should return false but is but is also returning that read and delete is not present when am only asking for create and update Code: string[] permissionValues = permission.Split(","); Dictionary<string, bool> dict = new Dictionary<string, bool>(); foreach (var item in permissionValues) { var permissions = db.AppWarehouseUserPermmissions.Any(w => w.Name == item && w.Controller == controllerName && w.isAcitve == true); dict.Add(item, permissions); } foreach (var item in dict) { if (item.Key == "Create" || item.Key == "Read" || item.Key == "Update" || item.Key == "Delete" && item.Value == true) { isAuthorised = true; } if (item.Key == "Create" || item.Key == "Read" || item.Key=="Update" || item.Key=="Delete" && item.Value==false) { _customError.Add(new CutomError() { Message = $"User has no {item.Key} permissions", ErrorCode = item.Key }); } } return isAuthorised;

| How to launch multiple animated objects, each with a delay (Jetpack Compose)? Posted: 15 May 2021 08:15 AM PDT Currently, I have one tile travelling from bottom to top in an infinite loop. This is the code I am using: val infiniteTransition = rememberInfiniteTransition() val durationMillis = remember { mutableStateOf(5000) } val delayMillis = remember { mutableStateOf(0) } val positionState = infiniteTransition.animateFloat( initialValue = 0f, targetValue = 1f, animationSpec = infiniteRepeatable( animation = tween( durationMillis = durationMillis.value, delayMillis = delayMillis.value, easing = LinearEasing ) ) )
I am trying to launch several of these tiles in the same direction at various intervals, indefinitely. I don't want to wait until one has reached the top to launch another and I want each tile to reach the top before disappearing. So this is the code I am using to increase the delay for each new tile: } else if (index >= 7) { placeable.placeRelative( constraints.maxWidth - tileSize, yPosition - placeable.height * 7 + verticalAnimationPositioning, 1f ) delayMillis.value += 1000 }
And verticalAnimationPositioning is this: val verticalAnimationPositioning = (constraints.maxHeight - (constraints.maxHeight * positionState.value)).toInt()
This does nothing. What happens is that all my tiles travel at the same time and disappear as soon as the first one reaches the top. Do you have any idea how I can achieve having the tiles travel independently at intervals?  |

| Why does switching order of OR statement fix TypeError: '<=' not supported between 'str' and 'int'? Posted: 15 May 2021 08:15 AM PDT I am doing some basic data validation, and I'm confused. I have the following function: def is_int_gt2(num): if num <= 2 or type(num) != int: return False else: return True
When I call is_int_gt2(-1) I get False. And when I call is_int_gt2(5) I get True. So far so good. But if I call is_int_gt2('a'), I get TypeError: '<=' not supported between instances of 'str' and 'int' What confuses me, however is that when I switch the order of the conditions in the or statement, the function works perfectly!: def is_int_gt2(num): if type(num) != int or num <= 2: return False else: return True
So now I have a working function, but I don't know why. Why does switching the order of the condition fix the function? Thank you.  |

There are many cards when I click on one of the cards I want to navigate to another page. How Can I achieve this?

| Laravel5.3 maatwebsite/excel Read value from excel & insert into database Posted: 15 May 2021 08:15 AM PDT Here is my Excel data sheet type: 
Here is My Table Schema: 
Here is my method to import data: public function saveActivationInfoExcel(Request $request) { if($request->hasFile('import_file')){ $path = $request->file('import_file')->getRealPath(); $data = Excel::load($path, function($reader) {})->get(); if(!empty($data) && $data->count()){ foreach ($data->toArray() as $key => $value) { if(!empty($value)){ foreach ($value as $v) { $insert[] = [ 'mobile_no' =>$v['mobile_no'], 'model' => $v['model'], 'serial_1' => $v['serial_1'], 'serial_2' => $v['serial_2'], 'activation_date' => $v['activation_date'], ]; } } } dd($insert); if(!empty($insert)){ //ProductActivationInfo::insert($insert); return back()->with('success','Insert Record successfully.'); } } } return back()->with('error','Please Check your file, Something is wrong there.'); }
Now my problem is, when I try to import data I got this dd($insert) error Illegal string offset 'mobile_no' 'serial_1' => '3.5194508009307E+14', 'serial_2' => '3.5194508009307E+14', 'activation_date' => object(Carbon), null)
have a look both serial_1 & serial_2 showing different value rather then actual excel value. also activation_date value is null. would appreciate your valuable suggestion to solve this regarding reading data using "maatwebsite/excel" laravel library.  |
| Why on testing a Riak node 'riak-admin test' fails but 'curl -v http://127.0.0.1/8098/types/default/props' succeeds Posted: 15 May 2021 08:14 AM PDT I am setting up a riak cluster of five physical nodes. The other four are fine with all tests except one fails the admin-riak test. The cluster state on several riak-admin commands is shown below do-admin@DBNode1:~$ sudo riak-admin member-status =============== Membership ============================ Status Ring Pending Node ------------------------------------------------------------------------------- valid 20.3% -- 'riak@dbnode1.do.ug' valid 20.3% -- 'riak@dbnode2.do.ug' valid 20.3% -- 'riak@dbnode3.do.ug' valid 20.3% -- 'riak@dbnode4.do.ug' valid 18.8% -- 'riak@dbnode5.do.ug' ------------------------------------------------------------------------------- Valid:5 / Leaving:0 / Exiting:0 / Joining:0 / Down:0 dot-admin@DBNode1:~$ sudo riak-admin ring-status ================================== Claimant =================================== Claimant: 'riak@dbnode2.do.ug' Status: up Ring Ready: true ============================== Ownership Handoff ============================== No pending changes. ============================== Unreachable Nodes ============================== All nodes are up and reachable do-admin@DBNode1:~$ sudo riak-admin cluster status ---- Cluster Status ---- Ring ready: true +------------------------+------+-------+-----+-------+ | node |status| avail |ring |pending| +------------------------+------+-------+-----+-------+ | riak@dbnode1.do.ug |valid | up | 20.3| -- | | (C) riak@dbnode2.do.ug |valid | up | 20.3| -- | | riak@dbnode3.do.ug |valid | up | 20.3| -- | | riak@dbnode4.do.ug |valid | up | 20.3| -- | | riak@dbnode5.do.ug |valid | up | 18.8| -- | +------------------------+------+-------+-----+-------+ Key: (C) = Claimant; availability marked with '!' is unexpected do-admin@DBNode1:~$ curl -v http://dbnode1.dot.ug:8098/types/default/props * Hostname was NOT found in DNS cache * Trying 192.168.172.38... * Connected to dbnode1.dot.ug (192.168.172.38) port 8098 (#0) > GET /types/default/props HTTP/1.1 > User-Agent: curl/7.35.0 > Host: dbnode1.dotshule.ug:8098 > Accept: */* > < HTTP/1.1 200 OK < Vary: Accept-Encoding * Server MochiWeb/1.1 WebMachine/1.10.5 (jokes are better explained) is not blacklisted < Server: MochiWeb/1.1 WebMachine/1.10.5 (jokes are better explained) < Date: Sat, 17 Jan 2015 21:05:22 GMT < Content-Type: application/json < Content-Length: 428 < * Connection #0 to host dbnode1.dotshule.ug left intact {"props":{"allow_mult":false,"basic_quorum":false,"big_vclock":50,"chash_keyfun":{"mod":"riak_core_util","fun":"chash_std_keyfun"},"dvv_enabled":false,"dw":"quorum","last_write_wins":false,"linkfun":{"mod":"riak_kv_wm_link_walker","fun":"mapreduce_linkfun"},"n_val":3,"notfound_ok":true,"old_vclock":86400,"postcommit":[],"pr":0,"precommit":[],"pw":0,"r":"quorum","rw":"quorum","small_vclock":50,"w":"quorum","young_vclock":20}} dot-admin@DBNode1:~$ sudo riak-admin test Node 'riak@dbnode1.dot.ug ' is not reachable from 'riak_test@dbnode1.dot.ug'.
After all those tests with the same results on all nodes except for the **riak-admin test ** which is like this on all other nodes. For node three dot-admin@DBNode3:~$ sudo riak-admin test Successfully completed 1 read/write cycle to 'riak@dbnode3.dotshule.ug'
My doubt is whether this cluster is ready to used to store data because on this Basho website resource, they say you can use any of the methods to test whether the node is ready. They do not say that the node is still fine if one method success and the other fails. So I am stuck on whether to go ahead to use the cluster or not. Surprisingly this node has succeeded on all operations to join it in the cluster!! I have tried creating this node from scratch again but that has not helped! For any help, I will be glad.  |
