I got pickle file with vectors for images using mmdetection class here Link but the result gave me the vectors only without the image_id for each vector .. so i tried to change some lines as below if isinstance(result[0], tuple): result = [(bbox_results, encode_mask_results(mask_results)) for bbox_results, mask_results in result] data1.append(img_meta['ori_filename']) images= f=open('file.txt','w') for i in data1: i=re.sub('.jpg', '', i) i=i.replace("COCO_val2014_", '') f.write(i+os.linesep) images.append(i) d={} d= dict(zip(images, result)) with open('filename.pkl','wb') as f1: pickle.dump(d, f1) results.extend(d) for _ in range(batch_size): prog_bar.update() return results
but the number of vectors are changed and gave me the only image_id the original one was [[array([3.43202576e+02, 2.43713760e+01, 4.96343414e+02, 3.32774170e+02, 8.81948233e-01], [4.71771484e+02, 1.72076767e+02
and what i got is {'000000391895': [array([3.48745178e+02, 1.64561447e+02, 4.19237061e+02, 3.62992340e+02, 9.35315311e-01], dtype=float32),array([[2.54942383e+02, …
what i need is {'000000391895': [array([3.48745178e+02, 1.64561447e+02, 4.19237061e+02, 3.62992340e+02, 9.35315311e-01], dtype=float32),'000000125498'array([2.54942383e+02, …

I am trying to build a dynamic chart generator using Lavacharts where a user selects a search parameter and date range (from / to) then a calendar chart is generated displaying the record count values (Y- Axis) on the different dates(X Axis). I wanted to inquire how I may accomplish this using Lavacharts. I have found some information on http://lavacharts.com/#examples but nothing on how data pulled from mysql database can be used in Lavacharts. public function birthChart(Request $request) { $lava = new Lavacharts; $birth = $lava->CalendarChart(); $birth->addDateColumn('Date') ->addNumberColumn('Births'); }

I have created a PowerShell script for Displaying a Form. Looking for automating button click event. The form displays number of Tasks and I am planning to show the list of Tasks on the form. After running each task, dynamically update status of each task on the form. I have created a TaskList funtion that runs after ButtonClick. The code for running each task and dynamically updating status of each task is mentioned in this function. Only thing I am stuck at is to automate the button click event as soon as the form is launched. Then I can make the Button invisible. Can anybody please suggest the way to automate button click or any other method to call the TaskList funtion

I'm trying to create a function that checks if any rows in a pandas DataFrame meet a list of conditions. If any are met, I want it to return a 1 to a newly created column called "Error", otherwise, it returns 0. I created this function to apply the conditions, but it's not working: def validation_error(row): """ Conditions: a. Service Type (col C) == 'NF' and Demonstration Type (col D) in ('COST', 'PERDIEM') AND i. Validation category (col G) == 'Missing required data' and Fail column (col L) in (212.1, 212.2) b. Service Type (col C) == 'OP' and Demonstration Type (col D) == 'COST' AND i. (Validation category (col G) == 'Missing required data' and Fail column (col L) == 205 OR ii. Validation check (col H) == 'Data validations: Check selected fields for invalid negative values' and Fail column (col L) == 205) c. Issue severity (col I) == 'Critical - automatic rejection' """ # create list of conditions to apply to extract rows condition1 = (stacked_df['Issue severity'].str.lower().str.startswith('critical')) if row['Service type'] == 'OP': condition2 = ((stacked_df['Demonstration type'] == 'PAYMENT') & (stacked_df['Validation category']=='Missing required data') & (stacked_df['Fail column']=='205')) condition3 = ((stacked_df['Demonstration type'] == 'PAYMENT') & (stacked_df['Validation check'].str.contains('invalid negative values')) & (stacked_df['Fail column']=='205')) elif row['Service type'] == 'NF': condition4 = ((stacked_df['Demonstration type'].isin(['COST','PERDIEM'])) & (stacked_df['Validation category']=='Missing required data') & (stacked_df['Fail column'].isin(['212.1','212.2']))) return condition1 | condition2 | condition3 | condition4
Basically, if the value in the column "Service Type" is equal to OP or NF, I want it to check for the conditions. I also wrote this additional code that creates the new column and creates a new DataFrame with a column that checks if the conditions were met. # Create a column called 'Error' stacked_df['Error'] = stacked_df.apply(validation_error, axis=1) # Create a new dataframe that meet the conditions list filtered_df = stacked_df.loc[stacked_dfs['Error'] == 1]
How would I include the above code within the "validation_error" function? Also, is there a more elegant way for me to apply the function? Thank you.

There are two strings called str1 and str2 and I'm trying to check if str1 can be re-arranged as str2. function scramble(str1, str2) { let arr=; let str1arr = str1.split(""); let str2arr = str2.split(""); let j=0; for(let i=0; i<str1.length; i++){ if(str1arr[i]==str2arr[j]){ arr.push(str1arr[i]); str1arr=str1arr.splice(i,1); j++; i=0; } }if(arr.toString()===str2arr.toString()){ return true; }else{ return false; } }
What I tried basically if str1arr[i]==str2arr[j] it will put the str1arr[i] value on a new array called arr and at the end it will compare str2 and the arr and return True or False. The reason why I used str1arr=str1arr.splice(i,1); to delete the i after the match is because the for loop is reseting it self to check from the "i=0" each time i and j matches and that i would match with other duplicate letters (I hope thats what it does atleast :D). It is an internet question and im not passing the tests. I only pass if the result is FALSE. I want to know what I'm doing and thinking wrong here. Its not performance efficent too so any comment on that would be great too.

I am trying to construct a minheap from an existing vector. My heapifyDown, HeapifyUp, insert, and extractMin functions seem to work fine - For example, I can use them to populate an empty array and retrieve the min. But my buildHeap function seems incorrect. I can't figure out the logical error. class MinHeap{ void heapifyDown(int index,vector<int> &array){ int leftIndex = 2*index + 1; int rightIndex = 2*index + 2; if(rightIndex < array.size()){ int smallerIndex = (array[leftIndex] < array[rightIndex] ? leftIndex : rightIndex); if(array[index] > array[smallerIndex]){ swap(array[index],array[smallerIndex]); heapifyDown(smallerIndex,array); } }else if(leftIndex < array.size()){ if(array[index] > array[leftIndex]){ swap(array[index],array[leftIndex]); heapifyDown(leftIndex,array); } } } void heapifyUp(int index,vector<int> &array){ int parent = (index - 1)/2; if(array[index]<array[parent]){ swap(array[index],array[parent]); heapifyUp(parent,array); } } public: int extractMin(vector<int> &array){ int min = -1; if(array.size()>0){ min = array[0]; array[0] = array[array.size()-1]; array.pop_back(); if(array.size()>0) heapifyDown(0,array); } return min; } void insert(int value,vector<int> &array){ array.push_back(value); heapifyUp((int)array.size()-1,array); } void buildHeap(vector<int> &array){ int startIndex = (int)array.size()/2 -1; for(int i=startIndex; i >=0; i--){ heapifyDown(i,array); } } };
What is logically incorrect about my buildHeap function ? The objective of the buildHeap function is to take an existing vector of numbers and convert it into a minheap. The problem is that the buildHeap function does not convert the vector into a valid heap, and instead fills it with incorrect numbers. An example of max-Heapify is here: https://www.tutorialspoint.com/design_and_analysis_of_algorithms/design_and_analysis_of_algorithms_heapify_method.htm I am trying to do the same, but with a minHeap instead of a maxHeap.

I have asked this question .exec callback using returns is returning undefined, but console.log do have item in it The answer does work, but it throws .exec away, I have been trying to re-implement it using .exec, however when I console.log something inside the .exec, it does print. The reason I have been trying to use the .exec way is that a lot of StackOverflow questions use a lot .exec and I think ".exec" will be faster? When I return it, it returns undefined. What is the cause and how can I solve it while keeping the .exec let user = await User.findById(paymentBody.user_id) .populate(User.schedule_table) .exec((err, foundDocument) => { console.log(foundDocuments) return foundDocument; }); console.log(user)
The code inside .exec (console.log(foundDocuments)), returns the result of query. However, when I perform console.log(user) after the query, it shows undefined.

I've created a script to parse few data points from an htmlfile link and write the same to a csv file according to this format. I do locate the fields accordingly using the selectors I've already defined within the script, but I can't stratify the output in the right way so that I can write them later to a csv file. location of data points: Nature of association `from 1st table` Purpose In cash (Previous balance) `from 2nd table` Donor Name Address `from 3rd table` Country Name Amount

I had a script to send a file to anonfiles.com for sharing using requests. It emulates the suggested curl command: curl -F "file=@test.txt" https://api.anonfiles.com/upload
with open(filename, 'rb') as file: req = requests.post( 'https://api.anonfiles.com/upload', files={'file': file}, ) res = json.loads(req.text)
This worked properly for files smaller than 2GB, but when the file grew bigger, it started printing a error message about the filesize. I tried to using requests-toolbelt to send the file with no success. with open(filename, 'rb') as file: encoder = MultipartEncoder({'file': file}) req = requests.post( 'https://api.anonfiles.com/upload', data=encoder, headers={'Content-Type': encoder.content_type} ) res = json.loads(req.text)
Which returns a the followinf error from anonfiles.com: { "status": false, "error": { "message": "No file chosen.", "type": "ERROR_FILE_NOT_PROVIDED", "code": 10 } }
I'm probably missing something obvious, but can't figure it out right now. P.S.: the use of requests-toolbelt.MultipartEncoder is not mandatory, I tried it and didn't manage to make it work. I will accept any answer even if it doesn't include this. A solution without request is not optimal but would also work.

I know that in each epoch we have a new set of augmentation. But my question is that if we have a total of 10 sample image, batch_size = 5, and we took steps_per_epoch = 3 instead of 2, then we will pass 5*3 = 15 images in each epoch, so definitely we will have repetition, my question is that if image x is repeated, will both have the same augmentation value or different.
It depends on whether new augmentation happens in each batch or in each epoch. Thanks,
