QUESTION
Problem
I have a large JSON file (~700.000 lines, 1.2GB filesize) containing twitter data that I need to preprocess for data and network analysis. During the data collection an error happend: Instead of using " as a seperator ' was used. As this does not conform with the JSON standard, the file can not be processed by R or Python.
Information about the dataset: Every about 500 lines start with meta info + meta information for the users, etc. then there are the tweets in json (order of fields not stable) starting with a space, one tweet per line.
This is what I tried so far:
- A simple
data.replace('\'', '\"')
is not possible, as the "text" fields contain tweets which may contain ' or " themselves. - Using regex, I was able to catch some of the instances, but it does not catch everything:
re.compile(r'"[^"]*"(*SKIP)(*FAIL)|\'')
- Using
literal.eval(data)
from theast
package also throws an error.
As the order of the fields and the legth for each field is not stable I am stuck on how to reformat that file in order to conform to JSON.
Normal sample line of the data (for this options one and two would work, but note that the tweets are also in non-english languages, which use " or ' in their tweets):

Answered 2021-Jun-09 at 04:36So with meshgrid, using the shape of the self.im
, we first find the coordinates of the X
and Y
values in the 2D image. Then, we find all values whose coordinates follows the circle rule ((X - Ox) ** 2 + (Y - Oy)**2 <= R**2
).
QUESTION
For my project, I am using tensorflow to predict handwritten user input.
Basically I used this dataset: https://www.kaggle.com/rishianand/devanagari-character-set, and created a model. I used matplotlib to see the images that were being produced by the pixels.
My code essentially works with training data, but i want to up it up a little. Through CV2, I created a GUI that allows users to draw a Nepali Letter. After this, I have branching that tells the program to save the image inside the computer.
This is a snippet of my code for it:

- there are 46 different characters/alphabets
QUESTION
I am implementing simple DQN algorithm using pytorch
, to solve the CartPole environment from gym
. I have been debugging for a while now, and I cant figure out why the model is not learning.
Observations:
- using
SmoothL1Loss
performs worse thanMSEloss
, but loss increases for both - smaller
LR
inAdam
does not work, I have tested using 0.0001, 0.00025, 0.0005 and default
Notes:
- I have debugged various parts of the algorithm individually, and can say with good confidence that the issue is in the
learn
function. I am wondering if this bug is due to me misunderstandingdetach
in pytorch or some other framework mistake im making. - I am trying to stick as close to the original paper as possible (linked above)

Answered 2021-Jun-02 at 17:39The main problem I think is the discount factor, gamma. You are setting it to 1.0, which mean that you are giving the same weight to the future rewards as the current one. Usually in reinforcement learning we care more about the immediate reward than the future, so gamma should always be less than 1.
Just to give it a try I set gamma = 0.99

first of all run this npm unistall bcrypt
then npm install bcryptjs
. it will work.
but make sure you change for import package like this
import bcrypt from 'bcryptjs';
QUESTION
Im trying to display a greyscale image (made with matplotlib) in a tkinter Frame. The image itself is displayed, but only with some whitespace between each side of the actual image and the tkinter Frame border. Any ideas on how i can avoid drawing the image with the whitespace?
My code that i currently use:
...ANSWER
Answered 2021-May-28 at 17:55It looks like the whitespace exists both in the plot and in the GUI, so the problem lies on the matplotlib side. The fig.subplots_adjust(left=0.01, right=0.99, top=0.99, bottom=0.01)
method can reduce this whitespace.
QUESTION
I tried the code provided bellow to segment each digit in this image and put a contour around it then crop it out but it's giving me bad results, I'm not sure what I need to change or work on.
The best idea I can think of right now is filtering the 4 largest contours in the image except the image contour itself.
The code I'm working with:
...ANSWER
Answered 2021-May-25 at 23:48You almost have it. You have multiple bounding rectangles on each digit because you are retrieving every contour (external and internal). You are using cv2.findContours
in RETR_LIST
mode, which retrieves all the contours, but doesn't create any parent-child relationship. The parent-child relationship is what discriminates between inner (child) and outter (parent) contours, OpenCV calls this "Contour Hierarchy". Check out the docs for an overview of all hierarchy modes. Of particular interest is RETR_EXTERNAL
mode. This mode fetches only external contours - so you don't get multiple contours and (by extension) multiple bounding boxes for each digit!
Also, it seems that your images have a red border. This will introduce noise while thresholding the image, and this border might be recognized as the top-level outer contour - thus, every other contour (the children of this parent contour) will not be fetched in RETR_EXTERNAL
mode. Fortunately, the border position seems constant and we can eliminate it with a simple flood-fill, which pretty much fills a blob of a target color with a substitute color.
Let's check out the reworked code:
