NUM_WORKERS param

[shokhova-eve]

Good day!

I'm working on the project that draws heatmaps on the website screenshots using patterns of scanning pages and partial detecting WebUI elements by computer vision, so obviously I quickly found your work and that repo. I'm trying to start it on your set of data. I downloaded all packages on Python 3.7 and I'm trying to start application on Windows with

python main.py -cvf -1

In constants.py I added
DATA_DIR = "C://Users/Lenovo/Downloads/cova-data"

Error I'm getting is

Traceback (most recent call last):
  File "main.py", line 100, in <module>

    raise URLError('unknown url type: %s' % type)

If I try to set NUM_WORKERS by commandline arg like this

python main.py -cvf -1 -nw 3

it doesn't help.

Could you, please, help me to understand what can cause this issue?
Thank you a lot.

I think its the issue with the dataset path C://Users/Lenovo/Downloads/cova-data since numpy is trying to load the files from external URL using requests. Can you changing the path to ../../cova-data and see if it works?
