[SOLVED] How to Implement DSFD on Windows, Mac, and Linux

[david-littlefield]

Here's an article I wrote that shows how to get the demo working on Windows, Mac, and Linux

Thank you so much david, however I faced anouther error too. Can you have any solution about it?

test_oneimage()
  File "/home/berkanttugberk/GithubProjects/FaceDetection-DSFD/demo.py", line 190, in test_oneimage
    det0 = infer(net , img , transform , thresh , cuda , shrink)
  File "/home/berkanttugberk/GithubProjects/FaceDetection-DSFD/demo.py", line 71, in infer
    y = net(x)      # forward pass
  File "/home/berkanttugberk/miniconda3/lib/python3.9/site-packages/torch/nn/modules/module.py", line 727, in _call
_impl
    result = self.forward(*input, **kwargs)
TypeError: forward() missing 1 required positional argument: 'x'

Hi-there @berkanttubi. Is that the entire error message?

Here is the entire message;

@berkanttubi You will need to make the changes that are covered in the article to prevent these errors.

@david-littlefield I did :)

The first step in the "Fix the Errors" section should solve this problem.

Can you send a screenshot of your code from the stated files at the stated lines of code?

@david-littlefield I think the problem was about the torch version. When I downgraded it, the code worked. Thank you so much for your article David. I couldn't do it without your instructions. But I have another question,
It seems the model is very slow. I tried to work with 30 fps 30 sec video, and it took 280 sec to detect it. Isn't it a bit slow? What should fps be, any idea?

[david-littlefield]

@berkanttubi Good. Glad you were able to get it working! I've only used DSFD with single images, but I vaguely remember the paper stating something about the model not being fast enough to handle live video. What kind of GPU are you using?

im getting the following error

i dont know what to do
