DeepLabCut-live can't run test after installation on windows

hi. I am trying to install on Win10. in anaconda terminal I ran:

conda create -n dlc-live python=3.7 tensorflow==1.13.1
conda activate dlc-live
pip install deeplabcut-live

all went smoothly.

When I ran dlc-live-test I got the following error. Please help. Thank you.

Will anyone please share a environment.yml that works. Many thanks.

Hmm so the n_frames value that is apparently negative is computed here: https://github.com/DeepLabCut/DeepLabCut-live/blob/b60f21b3ff4a0b8b7add868c35906362dfe94446/dlclive/benchmark.py#L236-L240

so looks like there must be some problem either with opencv or with the video file. Opencv capture properties are sort of notoriously fragile and unneccessarily platform/backend dependent, so that could be a thing. Could you check if the dog video (at location above) is correctly downloaded and plays?

The video file is 183kb and can't be played with the players I've got. I've tried to delete it yet the newly downloaded video remained the same.

That would do it. The video is 1.25MB, no idea why the download might be failing, but try replacing it manually: https://github.com/DeepLabCut/DeepLabCut-live/blob/main/check_install/dog_clip.avi

I've tried that. But when I run dlc-live-test it downloads again and replaces the good video file with the 183kb broken file.

weird... it shouldn't: https://github.com/DeepLabCut/DeepLabCut-live/blob/b60f21b3ff4a0b8b7add868c35906362dfe94446/dlclive/check_install/check_install.py#L54-L59

ah it's probably because the package hasn't been re-released on pypi since https://github.com/DeepLabCut/DeepLabCut-live/pull/126

@AlexEMG can you make a release please?

This should be fixed in the latest release, closing for now.
