confirmed that #36 resolved this problem by installing main branch in colab and running example steps from the readme

thanks @freeshrugsxd for identifying a solution for part of the problem

Hey, the problem is that the requests library cannot handle backslashes in URLs and in the utils.py there is a line where a base-URL is concatenated with a file name using os.path.join which, on Windows, uses a backslash as seperator. So you end up with a URL that looks like this:
https://github.com/distant-viewing/dvt/releases/download/0.0.1\\dvt_detect_face.pt

which fails, because requests.get('https://github.com/distant-viewing/dvt/releases/download/0.0.1\\dvt_detect_face.pt') returns 404.

To fix this, change this line:

dvt/dvt/utils.py

Line 121 in dea8bbf

url = os.path.join(basename, url)

into something like this:

url = basename + '/' + url or url = f'{basename}/{url}'
