Local downloads not working on Windows

[JuhaKiili]

If you have this code

import valohai
valohai.prepare(step="train", default_inputs={"test": "https://upload.wikimedia.org/wikipedia/en/a/a9/Example.jpg"})
print(valohai.inputs("test").path())

And run it in Windows, you get a path like:

.valohai/inputs\\test\\example.jpg

The consts.py hardcodes the POSIX path separator, which doesn't work on Windows. Need to fix that.

It should work just fine, though – Python's path manipulation bits internally convert slashes to the platform-native direction.
