Neptune Logger assumes unix-style filepath for model checkpoint #10602
Description
The Neptune Logger can automatically upload model checkpoints if the callback is used. It generates an "expected_model_path" for that. This path has hard-coded a '/' at the end (see here), which can cause problems on Windows systems because the actual path has (or can have) a backslash at this position. A simple fix would be to use os.path.sep insteat of '/'.
