Incorrect path concatenation

[EltonCN]

Using with Windows, the "os.path.join(model_base_path, weights_manifest_path)" in line 81 of download.py generates a wrong URL with "" separator.

Changing to "model_base_path+"/"+weights_manifest_path" corrected the problem

Thank you for reporting the issue. I guess that is only an issue when model_base_path is not a local path?

It's fixed in source and will be included in the next release

The fix is now released (v0.3.3)
