Why am I getting an
OSError: [Errno 22] Invalid argument error and therefore a
Vector file is not provided exception while the model is being loaded?
If you are getting this error, it is very likely that you are running macOS and using Python with version <= 3.6.7 or <= 3.7.1. If this is the case, then you are affected by a known Python bug on macOS, and upgrading your Python to >= 3.6.8 or >= 3.7.2 should solve this issue.
If you are not running macOS or already have the specified Python version and still seeing this issue, please report this to us via the GitHub issue tracker.
