Hi, I use onedrive to transfer the FBX animation to hololens local storage, I’m not running python on the hololens device. As far as I can tell, apps can only be installed through windows store / building a ‘windows app’ with visual studio.
There doesn’t seem to be an easy way to run python on the hololens device, it is not running linux or windows 10, but a different operating system, “Windows IoT”, I think finding out how python interacts with Windows IoT would be your best bet.
In some quick googling, I found something that may provide clues, but CPython and Windows IoT core are above my head I’m afraid. Best of luck.
