ImportError when trying to run usdcompress

On a clean build, usdcat runs fine, usdcompress fails.

Hello @safasofuoglu , I suspect this may be because you are using python 3.9 on windows. Issue #1404 is fixed in the forthcoming USD 21.08 release - can you try again there when it comes out shortly (or in the dev branch if you don't want to wait)?

Hi @spiffmon , as I specified in the report, I built from https://github.com/PixarAnimationStudios/USD/commit/e40995f6360f485512566fec5854b5f170784ff2 and usdcat runs fine.

I'm claiming #1404 may not have fixed usdcompress.

spiffmon commented 3 years ago

Ah thanks… this may then be due to usdDraco being a plugin rather than a lib. This came up before but I don’t recall whether there was a resolution or not. We’ll try to take a look, but I can’t promise timing.

Hi @safasofuoglu -- I suspect @spiffmon is right. I suspect the issue is that none of the usdDraco symbols are exported and that is only surfacing as a problem on Windows.
