USD+prman on windows failed to open

[hyc0612]

I am trying to build prman renderer and use it in usdview, the prman renderer build was successful but failed in running. Can anyone help me with this?

I have tried to run the build_usd.py in the following command python D:/OpenUSD/build_scripts/build_usd.py -v --build-variant debug --ptex --openvdb --openimageio --alembic --materialx --prman --prman-location "C:\Program Files\Pixar\RenderManProServer-25.2" "D:/install/USD_prman_embree" according to https://openusd.org/release/plugins_renderman.html

and then add variables PYTHONPATH, RMANTREE, RMAN_SHADERPATH, etc to path.

but when I open usdview and choose to render with prman, erros comes out as:

Warning: in Load at line 126 of D:\OpenUSD\pxr\imaging\plugin\hdPrmanLoader\rendererPlugin.cpp -- Could not load versioned hdPrman backend: The specified procedure could not be found.
