Hi,

I have a model JIT-compiled in R torch that loads fine in PyTorch 1.9. However, I can't load it from Java:

Exception in thread "main" com.facebook.jni.CppException: open file failed, file path: /tmp/model-deploy.pt

Would you by chance have an idea what could be the reason/ how to make progress with this?

Many thanks!!

Also tried re-building my R torch to use the pre-CXX 11 ABI as well, but still get same error.
