you need upgrade the pytorch_java_only.jar to version 1.5.0.

[aaronlyt]

https://download.pytorch.org/libtorch/cu102/libtorch-shared-with-deps-1.5.0.zip， is not 1.5.0?

[ares89]

https://download.pytorch.org/libtorch/cu102/libtorch-shared-with-deps-1.5.0.zip， is not 1.5.0?

yes,libtorch version is 1.5.0, but what's the version of your pytorch_java_only.jar ?

[aaronlyt]

I downloaded from the link, it's 1.5.0

Can you try with the latest release and tell me if you're still seeing this? Please make sure that the version of libtorch that you've downloaded matches the jar that you're using.
