CUTENSORNET_STATUS_CUTENSOR_VERSION_MISMATCH in line 198 #8

Closed davide-q closed 1 year ago

davide-q commented 1 year ago

I am trying to compile the examples in the /samples/cutensornet directory and the compilation is successful, however it fails at runtime with the error in the subject.

According to https://github.com/NVIDIA/cuQuantum/blob/main/samples/cutensornet/README.md and https://docs.nvidia.com/cuda/cuquantum/cutensornet/index.html as of today, I must have

I actually have

So I meet all the requirements but still get that error. The only thing I can think is that libcutensor libraries are split in 3 directories for 10.2, 11, and 11.0 so perhaps CUDA v11.7 is too new? Does anybody has any insight?

Hi @davide-q thank you for reaching out. This is a known issue which will be patched in the 22.07.1 update we hope to be posting in the next few days.

In the interim you can circumvent this error by downgrading cuTENSOR to a 1.5.x version. Please let us know how it goes.

Hi @davide-q I wanted to follow up to see if the above solved your issue or if you had any more updates for us? If not do you mind if I close this out?

davide-q commented 1 year ago

@tlubowe thanks for checking. I don't want to downgrade, so I am waiting for the update, has it been posted?

tlubowe commented 1 year ago

Hi @davide-q, 22.07.1 is currently going through our pipeline for QA, packaging and deployment. It is not posted yet. I will post back here when it is.

Hi @davide-q and all, v22.07.1 is out (#11), it'd be nice if you could give it a shot and let us know, thanks! 🙂

davide-q commented 1 year ago

Perfect, thanks so much. I will test it asap (=early next week) and report back.

leofang commented 1 year ago

Closing this issue as it's resolved in 22.07.1. @davide-q let us know if you still hit issues, thanks.
