ImportError undefined symbol: iJIT_NotifyEvent when MKL 2024.1 is installed #127

Closed davidwhealey closed 2 months ago

davidwhealey commented 2 months ago

When using environment-detector.yml to install the cameratraps-detector environment, importing pytorch from within that environment raises an undefined symbol: iJIT_NotifyEvent error. Pytorch may fix this at some point, but in the meantime pinning mkl to version <= 2024.0 works.

Addressed in this issue.

Good catch! I was able to reproduce this issue (which I had missed because I had cached mkl versions on every machine I work on). All the package versions in that environment file are pinned to minimize issues just like this, but one of those packages must be taking a dependency on an unpinned version of mkl.

I verified that forcing mkl=2024.0 in the environment file fixes this. If you get a chance, please verify, but I'm sufficiently confident that I'm closing the issue.

This is going to come up for a zillion projects; MegaDetector is the least of PyTorch's concerns here. :)

Thanks for finding this!
