[dev] is what installs the group of optional dependencies.
pip install -e ".[dev]"
However, some tests are failing
Many tests are non-deterministic and occasionally fail. Does it happen if you re-run it again?
I guess I should move this discussion into the testing thread.
RuntimeError: DataLoader worker (pid 44770) is killed by signal: Unknown signal: 0.
Is a pytorch issue and usually has to do with not having enough of shared memory issue, please see:
- Give a better error when we run out of shared memory, instead of "RuntimeError: DataLoader worker (pid 13) is killed by signal: Bus error." · Issue #5040 · pytorch/pytorch · GitHub
- RuntimeError: DataLoader worker (pid 137) is killed by signal: Bus error - #11 by jeffhale
albeit it shouldn’t happen in the tests, since there is very little memory used there.
Also, are you running the latest pytorch-1.0.1?
Finally, if none of the above helps, please see our macOS CI setup steps that doesn’t have problems running the test suite: https://github.com/fastai/fastai/blob/master/azure-pipelines.yml#L315
please check if yours varies and what’s different.
