Heads up: torch 1.9.1 currently causes error

[ourownstory]

Hyperparameter tuning runs into error:
ImportError: cannot import name 'container_abcs' from 'torch._six'

Also discussed in:
NVIDIA/apex#1049

torch 1.8.1 or 1.7.1 does not throw this error

Thanks for reporting, and also the NVIDIA/apex link. I had run into the same issue this morning on torch 1.9.0. It seems this torch 1.9.0 change broke many projects. In my case, however, the error came from time_series_parameter_tuning when it imports ax, which in turn imports botorch, which then triggers the ImportError. Was it the same for you? If so, then this bug is upstream; the only thing Kats can do is try to change the version requirements for ax and/or botorch.
