was requested, but nvcc
was not found. Are you sure your environment has nvcc available? If you're installing within a container from https
://hub.docker.com/r/pytorch/pytorch, only images whose names contain 'devel' will provide nvcc.
Warning
: Torch did not find available GPUs on this system.
If your intention is to cross-compile, this is not
an error.
By default, Apex will cross-compile for Pascal (compute capabilities 6.0, 6.1, 6.2),
Volta (compute capability 7.0), Turing (compute capability 7.5),
and, if
the CUDA version is >= 11.0, Ampere (compute capability 8.0).
If you wish to cross-compile for a single specific architecture,
export TORCH_CUDA_ARCH_LIST="compute capability" before
running setup.py.
torch.__version__ = 2.

: This
error originates from a subprocess,
