if torch._six.PY3: AttributeError: module 'torch._six' has no attribute 'PY3' #1341

from maskrcnn_benchmark.utils.imports import import_file File "/home/nikhilanand_1921cs24/Souryadip/Extra/vilbert-multi-task/maskrcnn-benchmark/maskrcnn_benchmark/utils/imports.py", line 4, in if torch._six.PY3: AttributeError: module 'torch._six' has no attribute 'PY3'

Error showing while running the script after installation.

torch version : 1.10.1, Cuda : 11.3, python : 3.7.13

Found out torch._six.PY3 is not available with the latest pytorch versions. But, .PY37 is present in the torch._six module. So, Changing .PY3 to .PY37 in the imports.py file worked somehow and the code ran without any issue.

Hi, could you share some tips to run on CUDA >= 11 / torch >= 1.10? (python3.7) When I call python setup.py build develop, compile error raised.

ninja: build stopped: subcommand failed.
Traceback (most recent call last):

    output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

The above exception was the direct cause of the following exception:
