#3451 [BUG] pyflyte run fails on Windows Issue created by jboutwell-rva Running the following in the command prompt fails:

pyflyte run --remote example.py training_workflow --hyperparameters "{\"C\": 0.1}"

Error:

{"asctime": "2023-03-11 11:32:20,895", "name": "flytekit", "levelname": "WARNING", "message": "FlyteSchema is deprecated, use Structured Dataset instead."} Failed with Exception: Reason: SYSTEM:Unknown Underlying Exception: cannot find context for 'fork'

The example is taken from https://docs.flyte.org/projects/cookbook/en/latest/index.html. The error appears to be caused by this line: https://github.com/flyteorg/flytekit/blob/master/flytekit/clients/auth/auth_client.py#L308 The python multiprocessing docs indicate only "spawn" is supported on Windows, and as of 3.8 is also recommended for macOS. Version Info Windows 10 Python 3.10.10 flytekit-1.4.1 The same example works for me on macOS. flyteorg/flyte
