So moving onto the container name.
Original code has the following calls:

if not f.path.segments: raise ValueError( "URI {} is missing a container name (expected " "[https/azure]://<account-name>.../<container-name>)".format( uri ) ) container = f.path.segments[0]
Repeating the same commands locally results in the following:

` >>> f_a.path.segments
['artefacts', 'Caltech Birds%2FTraining', 'TRAIN [Network%3A resnet34, Library%3A torchvision] Ignite Train PyTorch CNN on CUB200.8611ada5be6f4bb6ba09cf730ecd2253', 'models', 'cub200_resnet34_ignite_best_model_0.pt']

if not f_a.path.segments:
... print('An error will be raised')
... else:
... print('No error will be raised')
...
No error will be raised
f_a.path.segments[0]
'artefacts'
f_b.path.segments
['artefacts', 'Caltech Birds/Training', 'TRAIN%20[Network%3A%20resnet34,%20Library%3A%20torchvision]%20Ignite%20Train%20PyTorch%20CNN%20on%20CUB200.8611ada5be6f4bb6ba09cf730ecd2253', 'models', 'cub200_resnet34_ignite_best_model_0.pt']
if not f_b.path.segments:
... print('An error will be raised')
... else:
... print('No error will be raised')
...
No error will be raised
f_b.path.segments[0]
'artefacts' `In both cases the Azure storage container name is correct as well.
