cloudpathlib fails with no_sign_request=True

[d33bs]

Using cloudpathlib==0.18.1 there appears to be a bug which causes cloudpathlib to seek credentials for AWS connections despite passing no_sign_request=True. The error appears as: botocore.exceptions.NoCredentialsError: Unable to locate credentials. On testing this in isolation without CytoTable, a different bug seems to manifest as: NameError: name 'Session' is not defined. See here: https://gist.github.com/d33bs/eb19f864baae89757e0e0969611cf1af .

Using existing code from CytoTable to mimic an example appears to work okay:

from cloudpathlib import AnyPath, CloudPath

path = "s3://ladi/Images/FEMA_CAP/2020/70349/DSC_0001_5a63d42e-27c6-448a-84f1-bfc632125b8e.jpg"

processed_path = AnyPath(path)

if isinstance(processed_path, CloudPath):
        processed_path.client = processed_path.client.__class__(no_sign_request=True)

# use this client object to create the CloudPath
processed_path.exists()

Opened issue for the Session bug mentioned above through drivendataorg/cloudpathlib#441

[d33bs]

NameError: name 'Session' is not defined portion of this bug was caused by a missing dependency from cloudpathlib (required optional specification).

Closing this issue as the bug no longer appears to persist as demonstrated by passing tests with real AWS S3 data sources within https://github.com/cytomining/CytoTable/blob/main/tests/test_convert_threaded.py . I believe it may have been due to missing optional installs from cloudpathlib in variable development environments.
