[nitramsivart]

I see that my google-auth version is old (1.6.3), so maybe this is actually an issue of my not upgrading all dependencies properly.

[arithmetic1728]

@nitramsivart yes, please upgrade google-auth. mtls is not defined in the old version.

[nitramsivart]

Thank you, that resolved my issue!

[nitramsivart]

Note, this is still an issue when I install this package with conda install, because these dependency requirements haven't been updated in the conda recipe: conda-forge/google-api-python-client-feedstock#39

[busunkim96]

Hmm, I'm not entirely sure how this package is published to conda. @meredithslota?

[nitramsivart]

Pretty sure it's published using conda-smithy, as described a bit more in README of this reop: https://github.com/conda-forge/google-api-python-client-feedstock

What's unclear to me is if anybody owns keeping this up to date, or it's just as needed

[busunkim96]

Closing as this has been addressed by the folks who manage the repo mentioned above.

I still get the error even though my pip list shows the version google-auth 1.17.2

I am using that in a Jupyter Notebook with Python 3.

[busunkim96]

@A-Sm1th Can you double check the version? The latest published version is 1.9.2

[arithmetic1728]

@A-Sm1th I tested google-auth 1.17.2 and it worked fine.

(tmp) $ python -m pip freeze
cachetools==4.1.0
google-auth==1.17.2

[nitramsivart]

Why is this being assigned to me?

[arithmetic1728]

This issue is already closed, not sure what happened to the assignment.

[akram-ali-cs]

google-api-python-client version: 2.2.0

From yesterday getting this error, I've updated with the latest version as well.

[arithmetic1728]

@akram-ali-cs I just tested 2.2.0, it worked fine. Maybe you need to update google-auth to latest version.

This is still a problem for me. Even after installing the latest version of google-auth, I get the following error.

$ pip install google_auth
Installing collected packages: google-auth
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
google-colab 1.0.0 requires google-auth~=1.4.0, but you have google-auth 1.32.0 which is incompatible.

I already have the following installed versions:

google-colab==1.0.0
tensorflow==2.5.0
tensorflow-cloud==0.1.16

[parthea]

Hi @ fisakhan,
For google-api-python-client, the following error is valid:
google-api-python-client 1.12.8 requires six<2dev,>=1.13.0, but you have six 1.12.0 which is incompatible.

six>=1.13.0 is required in the google-api-python-client setup.py file. Simply run pip install six==1.13.0.

[fisakhan]

Now I get the following error:

$ pip install six==1.13.0
Collecting six==1.13.0
  Downloading six-1.13.0-py2.py3-none-any.whl (10 kB)

tensorflow, google-colab and google-auth require different versions of six.

[parthea]

I see. Yes, it looks the compatible release ~= requirement for tensorflow and google-colab is potentially an issue.

In google-api-python-client the requirement is six>=1.13.0,<2dev so any version 1.13.0 or higher but less than 2dev will work.
In tensorflow, the requirement is six~=1.15.0, so only versions like 1.15.* will work
In google-colab, the requirement is six~=1.12.0, so only versions like 1.12.* will work

Please open an issue in the respective repos as there is no improvement for this repo.
