I run into the same issue, but only with Python 3.6. It works with 3.7. Also, this only happens with kaleido 0.2.0.

Thanks for the report.

Looks like an import cycle that for some reason Python 3.6 can't resolve. Fix to kaleido on the way, but it may not be until tomorrow before the everthing churns through the release process. If you are hitting this problem, please continue to use version 0.1.0 until 0.2.1 is out.

@boehmseb @Djeramon Please try the 0.2.1 release from the Kaleido GitHub release page (I'm going to wait to upload to PyPI and anaconda.org until something gives a 👍 that this fixed this issue for them)

For linux x86_64:

pip install https://github.com/plotly/Kaleido/releases/download/v0.2.1/kaleido-0.2.1-py2.py3-none-manylinux1_x86_64.whl

for other operating systems, look for the appropriate wheel file under https://github.com/plotly/Kaleido/releases/tag/v0.2.1, and pip install using the full url.

Thank!

I can confirm that kaleido 0.2.1 fixed the issue. Thanks for this quick fix.

[boehmseb]

Also works for me, thanks.

Great! Thanks for trying it out. 0.2.1 Packages are now published to PyPI and conda-forge.
