Kaleido cannot be installed through poetry? I will make it an optional dependency in the next release.

I had the same issue - with pipenv and poetry. Somehow the post1 version makes trouble/cannot be found. In the end I just forced poetry to use/install the version without post1

[tool.poetry.dependencies]
kaleido = "0.2.1"

Also kaleido can not be installed on Alpine linux, I am unable to upgrade vectorbt past v0.18, looking forward to this change!

[polakowo]

As a temporary solution, you can install the develop branch, which doesn’t have kaleido in the requirements.

Thanks @polakowo that got me moving ahead
