Streamlit install crashes Carnets plus

[ifuchs]

Has anyone tried to install Streamlit (Webapp development platform)? When I tried, Carnets crashed.

[ifuchs]

Carnets plus still crashes during the install. However Carnets (not plus) seems to complete the install:

Successfully installed altair-4.2.0 astor-0.8.1 base58-2.1.1 blinker-1.4 click-8.0.4 gitdb-4.0.9 gitpython-3.1.27 importlib-metadata-4.11.2 protobuf-3.19.4 pyarrow-7.0.0 pydeck-0.7.1 pympler-1.0.1 semver-2.13.0 smmap-5.0.0 streamlit-1.6.0 toml-0.10.2 toolz-0.11.2 validators-0.18.2 widgetsnbextension-3.5.2 zipp-3.7.0

But when I then import streamlit, I get:

[holzschu]

From the line at the bottom of the error message, the issue is with pyarrow. pyarrow is an Apache library which has C components, so it makes sense that it cannot be installed. Since streamlit has a dependency on pyarrow, it cannot be installed either.

[ifuchs]

Any chance of pyarrow being added so that Streamlit could be installed?
