The Industrial Raspberry Pi Forum

Dear all,

I'm trying to install the package pyarrow, which is used for another package (streamlit) on the revpi.
It fails using "pip install pyarrow" as there is no pre-compiled wheel and the ressources of the revpi seem to be not sufficient for compiling it locally.
Instead I tried to cross-compile it under Windows with docker for the revpi but also there I face problems with cmake. Cmake fails with the error "Unknown system processor" although I have used the option "-DSYSTEM_PROCESSOR=armv7l".

Does anyone faced similar problems and managed to compile the package for the revpi?

Thanks for all hints and help.

Best regards,
André

Looks like they provide wheels for aarch64: https://pypi.org/project/pyarrow/#files

Any reason you use a 32-bit image? Starting with Bookworm there will be only 64-bit images, so maybe it is a good opportunety and then switch to the official pyarrow wheel ?
