Setup:
- Home Assistant os
- Home Assistant 2021.10.6
- Intel NUC
I’m making a custom component (“mpc_thermostat”). It depends on scipy, which in turn depends on numpy. During installation (HA restart), I get errors from the installation of scipy (see below).
My interpretation is that scipy depends on numpy, which doesn’t have a prebuilt wheel for my environment (please correct me here!).
I tried to log into the homeassistant container (docker exec -it homeassistant bash) to install it manually. pip install scipy gives me a similar error. At the same time I can see that numpy 1.21.2 is already installed.
This doesn’t make sense to me, so I fear I’m missing something important. Can anyone shed some light on this for me?
Thank you
