"pip install numpy" fails because of Fortran

[AapoTahkola]

camera requires numpy. camera is required by mqtt. On top of that mqtt is required by tasmota. "pip install numpy --no-cache-dir --force-reinstall --no-binary :all -v --log /root/numpy_inst2" fails with

Any ideas on how to get around this issue? Seems to be same regardless of version. Why is HA depending on Fortran anyway?

Yes, it should be cross-compiled, but numpy requires floating point support in the CPU. What component requires numpy btw?

I found this churning along with top command:

"Setup failed for camera: Requirements for camera not found: ['PyTurboJPEG==1.6.6']."

Can esphome work without mqtt or why are people preferring it over tasmota? I am a bit overwhelmed on what I still need to fix. mqtt seems to work at times but I have no devices yet.

[devbis]

You should remove PyTurboJPEG from "camera" and "stream" components on your installation. Open manifest.json and leave the requirements = []. Those ones won't work without numpy.

Can esphome work without mqtt

Yes, it can. It uses internal HA API to communicate while Tasmota uses MQTT. ESPHome is more native and possibly provides more options, while tasmota is restricted with HA MQTT discovery functionality.

Actually I just looked one of my tasmota devices just autoconfigured itself and shows up. Yeay!! Very responsive no lag at all.

Anyway, I do not know should something be done about these errors.

Remove the requirements from camera/manifest.json and stream/manifest.json
