If normal installation fails for MacOS there may be an issue in the dependencies.
During my installation process I ran into the following problems:
- error could not build “grpcio” wheels
- xcrun error: invalid developer path
→ My xcode was not up to date
→ FIX: $ xcode-select --install
→ Found here
- xcrun: error: invalid active devel… | Apple Developer Forums
- Add instruction for building on macOS with M1 chip by Alyetama · Pull Request #30316 · grpc/grpc · GitHub
Once I got that sorted, everything was installed but upon running in python
import bayesflow as bf
I got the error:
“zsh: illegal hardware instruction”
This is a known error for tensorflow in M1 Chips. The way I got around this was following
this YouTube tutorial (https://www.youtube.com/watch?v=WFIZn6titnc) whose steps are abbreviated below.
