Default pyo3 dependency causing problems on ios builds

[rubiktubik]

I have build the previous versions of mistralrs for ios without problems.

But with the latest version i'am getting the following error in xcode:

Error (Xcode): failed to run custom build command for `pyo3-ffi v0.25.1`
/Users/user/Documents/Projects/flutter/experimental/my_mistral_rs/ios/Pods/SEVERE:0:0


Error (Xcode): PYO3_CROSS_PYTHON_VERSION or an abi3-py3* feature must be specified when cross-compiling and
PYO3_CROSS_LIB_DIR is not set.
/Users/user/Documents/Projects/flutter/experimental/my_mistral_rs/ios/Pods/SEVERE:0:0

It seems mistral-rs is using a default pyo3 dependency.

Can i disable this dependency?

removing default features did not worked out

mistralrs = { git = "https://github.com/EricLBuehler/mistral.rs.git", branch = "master", features = [ "metal", ], default-features = false }

Great library btw!

Can i disable this dependency?

It was previously possible to opt-out, but then @EricLBuehler migrated to using a Cargo workspace for the project and something about that change made things go awry.

I mentioned it recently here where the requirement for Python was added into the Docker image builds as a quickfix workaround.

@EricLBuehler do you have an advice how to disable this dependency?

Hi @rubiktubik - thanks for the issue! Just merged #1478 which should fix this. Can you confirm?

This actually came from mistralrs_mcp (the MCP client crate). I think we can get rid of the python requirement - what do you think @polarathene?

[polarathene]

Thanks for spotting the actual cause 😅 Yeah if Python isn't needed anymore it should be dropped from the image dependencies.

[EricLBuehler]

Made a PR to do this: #1487.

Thank you very much for the quick help @EricLBuehler my build error is gone!
