It looks like there is a problem with your grpc build as discussed here.

Can you give me your version of grpc pip show grpcio? Also are you using conda?

Same problem. Can be solved by rebuilding grpcio from source: source link.

Yeah this solves the problem, thanks!

Posting here the solution to facilitate:

pip uninstall grpcio
export GRPC_PYTHON_LDFLAGS=" -framework CoreFoundation"
pip install grpcio --no-binary :all:

I am still facing the same problem even after trying

pip uninstall grpcio
export GRPC_PYTHON_LDFLAGS=" -framework CoreFoundation"
pip install grpcio --no-binary :all:

from grpc._cython import cygrpc
ImportError: dlopen(/Users/123456/miniforge3/lib/python3.11/site-packages/grpc/_cython/cygrpc.cpython-311-darwin.so, 0x0002): symbol not found in flat namespace '_kCFStreamPropertySocketNativeHandle'

Can you try to disable the telemetry? Set enable_telemetry=false in .chainlit/config.toml. I think grpc is only used for that purpose.

i solved this issue with this method.

1. pip uninstall grpcio
2. add those three lines at the end of your .zshrc file

export GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=1
export GRPC_PYTHON_BUILD_SYSTEM_ZLIB=1
export GRPC_PYTHON_LDFLAGS=" -framework CoreFoundation"
3. pip install grpcio --no-binary :all:

I use conda environment and this works for me

1. pip uninstall grpcio
2. conda install grpcio

pip install grpcio gives me an error about not being able to build the wheel for grpcio.

pip uninstall grpcio

pip install grpcio --no-binary :all:

I made an error using this command, but I changed it to pip install --no-cache-dir --force-reinstall -Iv grpcio --no-binary :all: and it worked
