Error when I try to run example code: from grpc._cython import cygrpc as _cygrpc ImportError: cannot import name 'cygrpc'

[antoineChammas]

In which file did you encounter the issue?

I used the code in the tutorial on my local machine

https://codelabs.developers.google.com/codelabs/cloud-vision-api-python/index.html?index=..%2F..%2Findex#5

Did you change the file? If so, how?

No

Describe the issue

When running the example code locally, I get the error mentioned in the title:
from grpc._cython import cygrpc as _cygrpc ImportError: cannot import name 'cygrpc'

[antoineChammas]

the problem was with the grcp library not with google cloud, in case anyone stumbles on the same mistake, run python -m pip install grcpio --ignore-installed

[xueluofeng]

"python -m pip install grcpio --ignore-installed" , is grpcio not grcpio;
But to me is invalid

[zhaodi-Wen]

you can use "python -m pip install grcpio --ignore-installed"

[xiaoyangnihao]

is this "python -m pip install grpcio --ignore-installed" useful ? It seems invalid to me, I met the same error, and don't know how to solve it.

conda install grpcio works for me

Specifying version as grpcio==1.27.2 resolved my issue

Did you find a way to solve this?

Specifying version as grpcio==1.27.2 resolved my issue

this doesn't work for python 3.9 due to incompatibility issue:

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - grpcio==1.27.2 -> python[version='>=2.7,<2.8.0a0|>=3.8,<3.9.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']

Your python: python=3.9

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

Is there a way to solve this?

python3.8 -m pip install -U grpcio worked for me.

cannot import name 'cygrpc' from 'grpc._cython' (/opt/python/grpc/_cython/__init__.py)

If you are still facing the same issue with AWS Lambda layer and using mac for building the package locally.
Then the solution is to just use linux (ubuntu) to build your google-cloud-* package. It will solve the issue.

@roshanlabh Can you provide a link with some detail on how to use linux (ubuntu) to build your google-cloud-* package? Thanks!
