Cannot Import Name ‘cygrpc’ from ‘grpc._cython’

In this Azure tutorial, we will discuss fixing the error, Cannot Import Name ‘cygrpc’, which I got while trying to run my Python Azure Function in the Visual Studio Code.

Cannot Import Name ‘cygrpc’ from ‘grpc._cython’

Recently, I had a requirement to create an Azure Function in Python using Visual Studio Code. I have created the Python Azure Function, and when I press F5 to run the Azure Function to test it locally to check if the Azure Function is working, Immediately I get the error “ImportError: cannot import name ‘cygrpc'”.

You can see the error as below

importerror: cannot import name 'cygrpc' from 'grpc._cython'

Now I have started searching for the fix of this issue, What I came to know is This error occurs when a Python function app fails to start with a proper Python interpreter. Mostly, you will get this error if you have installed 32-bit Python interpreter on your 64-bit operating system.

Now, We need to check the Python interpreter bitness is correct or not. To check that,

Open the Windows PowerShell and run the below command

py -c 'import platform; print(platform.architecture()[0])'

So, when I ran the command I could able to see that the interpreter is 32 bit whereas the operating system on which I am working is 64 bit. So this is what the root cause of the issue is.

Now To fix this issue, I have followed the below steps

Navigate to the Python Official site https://www.python.org/downloads/ to download the 64 bit Python interpreter

Clicked on the 64 bit executable file link, It downloaded the 64-bit exe in my local system.

importerror: cannot import name 'cygrpc' from 'grpc._cython' (c:\program files\microsoft\azure functions core tools\workers\python\3.9\windows\x64\grpc\_cython\__init__.py)

Now, I double click on the exe file that I have downloaded to install in my local system

error: unhandled error in functions worker: cannot import name 'cygrpc' from 'grpc._cython'

After I have installed this successfully, I have again click on the Run button to run the Azure Function project in the Visual Studio Code. This time I didn’t get any error. I got the expected OutPut

cygrpc

So, this is how I can able to fix the error Cannot Import Name ‘cygrpc’.
