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

In this Azure tutorial, we will discuss how to fix the error ‘Cannot Import Name ‘cygrpc’ I encountered while trying to run my Python Azure Function in 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 made a Python Azure Function, and when I press F5 to run it locally for testing, I immediately receive the error “ImportError: cannot import name ‘cygrpc’.”

You can see the error below.

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

Now, I have begun searching for a solution to this issue. I learned that this error occurs when a Python function app fails to start with a proper Python interpreter. You will mostly get this error if you have installed a 32-bit Python interpreter on your 64-bit operating system.

Now, we need to verify that the Python interpreter’s bitness is correct. To check that,

Open Windows PowerShell and run the command below.

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

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

Solution

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

Navigate to the Python Official site to download the 64-bit Python interpreter

Clicked on the 64-bit executable file link, and it downloaded the 64-bit EXE file to 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 on my local system.

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

After I had successfully installed it, I clicked the Run button again to run the Azure Function project in Visual Studio Code. This time, I didn’t get any error. I got the expected output.
