@howlieT Thanks for reporting! Wonder if you have tried ?

[howlieT]

Hi,

I've tried this, it's running 64bit on a 64bit system, and i'm running it on pythn 3.9 to ensure it's supported.

[jay-patel-haptikai]

same issue with me Mac M1 python 3.9.13

[YunchuWang]

thanks for following up, can you share the code @howlieT ? trying to repro on my end.

[YunchuWang]

cant repro on my end,

can you check whats defined in core-tools grpc package init file?

[howlieT]

This is the code I was trying to run, I think it might've been a fault in the specific environment because I've been working around it by using a different environment and venv

@howlieT thanks for sharing. i am unable to repro in my local setup. glad it works when you change env, i would assume its a specific environment error.

Found Python version 3.9.13 (py).
