Having an error while trying to open TensorBoard in Jupyter Notebook?

Question

ERROR: Failed to launch TensorBoard (exited with 1).

I have tried running "pip install grpc" but it cannot find a module with that name. For some background info, I don't have an Nvidia GPU, in case that matters.

EDIT: "python -m pip install grpcio" solved my issue. However, I now have a new error.

have you tried:

python -m pip install grpcio

and potentially

python -m pip install grpcio-tools
