Hello everyone, thanks for reporting the issue. Which version of TensorFlow have you installed? This can happen if you have tb-nightly installed on your virtualenv then install tensorboard==1.12.x.

Like @kenpachiii put, can you try to delete tensorboad directory in site-packages (Location in pip show tensorboard) then pip install tensorboard==1.12?

I got it working with the following steps:

pip uninstall tensorflow
pip uninstall tensorboard
go to site-packages and remove tensorflow/tensorboard folders
Reinstalled tensorflow - pip install [whatever wheel package]

You can find the wheel packages here for specific install types: https://www.tensorflow.org/install/pip

Note: I only stated the specific wheel package because that’s what I did.

I know this doesn’t explain the ‘why’ of the issue but it got things going for me. Hope it helps!

Thanks, it seems the problem from tb-nightly. I uninstalled tb-nightly and reinstalled the tensorboard. Finally, it works!!!
