Tensorboard loading forever/ not loading in vs code nor in terminal

Goal: I want to launch the tensorboard dashboard and visualize the loss/metrics in the scalars tab from a generated tfevents file there.

Setup: In a conda environment, with python=3.8.5, with only these packages installed (I created a fresh environment to test the issue, initial code environment used python 3.9):

Outcome: I have an already generated tfevents file in the subfolder runs. When I use vscode, the now vscode integrated tensorboard is loading until timeout. First, I thought its an issue with vs code only...

But I tried to launch tensorboard via the integrated terminal (cmd prompt) with: tensorboard --logdir=runs or tensorboard --logdir="C:workspace\runs" --host localhost --port 6006.

Whether in the interactive window in vscode or on http://localhost:6006/, in all cases tensorboard only opens with the orange header, with a blank page (see image below), loading eternally...

What am I doing wrong here? Its similar to this, but the solution there is not helpful. Thanks a lot!

EDIT: Thanks to @LzZ, it now magically works even with the above old environment when using the integrated terminal commands but the launch via the command palette still doesnt work in vscode

EDIT2: Somehow its back to NOT working again in no environment. Something must have unclogged everything yesterday. Now its back to not working...

EDIT3: Update: It now works when first calling tensorboard --logdir dir in the integrated terminal. Only afterwards, the %load_ext tensorboard and %tensorboard --logdir dir also work in vscode itself.

when opening tensorboard in a browser or also integrated in vs code this appears

A bit of an old thread but ran into similar problem recently so VS code seems to still choke on tensorboard startup exceptions by hanging up which is not great!

A good way to troubleshoot and fix is to try and run tensorboard from the command line on a terminal in the same virtualenv as you're using in VS code. something like:

tensorboard --logdir somedir/

You will most likely run into some exception. In my case for example it was something like:

...
    raise ValueError(
ValueError: Duplicate plugins for name projector

Which suggested some kind of duplicate installation scenario. This was quickly resolved when I realized I did indeed install a nightly version of tensorboard (released under the package name tb-nightly) which apparently does not play nice with VS Code installing its own tensorboard! so I had to resolve by uninstalling and force reinstalling the regular tensorboard. a CLI such as the following would do:

pip uninstall tb-nightly
pip install -U --force-reinstall tensorboard

depending on the exact duplicate packages you might have installed details might be different, but more often than not this will be it.

Try running pip uninstall torch-tb-profiler to uninstall the plugin.

You should then be able to run tensorboard --logdir [name of log directory] to get tensorboard running.

I've also experienced such issue after installed the PyTorch Profiler Tensorboard plugin, which was recommended by python extension. What I've done to solve this issued is to re-install my conda environment and not to install the PyTorch Profiler Tensorboard plugin.
