Projector tab doesn't appear

Hi, I’ve been following the tutorial for Visalizing models, data, and training with Tensorboard and got stuck at section 4 of the tutorial - Adding a “Projector” to TensorBoard.

After I run the code and refresh the Tensorboard page at http://localhost:6006/ , a Projector tab doesn’t appear. When I choose Projector from the drop down menu on the right side, I get an empty page. Then, in the cmd window I get the following error:

TensorFlow installation not found - running with reduced feature set.

I’m running Pytorch 1.3.1 with Tensorboard 2.0.0 in a conda environment.

Any idea why this is happening?

Same here the Projector Tab does not appear, but I can choose it from the drop down menu and seems to be working from there.

I got the same problem, anyone managed to solve this?

EDIT: Using Pytorch 1.4.0 and installing tensorboard nightly (2.3.0a I believe I installed) then it worked perfectly for me. Might be worth checking if you run into the same issue.

I have this problem too.
My solution is to install tensorflow as backend support.

I had this problem as well, and the solution is to restart tensorboard in the terminal
