ValueError: Duplicate plugins for name projector

Question

Running tensorboard --logdir log_dir I get an error:

What can be a reason of this problem?

Answer 1

If you have two versions of tensorboard installed in your system,you need to uninstall one of them.

I was stuck this for hours but I finally fixed it using:

Worked like a charm: https://github.com/pytorch/pytorch/issues/22676

pip uninstall tb-nightly tensorboardX tensorboard
pip install tensorboard

Answer 2

I ran into the same issue after installing tensorflow==2.0.0-rc2. Uninstalling tensorboard did not help.

The culprit in my case was tb-nightly package:

#python3.7 -m pip list | grep tb
tb-nightly           1.15.0a20190806

After removing the package and reinstalling TensorFlow, tensorboard started to work properly.

Answer 3

I got same error, when I had two versions of tensorboard. In my Tensorflow 2.0 environmnet, except core Tensorflow lib, I could see other libs where installed from TF 1.14 version.

Do a pip list and see what versions of tensorflow libs are there. In my system I had

...
tensorboard                   1.14.0              
tensorflow-estimator          1.14.0              
tensorflow-gpu                2.0.0rc0            
tensorflow-serving-api        1.14.0              
termcolor                     1.1.0               
tf-estimator-nightly          1.14.0.dev2019080601
...

Here is what I did:

pip uninstall tensorboard
pip install --force-reinstall tf-nightly-2.0-preview

Answer 4

Run the following code if it shows two tensorboard installed on your system remove one.

import pkg_resources

for entry_point in pkg_resources.iter_entry_points('tensorboard_plugins'):
    print(entry_point.dist)

Answer 5

For Ubuntu users, go to: /home/$USERNAME/.local/lib/python3.8/site-packages/ or whatever path is displayed in the error. There you will see 2 folders with names something like this tensorboard and tensorboad-2.5.0.dist-info. Remove the second one.

Answer 6

One easy workaround for these sorts of issues is to call tensorboard via python -m tensorboard.main. For example, replace tensorboard --logdir ./model --port 6006 with python -m tensorboard.main --logdir ./model --port 6006. Much easier!

Answer 7

It took me a day to figure it out finally. In my case there were two folders for tensorboard at

** C:\ProgramData\Anaconda3\Lib\site-packages\ **

Keep the tensorboard folder for your preferred version and delete the other.

Answer 8

For me what worked was to uninstall the nightly build which is usually installed with pip since tf is usually installed with pip:

pip uninstall tb-nightly

then I installed tensorboard with conda

conda install -y -c conda-forge tensorboard

note I am using pytorch with tensorboard: https://pytorch.org/tutorials/recipes/recipes/tensorboard_with_pytorch.html

I did not need to install tensorflow but I did it in a second test since it was complaining about not having full features:

pip install tensorflow

since for some reason conda doesn't instlal tensorflow well (I tried it with conda-forge -c channel and it took to long to do anything).

Note you might need to uninstall more stuff as the answer https://stackoverflow.com/a/59408145/1601580:

pip uninstall tb-nightly tensorboardX tensorboard

suggested

Answer 9

I have faced the same problem. I found the problem creator was tb-nightly. I had installed it to resolve "Cannot start tensorboard in Jupyter Notebook" problem but after one day it arises "duplicate plugins for name projector" error.

I have tried pip uninstall tb-nightly but unfortunately it didn't work for me. The jupyter notebook was stacked in running.

Finally,I went to my site-packages folderC:\Users\User\anaconda3\Lib\site-packages and delete the tb-nightly folder,as well as from RecycleBin and it worked.

Answer 10

In short: You are very likely to have both tb-nightly and tensorboard installed. Nightly dependencies can easily mess thing sup.

Uninstall BOTH:

pip uninstall tb-nightly tensorboard

And install one that is compatible with your TF version (either tensorboard or tb-nightly):

pip install tensorboard          # or tb-nightly
