I am trying to run the demo code from [Demo\_tensorboard.ipynb](https://colab.research.google.com/gist/sayakpaul/5b31ed03725cc6ae2af41848d4acee45/demo_tensorboard.ipynb) so that I can learn more about the use of Tensorboard in combination with W&B. Unfortunately this code throws this warning:

WARNING When using several event log directories, please call `wandb.tensorboard.patch(root_logdir="...")` before `wandb.init`

When I implement the suggested change with:

`wandb.tensorboard.patch(root_logdir="./logs/debug")`

I get the following warning:  
Found log directory outside of given root\_logdir, dropping given root\_logdir for event file in i:\tinyml\tiny\_cnn\wandb\run-20221016\_205607-22b9tlzf\files\train

So my questions is: What is a suitable root\_logdir for Tensorboard?

Thanks for your support.

Hi Susanne,

Thanks for writing in! The `root_logdir`argument is the path to the root of all tfevent files, so you can use the wandb project folder (in this case I think it is `I:/tinyml/tiny_cnn`). Could you try if setting this solves the issue?

Best,  
Luis

Setting root\_logdir = os.getcwd() actually solved the issue.

Thanks for the support.
