colab fatal: reference is not a tree about notebook HOT 5 CLOSED

Thanks for the report.
@pyf98, can you fix it?

Actually, I encountered the same issue, but in my case, the following steps were executed smoothly regardless of this error.

Hi @jawadatgithub @sw005320 May I know where you ran this notebook? I tested this code block locally and on Colab, but didn't see this error.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 9cff98a update minor bugs

The error happened in Colab:
https://colab.research.google.com/github/espnet/notebook/blob/master/espnet2_recipe_tutorial_CMU_11751_18781_Fall2022.ipynb#scrollTo=St7lke2P0GUP

@sw005320 Yes next steps executes but Espnet building fails, hence nothing of more later steps will work.

I just retest again and I am not able to get into what @pyf98 getting:

The notebook originally can be found in:
https://github.com/espnet/notebook/blob/master/espnet2_recipe_tutorial_CMU_11751_18781_Fall2022.ipynb

Note that I also test without "--depth 5", but didn't work. Also I checked the commits tree and tried many which belongs to the branch 2022fall_new_task_tutorial , and all failed.

from notebook.

@jawadatgithub There are two notebooks: one for the recipe and the other for the new task. Your first post was using the new task one, but the latest post is about the recipe one.

For the recipe tutorial, I think any later commit should work. It is pretty straightforward.

The new task tutorial uses a separate branch which should work without this error, as shown in my previous post.

Thanks for the help, the issue caused by Colab not being able to save changes since the notebook belong to github repo, hence I had to make a copy into my google drive "this done automatically by clicking on "can't save changes" appears on top in Colab UI.
