a problem in colab
when I run it in colab, I faced a problem like this
Can you tell me how to solve it?
Sorry for the inconvenience you're facing. I have just checked the Colab, and you're right. Thank you for notify me.
There must be someone who forgot to create a Copy of the Notebook BEFORE running the code. So my original Colab folder has been modified, which caused the issue.
I'll reply to this issue as soon as the Colab is fixed. Please stay tuned and check back later.
In the meanwhile, you can run the code on your local machine. Thanks for your patience!

any updates?
Hello all, I'm sorry to say that I am busy with other works recently, so fix the Colab will not be my top priority. But I'll strive to get it worked by the end of this month. Please stay tuned, and once again, you can run it in your local machine in the waiting time. Have a good day!
(Sorry, I accidentally close this issue :v)
We do not have plan to maintain Google Colab anymore. Sorry for the inconvenience.
