Dear Mr.Jonathan Smith:
   I'm sorry that there are some errors when I Run the code in colab, the log is as follow:

---------------------------------------------------------------------------

  the issue located at torch/distributions/distribution.py，and I don’t know how to fix it. I would be grateful if you could help me
