Trying to train the model and got this error

I was trying to execute "model_train.ipynb" in google colab, all the above steps were executed without any problem in the model_train.ipynb but at the time Training the model I got this error as below

Something went wrong

Or can you please provide pre-trained model link to download because in readme file it's wrong
Thank you in Advance for helping :)
