I think that should be a problem in line 3302 "confmat = ConfusionMatrix(task="multiclass", num_classes=len(class_names))\n". I updated the double quote task="multiclass" to a single quote task='multiclass' "confmat = ConfusionMatrix(task='multiclass', num_classes=len(class_names))\n" and I can open it in Google Colab afterward.
