I am trying to run this code in jupyter notebook. this is the error that I am getting. If I run the code in simple python environment it runs perfectly. Any suggestions???

It's strange that it would work perfectly in a Python virtual environment but not in a Jupyter Notebook. I'm assuming you installed and launched your Jupyter Notebook from your Python virtual environment? You might want to double-check that.

My only suggestion is that this is a dlib error. The predictor would be your facial landmark predictor which is a dlib function. If you still have the issue I would suggest opening an issue on the dlib GitHub page.
