Cannot create a new Python notebook

When I try to create a new Python 2 notebook (only available option for me) in the path caffe2/tutorials, I get the following error in jupyter: Creating Notebook Failed An error occurred while creating a new notebook. Unexpected error while running post hook save: [Error 2] The system cannot find the file specified

However, I am able to create a new python notebook somewhere else.

My configuration: Python 2.7 I installed jupyter using pip.

Below the console output [I 00:29:12.068 NotebookApp] Serving notebooks from local directory: D:\Yeverino\git_projects\caffe2_tutorials [I 00:29:12.069 NotebookApp] 0 active kernels [I 00:29:12.069 NotebookApp] The Jupyter Notebook is running at: [I 00:29:12.069 NotebookApp] http://localhost:8888/?token=62e280100ce0984423306bb702755a42b9523af35656aa55 [I 00:29:12.069 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
