I finally was able to install ipython on my Windows 7 PC and it runs without any errors. The problem is that I used to code in ipython but in MAC. Now that I am trying to upload my previous notebooks I receive the following error:
Unreadable Notebook: MyFile.ipynb Unsupported nbformat version 4
I found this answer for my question but unfortunately that is not for windows and did not resolve my problem. It is worth to mention:
ipython --version
produces: 2.3.1
Any help or comment on this is much appreciated.
Thanks
