Could be... You'd have to look at the tracebacks to see what is failing. Check site-packages-3 and make sure you don't have any modules elsewhere named the same as one of the ones in the top level site-packages-3.
@augusto Yes, fortran codes run only by sage point of view, but you can use Pythonista to write fortran codes, test and use them when online, without using other ios apps that most likely are only able to send fortran code. Bye
Pythonista is a great way to work under developer mode. I am wanting to more scrape the Image but it is not supporting My Iphone to Itunes. Then I have installed Pythonista with the help of Apple Support Now it is working well to search and scraping of Image for my library.
