Answer 1

Managing packages in python is sometimes difficult. To avoid these problems, I recommend using Anaconda, which is a good python package and environment manager ( download here , and a 30-minute guide ).

Follow the official Anaconda installation instructions and select the default values ​​that will add Anaconda to your $ PATH and make Anaconda your default python interpreter. Then open a terminal and use the following commands:

• conda install pip six nose numpy scipy
• pip install theano

Then try running the script using anaconda.
