Try installing the g++
compiler.
Python is rather slow, so for performance-critical parts you need a compiled language such as C++.
Frage
After I installed Theano I tried to run it but got following error message:
WARNING (theano.configdefaults): g++ not detected! Theano will be unable to execute
optimized C-implementations (for both CPU and GPU) and will default to Python
implementations. Performance will be severely degraded.
Why?
