How to set up theano config

Question

I'm new to Theano. Trying to set up a config file.

First of all, I notice that I have no .theanorc file:

1. locate .theanorc - returns nothing
2. echo $THEANORC - returns nothing
3. theano.test() - passes ok

I'm guessing some default configuration was created wen i installed theano. Where is it?

Theano does not create any configuration file by itself, but has default values for all its configuration flags. You only need such a file if you want to modify the default values.

This can be done by creating a .theanorc file in your home directory. For example, if you want floatX to be always float32, you can do this:

echo -e "
[global]
floatX=float32
" >> ~/.theanorc

under Linux and Mac. Under windows, this can also be done. See this page for more details:
