Keras on Raspberry Pi

[vitel...@gmail.com]

I'm trying to install Keras on Raspberry Pi 3 model B whit no success. The OS is Raspbian and python 2.7. I installed Theano with no problem. Should I change OS to Ubuntu Mate or Snappy Ubuntu Core? Any suggestion?

How are you doing it? What is your problem?

[Matias Valdenegro]

Describing the problem appropriately (including code and/or complete error
messages) is the first step into solving it.

I'm not able to install keras with setup.py install execution neither  with pip command. There are no requirements.

What is the output of those commands? Any error messages? Put them here.

Sorry, I was not in the office yesterday. However it was a connection problem. I tried again this morning and no problem occurred.

I'm also trying to install Keras on Raspberry Pi 3 model B with no success.
Which step and command did you use to succeed?

I tried:

pip install git+git://github.com/Theano/Theano.git

But that did not worked. If that had worked I would have continued with:

pip install git+git://github.com/fchollet/keras.git

What happened? What error did you get?

[kens...@gmail.com]

"What happened? What error did you get? "

After command:

pip install git+git://github.com/Theano/Theano.git

I got:

UnicodeDecodeError: 'ascii' codec can't decode byte Oxe2 in position 72: ordinal not in range(128)

This is not the only message you got, only the last one. You should include the whole output from pip.

Still the message is cut but you can clearly see that pip is complaining about not finding Python.h. Install it with whatever package manager your distribution uses, likely python-dev on debian/ubuntu systems.

Many thanks for your support!

I installed python.h from (python-dev).

I then tried install Theano again but it still doesn't work:

The error is telling you that it doesn't have permissions to install numpy, so you are trying to override the system's Python. That is a very bad idea, use a virtualenv instead.

I'm a newbie in Python so I just checked out what "a virtualenv" is.

http://docs.python-guide.org/en/latest/dev/virtualenvs/

I now know how to install it:

pip install virtualenv

 

But how will I use it?

I'm not a programmer....

2. I found that to begin using the virtual environment, it needs to be activated:

$ source venv/bin/activate

Can I just activate it and then start to install Thenao?

>>pip install git+git://github.com/Theano/Theano.git

Then deactivate it when it is done?

3. If you are done working in the virtual environment for the moment, you can deactivate it:

$ deactivate

Just use pip install --user theano, and install all packages with --user

Somewhere a script is using multi-byte characters without declaring the encoding like so:

#!/usr/local/bin/python

import os, sys
