    <p>I have recently tried to use pylearn2, a deep machin learning package for Python developed at University of Montreal. I've just installed it and tried to run a simple example, but it did not work.</p> <p>I have been using a pc with an Ubuntu 13.10 system, on which I found ipython installed. I have installed Theano and later pylearn2, by following this webpage instructions: <a href="http://deeplearning.net/software/pylearn2/" rel="nofollow">http://deeplearning.net/software/pylearn2/</a></p> <p>I have also modified the .bashrc file, as suggested</p> <p>I thought that everything went well, and then I tried this Quick start example: <a href="http://deeplearning.net/software/pylearn2/tutorial/index.html" rel="nofollow">http://deeplearning.net/software/pylearn2/tutorial/index.html</a></p> <p>I stopped at the first command:</p> <pre><code> python make_dataset.py </code></pre> <p>My terminal states:</p> <blockquote> <p>Traceback (most recent call last): File "make_dataset.py", line 14, in </blockquote> <p>Do you have any ideas on why it is not working?</p> <p>Do you why these errors occur?</p> <p>Thanks a lot</p> <p>EDIT: the 14 line is the first non-commented line of the file. It states</p> <blockquote> <p>from pylearn2.utils import serial</p> </blockquote>

    1. COYou need to show us the whole traceback, not just part of the first line. It would also help to either paste the code (at least around line 14) for `make_dataset.py`, or provide a direct link to the code you copied and pasted, instead of making us search for it.

    2. COMeanwhile: "Pylearn2 is still undergoing rapid development. Don’t expect a clean road without bumps!" I notice that the "install" instructions don't actually install anything, which means you'll only be able to run by either having your PWD set to the top-level pylearn2 directory (that is, `cd`ing into the tutorials isn't likely to work), or by modifying your `PYTHONPATH` to include that directory. Did you do either of those? Also, after modifying the .bashrc file, did you either `source ~/.bashrc` or create a new shell? If not, editing the file has no effect.

    3. COHi guys. A knowdledge colleague helped me and we solved this issue. The problem was that using the Numpy package was missin', and I've installed it through the command `sudo apt-get install python-numpy` on my Ubuntu pc. This was not a good idea, because that package version is antiquate. Instead, I should have used `pip install numpy`, and then 'pip install theano` and then `pip install pylearn`. That way, it worked.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
