i was trying to fix my GPU to use with Theano, i had a problem with the liblas.so but python worked good, but when i did

sudo ldconfig /usr/local/cuda/lib64

(i got this from internet, bad idea, i know) now i have problems with Python:

python cifar10.py 

    /home/franco/.local/lib/python2.7/site-packages/numpy/lib/utils.py:254: FutureWarning: Numpy has detected that you (may be) writing to an array returned

    by numpy.diagonal or by selecting multiple fields in a record

    array. This code will likely break in the next numpy release --

    see numpy.diagonal or arrays.indexing reference docs for details.

    The quick fix is to make an explicit copy (e.g., do

    arr.diagonal().copy() or arr[['f0','f1']].copy()).

      ai = a.__array_interface__

    Traceback (most recent call last):

      File "cifar10.py", line 46, in <module>

        import theano

      File "/home/franco/.local/lib/python2.7/site-packages/theano/__init__.py", line 103, in <module>

        import theano.sandbox.cuda

      File "/home/franco/.local/lib/python2.7/site-packages/theano/sandbox/cuda/__init__.py", line 448, in <module>

        from . import opt, dnn

      File "/home/franco/.local/lib/python2.7/site-packages/theano/sandbox/cuda/opt.py", line 40, in <module>

        from theano.sandbox.cuda.cula import gpu_solve

      File "/home/franco/.local/lib/python2.7/site-packages/theano/sandbox/cuda/cula.py", line 1, in <module>

        import pkg_resources

    ImportError: No module named pkg_resources

Now i cant use Python. How can i fix this ?

July 2018 Update

Most people should now use pip install setuptools (possibly with
sudo).

Some may need to (re)install the python-setuptools package via their
package manager (apt-get install, yum install, etc.).

This issue can be highly dependent on your OS and dev environment. See
the legacy/other answers below if the above isn't working for you.

Explanation

This error message is caused by a missing/broken Python setuptools
package. Per Matt M.'s comment and setuptools issue#581,
the bootstrap script referred to below is no longer the recommended installation
method.

The bootstrap script instructions will remain below, in case it's
still helpful to anyone.

Legacy Answer

I encountered the same ImportError today while trying to use pip.
Somehow the setuptools package had been deleted in my Python
environment.

To fix the issue, run the setup script for setuptools:

wget https://bootstrap.pypa.io/ez_setup.py -O - | python

(or if you don't have wget installed (e.g. OS X), try

curl https://bootstrap.pypa.io/ez_setup.py | python

possibly with sudo prepended.)

If you have any version of
distribute, or
any setuptools below 0.6, you will have to uninstall it first.*

See Installation
Instructions
for further details.

* If you already have a working distribute, upgrading it to the
"compatibility wrapper" that switches you over to setuptools is
easier. But if things are already broken, don't try that.
