pip installation fails

[Linda Marsh]

Hi this is the message that I get when I try to install pydicom.

[benphysics@localhost ~]$ pip install pydicom

[benphysics@localhost ~]$ python --version
Python 2.7.10 :: Anaconda 2.3.0 (32-bit)


My version of pip was installed by anaconda.

[benphysics@localhost ~]$ pip --version
pip 7.0.3 from /home/benphysics/anaconda/lib/python2.7/site-packages (python 2.7)


My operating system is Fedora 18
[benphysics@localhost ~]$ uname -r
3.11.10-100.fc18.i686.PAE


The computer is an old one and only 32 bit.

Can anyone help me with this?

Also what I really want to do is use pydicom with anaconda. Is there any chance of the developers distributing pydicom via binstar?

One small thing you can try is upgrading pip: 

pip install --upgrade pip

or for anaconda:

conda upgrade pip

Every so often when I get a weird error with pip, upgrading has always helped.

Lots of scientific users have anaconda and it is indeed awesome. Considering that pydicom is pure python though, there should be no problem using pip. There is also no inherent problem in using anaconda and "non-anaconda" packages together.
Conda has instructions about this as well.
