ImportError: No module named dicom

Hi,
I get the following error trying to load dicom files with nibabel. The files are from a Siemens Skyra.

data,affine,bvals,bvecs = read_mosaic_dwi_dir(dcm_dir)
Traceback (most recent call last):

File "<ipython-input-8-40e949d760f1>", line 1, in <module>

File "/home/mje/Toolboxes/anaconda/lib/python2.7/site-packages/nibabel/nicom/dicomreaders.py", line 89, in read_mosaic_dir

File "/home/mje/Toolboxes/anaconda/lib/python2.7/site-packages/nibabel/nicom/dicomwrappers.py", line 52, in wrapper_from_file
  import dicom

ImportError: No module named dicom

I have pydicom install, any ideas what the problem might be?

best wishes,

What do you get for:

python -c 'import dicom'

How did you install pydicom? Is it possible that you installed it with pip and the pip you used was not the one from Anaconda?

I am guessing it is due to pydicom 1.0 being installed. The module name changes from "dicom" to "pydicom": https://github.com/darcymason/pydicom/wiki/Porting-to-pydicom-1.0

[moloney]

Hmm, sorry for the noise. I guess 1.0 isn't quite out yet.

@matthew-brett I get:
python -c 'import dicom'
Traceback (most recent call last):
File "", line 1, in
ImportError: No module named dicom

@moloney yes I have pydicom 1.0 from git installed.

I tried with the pip version as well, but that didn't work either. But it was the anaconda pip, so it sounds like that is why.

[moloney]

The code needs to be update to work with pydicom 1.0, but should work with 0.99 and earlier.

thanks, I fixed the pydicom version and it works.

I made a new issue for this, just so we don't forget: #351
