spyder error with pydicom installed

[Soren Christensen]

Hi,

 I am using anaconda2 with spyder 3.2.3.

This works fine - until I install pydicom 0.9.9.  I am installing pydicom using python setup.py install (pip does not hold newest version, so I am getting it from github and installing this way).

When I then start spyder I get the below error. I see a spyder gui after that, but a warning about a javascript error and then a segfault.

If I delete the pydicom package (anaconda2/lib/python2.7/site-packages/pydicom-1.0.0a1-py2.7.egg) then spyder works again. 

Why is spyder reading anything from the pydicom folder?  It seems to be a library conflict, but I don't understand how it takes place.

Thanks!

Soren

Hi,

Spyder has a plugin to automatically read dicom files when pydicom is installed:

https://github.com/spyder-ide/spyder/blob/3.x/spyder_io_dcm/dcm.py

So I think that's causing the error you reported.

Please remove the egg you installed and run these commands:

    conda install numpy
    conda install -c conda-forge --no-deps pydicom

That should solve your problem.


Cheers,
Carlos

Thanks this worked. Issue seems to be when I install from the github build directly.
