In the current nightly binary, neither `import dicom` nor `import pydicom` work. Is there a new way to import pydicom? ---

Same runtime issue for DICOMPatcher, so at least it’s not just me… ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/f/4/f44350c95b015be310fa19fe4b6aba20bec110e2.png) ---

Thanks for reporting. There have been several commits lately moving to standardized upstream python sources (e.g. see [this](https://github.com/Slicer/Slicer/commit/f348d6f5bf977204e726146ec5b3f46143ff9109) and [this](https://github.com/Slicer/Slicer/commit/fa6c90c5bf3dc9def76a144d8bb0e734e1bdbfea)). I suspect it may take a few days for the packaging to settle out. ---

The DICOM packages are missing even from the build tree. ---

I’ll take a look. Thanks for the report! ---

It has broken again. I’m taking a look at the project dependencies again… ---

OK. To fix the issue, I’ve reverted the latest python package related commit ([https://github.com/Slicer/Slicer/commit/47a8e5b90fe7ca2ce2e3834a8f2b1019413907e5](https://github.com/Slicer/Slicer/commit/47a8e5b90fe7ca2ce2e3834a8f2b1019413907e5) ). ---

Can anyone provide any sort of support for what I asked about in [https://github.com/Slicer/Slicer/pull/1231#issue-328045247](https://github.com/Slicer/Slicer/pull/1231#issue-328045247)? ---

1246 is merged. Do you still need help with [https://github.com/Slicer/Slicer/pull/1231#issue-328045247](https://github.com/Slicer/Slicer/pull/1231#issue-328045247)? ---

The python dependencies still don’t seem to be handled as I would expect. Most fixes have been trial and error so far.
