import failure with pydicom 3.x in dicomparser.py

[sjswerdloff]

The API in pydicom 3.x has changed with respect to 2.4.x (not surprising, given major version bump).

I believe the failure is happening in dicomparser.py

try:
    from pydicom.dicomio import read_file
    from pydicom.dataset import Dataset, validate_file_meta
    from pydicom.pixel_data_handlers.util import pixel_dtype
except ImportError:
    from dicom import read_file
    from dicom.dataset import Dataset

where the first try at importing (presumably pydicom 2.x API) fails, it goes to the except clause, and then reports not finding "dicom".

Is there a preference for trying to cascade the import attempts with a new starting API that matches pydicom 3.x or just pin pydicom in the range >=2.4 , <= 3.0?

I'll give the former a try if there's interest.

Hi Stuart, this was updated (issue #380, pr #384 and related) so that dicompyler-core is pinned for pydicom >=2.4,<4.0.

not released yet on PyPI... ok. I've pinned pydicom to 2.4.4 in the branch on the project I'm working on (OnkoDICOM), but I'll set the version for dicompyler-core to be ready for 0.5.7 when it becomes available (and then I'll try to unpin pydicom).
