Problem with INVALID_KEYWORD_BEHAVIOR

[pearsomark]

Hi,
I am using V2.3.1 to parse files with a private tag sequence that contains invalid tags so I get warnings like this:

/usr/lib/python3/dist-packages/pydicom/valuerep.py:290: UserWarning: Invalid value for VR UI: '\x03'. Please see <https://dicom.nema.org/medical/dicom/current/output/html/part05.html#table_6.2-1> for allowed values for each VR.

I can still process the invalid tags so I just want to suppress the messages. I tried using pydicom.config.INVALID_KEYWORD_BEHAVIOR = 'IGNORE' in my program but the warnings are still printed.

I tried the same thing in repl and the warnings are only suppressed if the config is changed after loading the dataset.

Any suggestions on how to fix this?

I tried using pydicom.config.INVALID_KEYWORD_BEHAVIOR = 'IGNORE' in my program but the warnings are still printed.

The INVALID_KEYWORD_BEHAVIOR doesn't apply here - that is for something like: ds.NotAKeyword, an unknown DICOM keyword. The error is related to the value itself - here a binary value for what should be a restricted character set (text) value for UI.

You might try

config.settings.reading_validation_mode = config.IGNORE

But I'm not certain that will work. As the documentation says, it still may warn due to encoding issues.

Thanks, that addition does suppress the warning messages in this case.

I also added the private elements to the dictionary which removed 99% of the warnings.
