Operating system:Windows11
Slicer version:5.6
Expected behavior: run a python script using 3D slicer
Actual behavior: the 3D slicer source code give me a error
I run a python script that creates a valid dataset from the source data found on TCIA using 3D Slicer. [VS\_Seg/preprocessing/data\_conversion.py at master · KCL-BMEIS/VS\_Seg · GitHub](https://github.com/KCL-BMEIS/VS_Seg/blob/master/preprocessing/data_conversion.py)
but raise an error:
AttributeError: module ‘qt’ has no attribute ‘QProcess’
in Slicer\_5.6.2\lib\Slicer-5.6\qt-scripted-modules\DICOMLib\DICOMProcesses.py

Please provide the exact steps that lead to the issue you are having. Ideally, describe how to reproduce the issue with publicly available data.

Firstly, I open the python script as a Pycharm Project, and I change the Python Interpreter (System Interpreter) to the D:/Slicer5.6.2/bin/PythonSlicer.exe, the path in 3D Slicer archive.
Secondly, I run the python script aforementioned.
Then, I encounter the error
```auto

I use the public dataset from TCIA. The raw data includes
every patient’s **T1 and T2 DICOM files** ,
**RT\_Structure.dcm** **RT\_Dose.dcm** **RT\_Plan.dcm** and **metadata.csv**
and tumor segmentation label **contour.json**
and T1toT2 and T2toT1 registration matrices **inv\_T1\_LPS\_to\_T2\_LPS.tfm** or **inv\_T2\_LPS\_to\_T1\_LPS.tfm**
In proprecessing raw data, Firstly, **TCIA\_data\_convert\_into\_convenient\_folder\_structure.py** makes the raw data to a convenient folder structure which puts the every patient’s T1 folder and T2 folder
Secondly, **data\_conversion.py** converts the DICOM images and contour.json to NIFTI using the 3D Slicer. The error happens in this step.

PythonSlicer doesn’t have the application context needed to run all the DICOM options. See the warning here:
[https://slicer.readthedocs.io/en/latest/developer\_guide/python\_faq.html#what-is-the-pythonslicer-executable](https://slicer.readthedocs.io/en/latest/developer_guide/python_faq.html#what-is-the-pythonslicer-executable)
You probably can just run the regular Slicer application instead.

Thanks a lot!! I run the data\_conversion.py in the Python Console 3D Slicer application. It works!! Thanks again.
