ArgumentError in downsmapling

[oooo1114]

Hi, Kyle,
I am trying the demo for scatter correction "d31_scatter_correction.py".
But the code run into an error in line 178 when down-sampling the data.
The error information is listed below:

Exception has occurred: ArgumentError
argument 2: <class 'TypeError'>: array must have data type int32
  File "d31_scatter_correction.py.py", line 178, in <module>
    g_dn = leapct_LR.down_sample_projections([1,downSampleFactor,downSampleFactor],g)
ctypes.ArgumentError: argument 2: <class 'TypeError'>: array must have data type int32

Any suggestions?
Thanks.

The script runs fine for me. Did you make any changes to it? What version of LEAP are you running?

[oooo1114]

v1.19, I think the error may be related to my environment since you can run.

It seems strange to me that your python environment would cause this issue. Have you changed anything in that script?

[oooo1114]

No. It might be related to other packages in the environment. Never-mind, I use torch interpolate instead. Thanks.

OK, just make sure you update the LEAP CT parameters accordingly.
