[FEAT EXTRACTION] ERROR: Filter does not support casting from casting 32-bit float to 32-bit unsigned integer

When conducting feature extraction using Pyradiomics, I encountered this error:

Exception thrown in SimpleITK Cast: /tmp/SimpleITK/Code/BasicFilters/src/sitkCastImageFilter.cxx:94:
sitk::ERROR: Filter does not support casting from casting 32-bit float to 32-bit unsigned integer

I then tried doing feature extraction without a configuration parameter file but encountered the same error.

To Reproduce Steps to reproduce the behavior:

# Import libraries 
import SimpleITK as sitk
from radiomics import featureextractor

image = sitk.ReadImage(image_filepath)
label = sitk.ReadImage(label_filepath)
extractor = featureextractor.RadiomicsFeatureExtractor()
extractor.execute(image, label, voxelBased = False)

Version (please complete the following information):

• OS: Linux on Google Colab
• Python version: 3.10.12
• PyRadiomics version 3.0.1
• SimpleITK version 2.2.1
• Numpy version 1.22.4

Additional context The image file was a PET image and the mask was a c1 segmentation file generated from SPM. The dimensions of the image and the mask match perfectly, and the mask contains

Sorry it was just a bug in my code. Instead of inputting the filename as a string, I used the list of filenames as input, resulting in the above error.

I will close this issue now.
