Wrong message in extracting radiomics about 64-bit float

When I extracted from 3D segment, some could be extracted but some failed, the wrong messgae is as follows:

[2020-05-22 21:40:45] E: radiomics.script: Feature extraction failed!

Your pixeltype is a vector of 64-bit float, i.e. a color image. PyRadiomics is designed to extract from gray-scale images. What is the input data you are using? You could consider extracting a single color channel, or taking the mean across color channels.

I used MRI image. It was a gray-scale image.
