Python 2.7 Error

[jonesnat]

Describe the bug I am getting a PyType_GetFlags error when I type this command: mdl = getBrainAgeModel( tempfile() ) in R.

Below is the error message: Error: PyType_GetFlags - /usr/lib64/python2.7/config/libpython2.7.so: undefined symbol: PyType_GetFlags

To Reproduce Steps to reproduce the behavior:

1. Load Python 3.10 and R 4.3.1
2. Start R session
3. Load required libraries in R: brainAgeR, ANTsR, tensorflow, keras
4. Type filename = system.file("extdata", "test_image.nii.gz", package = "brainAgeR", mustWork = TRUE)
5. Type img = antsImageRead( filename )
6. Run getBrainAgeModel command: mdl = getBrainAgeModel( tempfile() )
7. See error

Expected behavior Not get the error message

Desktop (please complete the following information):

• OS: RHEL8
• High performance computing cluster

Additional context Since Python2.7 is deprecated is there a plan to update to Python3?

Can you provide more context on the interplay between R and Python here - What do you mean by "Load Python 3.10.." ? Are you calling R from within Python, or vice-versa? I don't understand why you would get a Python error in ANTsR otherwise.

And in any case - we don't support Python2.7 in ANTsPy anymore.
