Yes, my python is in version 3.6
phtran@X230:~/workingspace/InsightToolkit-5.0.1/build$ grep PYTHON_EXECUTABLE CMakeCache.txt
PYTHON_EXECUTABLE:FILEPATH=/usr/bin/python
//ADVANCED property for variable: PYTHON_EXECUTABLE
PYTHON_EXECUTABLE-ADVANCED:INTERNAL=1
phtran@X230:~/workingspace/InsightToolkit-5.0.1/build$ python --version
Python 3.6.8

But I still got errors:
/home/phtran/workingspace/InsightToolkit-5.0.1/build/Wrapping/Generators/Python/PyBase/ITKPyBasePython.cpp: In function ‘void init_ITKPyBasePython()’:
/home/phtran/workingspace/InsightToolkit-5.0.1/build/Wrapping/Generators/Python/PyBase/ITKPyBasePython.cpp:3864:52: error: void value not ignored as it ought to be
