I installed the latest version of the ROOT and python. I need to run the python project with Keras API. However, the following crash had happened while I tried to run my python script:
File “keras0_Binary.py”, line 22, in
TMVA.PyMethodBase.PyInitialize()
AttributeError: <namespace cppyy.gbl.TMVA at 0x7ff6c1e6d630> has no attribute ‘PyMethodBase’. Full details:
type object ‘TMVA’ has no attribute ‘PyMethodBase’
‘TMVA::PyMethodBase’ is not a known C++ class
‘PyMethodBase’ is not a known C++ template
‘PyMethodBase’ is not a known C++ enum
I’ve installed all the packages like NumPy, SciPy, etc., and build the ROOT with a flag pointing to the python executables.
I’m a beginner in the field of ML application in HEP, any tips and help would be highly appreciated.
Sorry for the late reply. It looks like you have built ROOT without support for pymva. Can you try configuring with cmake . -Dtmva-pymva=On and check in the log if all Python and bumpy packages are correctly found.
I’ve tried cmake . -Dtmva-pymva=On and got the following message in the log:
TMVA: Numpy or Python development package not found for python /usr/bin/python3. Switching off tmva-pymva option
I’m confused since I installed these packages even using conda to allow system to find all the required packages easily. (If I’m correct at that point).
