Hi David, thanks for the reply.

With cmake instead of cmake3 on CentOS 7 for AmberTools20? I am trying to clarify if the key is re-installing AmberTool20 or the key is re-building AmberTool20 separately with cmake...

I used to use cpptraj a lot...not sure if it utilizes the function of pytraj....


Thanks,

This problem comes up a lot. As best I can tell, "older" miniconda python installations are missing something that is needed to build pytraj. The current install procedure (in AmberTools20) seems to be working.

I'm cc-ing to Hai in case he has any way of debugging this problem. The build scripts don't fail (although there may be some error message hidden in there), but the pytraj module is not found.

If you try a fresh install of AmberTools20 using cmake, I think you should get a functioning pytraj.

(Of course, if you are not planning to use pytraj, you can ignore the
failure....)

...good luck....dac
