Dear Amber users,

I did installation of both serial and parallel version of Amber18 without
any error. Serial test passed with 0 error. However, when ran the parallel
test I got an error saying "Could not import Amber Python modules!".
In my knowledge I correctly set the path for Python still getting the same
problem. I did the configuration in the following way.

./configure --with-python
/home/external/cbs/sunitap/softwares/Python-3.6.0/bin/python -mpi gnu

Please help me where I am going wrong. Pls see the excerpts pasted below.
I searched the mailing list and tried all the possible suggestions. Still
getting the same problem.

System was having older python 2.6 so installed Phython3.6 locally and set


Thanks in advance.

*Error:* Could not import Amber Python modules!
   Probably your Amber Python environment was not set up correctly.

We recommend adding the line:

   test -f /home/external/cbs/sunitap/softwares/amber18/amber.sh && source
/home/external/cbs/sunitap/softwares/amber18/amber.sh (sh/bash/zsh)
   test -f /home/external/cbs/sunitap/softwares/amber18/amber.csh && source
/home/external/cbs/sunitap/softwares/amber18/amber.csh (csh/tcsh)

to your login shell resource file (e.g., ~/.bashrc or ~/.cshrc).
make[1]: *** [test.parallel] *Error 1*
