  • cd pytraj
  • python ./setup.py install
• if using specific verion (go to releases to check the most updated and stable version)

  • (unzip and cd to pytraj)
  • python setup.py install
• Done
• Simple test: python -c 'import pytraj as pt; pt.run_tests()'

Note: Possible failure: can not find netcdf.h file. Make sure to install netcdeflib or specify its include path

2. Using pip

• not yet supported. Use "git" or "conda"

3. Using conda

• conda install -c pytraj pytraj-dev

4. run small test after installing

python -c 'import pytraj as pt; pt.run_tests()'

if you install via github, you will get full test runs

• cd tests
• python ./python ./run_all_and_find_fails.py

Possible errors:

1. "ImportError: libcpptraj.so: cannot open shared object file: No such file or directory"

you need to add libcpptraj.so to LD_LIBRARY_PATH
