Description

Python is a programming language.

Running Program

Also refer to Running Jobs on Sapelo2

There is no default python command on the system. The OS comes with a default /usr/bin/python2 (v. 2.7.18) and a default /usr/bin/python3 (v. 3.6.8). Scripts that have the first line:

#!/usr/bin/python

will not work on Sapelo2 (with the Rocky 8 OS). We recommend that you change this line to

#!/usr/bin/env python

and load one of the Python modules before running the script.

We have a set of Python versions installed on Sapelo2 via environment modules. To find out which Python modules are installed, please run the following command on the cluster:

ml spider Python

For example, this output could look like this:

ml spider Python

About Python packages

Some common third-party Python packages are installed individually as separate modules on the cluster.

numpy, scipy, pandas

The numpy, scipy, pandas, mpi4py, mpmath, and deap packages are installed in SciPy-bundle module:

ml spider SciPy-bundle    

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
  SciPy-bundle:
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    Description:
      Bundle of Python packages for scientific software

     Versions:
        SciPy-bundle/2021.10-foss-2021b-Python-2.7.18
        SciPy-bundle/2021.10-foss-2021b
        SciPy-bundle/2021.10-foss-2022a-Python-2.7.18
        SciPy-bundle/2022.05-foss-2022a

----------------------------------------------------------------------------------
  For detailed information about a specific "SciPy-bundle" package (including how to load the modules) use the module's full name.
  Note that names that have a trailing (E) are extensions provided by other modules.
  For example:

     $ module spider SciPy-bundle/2022.05-foss-2022a
----------------------------------------------------------------------------------

Note that, when you load SciPy-bundle module, a specific version of Python that the package is built for will be loaded at first. This means that you don't have to load the Python module separately from loading SciPy-bundle module. For example:

• Python/3.9.6-GCCcore-11.2.0 will be automatically loaded when SciPy-bundle/2021.10-foss-2021b is loaded.

• Python/3.10.4-GCCcore-11.3.0 will be automatically loaded when SciPy-bundle/2022.05-foss-2022a is loaded.

• Python/2.7.18-GCCcore-11.2.0 will be automatically loaded when SciPy-bundle/2021.10-foss-2021b-Python-2.7.18 is loaded.

• Python/2.7.18-GCCcore-11.3.0 will be automatically loaded when SciPy-bundle/2021.10-foss-2022a-Python-2.7.18 is loaded.

matplotlib

The matplotlib package is installed in matplotlib module.

ml spider matplotlib

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
  matplotlib:
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    Description:
      matplotlib is a python 2D plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments across platforms. matplotlib can be used in python
      scripts, the python and ipython shell, web application servers, and six graphical user interface toolkits.

     Versions:
        matplotlib/2.2.5-foss-2021b-Python-2.7.18
        matplotlib/2.2.5-foss-2022a-Python-2.7.18
        matplotlib/3.4.3-foss-2021b
        matplotlib/3.5.2-foss-2021b
        matplotlib/3.5.2-foss-2022a

----------------------------------------------------------------------------------
  For detailed information about a specific "matplotlib" package (including how to load the modules) use the module's full name.
  Note that names that have a trailing (E) are extensions provided by other modules.
  For example:

     $ module spider matplotlib/3.5.2-foss-2022a
----------------------------------------------------------------------------------

Same as SciPy-bundle, when you load matplotlib module, a specific version of Python that matplotlib is built for will be loaded at first, which means you don't have to load the Python module separately from loading matplotlib module. For example:

• Python/3.9.6-GCCcore-11.2.0 will be automatically loaded when you load matplotlib/3.4.3-foss-2021b or matplotlib/3.5.2-foss-2021b.

• Python/3.10.4-GCCcore-11.3.0 will be automatically loaded when you load matplotlib/3.5.2-foss-2022a.

• Python/2.7.18-GCCcore-11.2.0 will be automatically loaded when you load matplotlib/2.2.5-foss-2021b-Python-2.7.18.

• Python/2.7.18-GCCcore-11.3.0 will be automatically loaded when you load matplotlib/2.2.5-foss-2022a-Python-2.7.18.

Biopython

The Biopython package is installed in Biopython module.

ml spider biopython

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
  Biopython:
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    Description:
      Biopython is a set of freely available tools for biological computation written in Python by an international team of developers. It is a distributed collaborative effort to develop Python libraries
      and applications which address the needs of current and future work in bioinformatics. 

     Versions:
        Biopython/1.79-foss-2021b
        Biopython/1.79-foss-2022a

----------------------------------------------------------------------------------
  For detailed information about a specific "Biopython" package (including how to load the modules) use the module's full name.
  Note that names that have a trailing (E) are extensions provided by other modules.
  For example:

     $ module spider Biopython/1.79-foss-2022a
----------------------------------------------------------------------------------

Same as above SciPy-bundle and matplotlib, when you load Biopython module, a specific version of Python that the package is built for will be loaded at first. You don't have to load the Python module separately from loading Biopython module. For ecample:

• Python/3.9.6-GCCcore-11.2.0 will be automatically loaded when Biopython/1.79-foss-2021b is loaded.

• Python/3.10.4-GCCcore-11.3.0 will be automatically loaded when Biopython/1.79-foss-2022a is loaded.
