-Thats it. The /opt/gridware python comes with nose, ipython, and numpy. However numpy is a little broken : +

-==== mpi4py ==== +
- +
-Is already installed, all that is needed is to load the openmpi module; add the following line to //.bashrc// +
-  module add openmpi-1.6.1-intel +
- +
-==== User Package installation with Anaconda === +
-Modules for anaconda version 2 and 3 are installed on lengau.To load these modules, use the following command (either from the command-line in an interactive session, or in a script: +
-    module add chpc/python/anaconda/2 +
-or: +
-    module add chpc/python/anaconda/3 +
- +
-Using virtualenv with anaconda is not recommended. +
-However, Anaconda does include a similar functionality, which allows users to create an anaconda virtual environment. +
- +
-The following instructions to set up your virtual environment. **YOU NEED ONLY DO THEM ONCE. Please replace USERNAME with your actual username wherever it occurs below.** +
- +
-1. log into lengau +
- +
-2. ''ssh chpclic1'' +
- +
-3. ''module load chpc/python/anaconda/3'' +
- +
-4. ''conda init bash'' +
- +
-5. ''conda create --prefix /home/USERNAME/myenv python=3.6 anaconda'' +
- +
-6. ''conda activate /home/USERNAME/myenv'' +
-_You don't have to use "myenv", just replace it consistently with whatever name you prefer for your virtual environment. "myenv" will work, though._ +
- +
-7. You can now install whatever packages you need, that are not installed already for instance, for rpy2, type: +
-    +
-   conda install rpy2 +
- +
-8. you can now type: +
-  conda deactivate /home/USERNAME/myenv +
-to exit the virtual environment. +
- +
- +
-Now, once you've done this, you MUST DO THE FOLLOWING IN YOUR JOB-SUBMIT SCRIPT: +
-Put it all near the top of your script, but after the #PBS directives: +
- +
-  module add chpc/python/anaconda/3 +
- +
-  conda activate /home/USERNAME/myenv +
- +
-and at the end: +
-  conda deactivate /home/USERNAME/myenv +
- +
-Then submit your script as normal with qsub. +
- +
- +
-if you ever need to install new python packages, just repeat steps 1, 2, 3, 6, 7 and 8 from above. (omit 4 and 5). +
