Python on Midway

This material can be found in the Intro to RCC Workshop

Create a Conda Environment¶

First ssh into midway2

$ ssh <your_id>@midway2.rcc.uchicago.edu

You’ll want to load a Python module

$ module avail python

should yield

---------------------------- /software/modulefiles2 ----------------------------
python/anaconda-2019.03          python/cpython-3.8.5             
python/anaconda-2020.02(default) python/intel-2020.up1            
python/cpython-3.7.0             
------------------------------- /etc/modulefiles -------------------------------

You can load the default python module (python/anaconda-2020.02) using:

$ module load python

Once you have loaded the module, you can create a conda environment for whatever project you’re working on

$ conda create –name=<my-env> python==<python-vers>
$ conda activate <my-env>

WARNING: nothing computationally intensive should be run from a login node

$ module load python
$ # export the login node IP address
$ export IP_ADDR=`ifconfig eno1 | grep 'inet ' |  awk '{print $2}'`
$ # choose a port number
$ export PORT_NUM=$(shuf -i8000-9000 -n1)
$ # launch jupyter
$ jupyter notebook --no-browser --ip=${IP_ADDR} --port $PORT_NUM

You can then open the link that the command creates
