 +=== Run Anaconda Navigator on Your Laptop ===
 +
 +You will need to be on the campus wireless network for this procedure to work. General internet access is not available. The following procedure is run from the command line.
 +
 +1. Log into your account using on the cluster using [[http://mobaxterm.mobatek.net|MobaXterm]] (see above) 
 +
 +  $ ssh dsl.saintpeters.edu
 +
 +2. Once logged in, run the following:
 +
 +  $ jupyter-notebook --generate-config
 +
 +3. Edit the config file (use ''vi'' or ''nano''):
 +
 +  $ nano .jupyter/jupyter_notebook_config.py
 +
 +4. Change this line:
 +
 +   #c.NotebookApp.ip = 'localhost'
 +
 +5. To the following (note remove "#") save and exit:
 +
 +   c.NotebookApp.ip = '127.0.0.1'
 +
 +6. Now run from MobaXterm command line:
 +
 +  $ anaconda-navigator

 ==== Use TensorFlow ==== ==== Use TensorFlow ====
  
-TBC+Tensorflow is available as part of Anaconda Python. The easiest (and recommended) way to use Tensorflow with Python through the high level [[https://keras.io/guides/|Keras]] library.  
 + 
 +It is also possible to use [[https://pythonprogramming.net/tensorflow-introduction-machine-learning-tutorial/|low level Tensorflow]] directly. 
 + 
 +**Note:** Python Keras and Tensorflow can be used on any workstation, Only three workstations have GPUs (limulus7-tf, limulus8-tf, limulus9-tf), however both Keras and Tensorflow will run without using a GPU (applications will run slower). 
 + 
 +**Testing:** You can test tensorflow using the following: (on limulus7-tf, limulus8-tf, limulus9-tf) 
 + 
 +<code> 
 +$ use_conda 
 +$ python   /opt/cluster/public/apps/testing/test-cuda.py  
 + 
 +Num CPUs Available:  1 
 +Num GPUs Available:  1 
 +</code> 
 + 
 +GPUs will be present on limulus7-tf, limulus8-tf, limulus9-tf, all otheer nodes will show just one CPU. 
 + 
 +**GPU Monitoring:** You can use ''nvidia-smi'' to monitor the GPU. You must be logged into the GPU system.
