<p dir="ltr">So Dylan,</p>
<p dir="ltr">It seems you are trying to bypass installation. I suggest avoiding shortcuts. </p>
<p dir="ltr">Using code in centralized storage also implies you need to make sure code is accessible. </p>
<p dir="ltr">If you install whatever you need on each node upon startup you should be good unless I am missing somethings. </p>
<p dir="ltr">In any case, getting back to basics and simplifying things may help. </p>
<p dir="ltr">Good luck. </p>

Since IPython is installed on the EBS volume, it should be accessible by all nodes. The only issue is that the EBS volume needs to be on the python path at the time the plugin execute. I have gotten around this by having a .bashrc file with the lines:</div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small"><br></div><div class="gmail_default"><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small">export PATH="path_to_EBS_volume/bin/<wbr>miniconda2/bin:$PATH"</div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small">source activate python2</div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small">that gets copied to the root directory upon startup. However, this .bashrc file is not getting sourced prior to running the ipcluster plugin.

<p dir="ltr">Did you install Ipython on all nodes? </p>
<p dir="ltr">It is the first thing that comes to mind. </p>
<p dir="ltr">There are plugins that come with starcluster to install other software through pip. Did you use one of there?</p>
<p dir="ltr">The third thing at comes to mind is using the Ipython plugin: </p>
