@freeman-lab I have just tried installing thunder on one of our machines which is running ubuntu.
I have launched a cluster on amazon EC2 and then I have tried to view the first image of the data set by calling image(images[0]) but this error is being returned:
Py4JJavaError: An error occurred while calling z:org.apache.spark.api.python.PythonRDD.runJob.

@tomsains @shariqiqbal2810 that issue should be properly fixed now, turns out to have been a problem with the git tag, so no upgrade / reinstallation neccessary
if you pip install, say, v0.5.1, you should get v0.5.1 on the cluster, and there shouldn’t be any dependency conflicts

also @/all you may have noticed a reorgnization to the repo by which the top-level scala folder has been removed and what was the python folder is now top-level
this shouldn't have any user-facing consequences, but especially if you’ve been working against the master branch, be aware that things have moved around
the big win is that we eliminated all scala dependencies, which should prevent some deployment / installation errors, and is part of a road map torwards simplifying deployment more genreally
