Error occurred when I run the demos.

Hi there,

I use a Mac and I met the following problem when I run the first demo: ./demo.py 20newsgroups. And none of the build a topic demo can run successfully on my Mac. I followed the instruction to clone this repository onto my Mac already.

the error message as follows when I run ./demo.py 20newsgroups:

Can you help me deal with this?

And there is another question: I can start the data server and visualization client at the same time. What the next step I can do? I can only find a upload datasets option in the server page and after I upload the dataset, nothing happened to the client. Can you tell me how to output a figure just like your article ---- termite: : Visualization Techniques for Assessing Textual Topic Models by using the Mallet? I can't find any instruction document on the net. Thank you very much!!

demo.py calls bin/fetch_dataset.sh which tries to curl the datasets from http://homes.cs.washington.edu/~jcchuang/termite-datasets/$DEMO.zip. however, the datasets are no longer there: http://homes.cs.washington.edu/~jcchuang/termite-datasets/

are the datasets available somewhere else?
