Pypepad not opening after running "" in Anaconda prompt


I’m new to using VMTK and I’ve unfortunately run into an issue with attempting to open the Pypepad using the Anaconda prompt. Every time I run the “” line (as shown in the tutorials on the VMTK website), a separate prompt opens and immediately closes with the Anaconda prompt displaying my working directory on a new line below, indicating nothing happened. I’ve tried to reinstall VMTK with no luck and am uncertain as to what the issue is. Help would much be appreciated.
