Error generating normalized bigwig files

[sjhosui]

I'm trying to get haystack up and running but get an out of range error generating the bigwig files. This is the output after running haystack_run_test.

I get a similar error when running on real data.

Thanks, Shannan

The problem is probably due to the lastest numpy or pandas update. I would use the docker container or create an environment that forces these packages to have earlier versions that were released in 2017
