Numpy error

[BiavaNadia]

Hi, I have just downloaded the ddf-pipeline from the master branch and built the singularity, but I got this numpy incompatibility error at the starting of the pipeline.

pipeline.py ~/software/ddf-pipeline/examples/tier1-jul2018-NVSS.cfg 
RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd . Check the section C-API incompatibility at the Troubleshooting ImportError section at https://numpy.org/devdocs/user/troubleshooting-importerror.html#c-api-incompatibility for indications on how to solve this problem .

This must mean that a dependency has started to pull in a new version of numpy. Let me look at this.

The singularity image will be upgraded to use a more up-to-date numpy (thus being easier to maintain) and newer public versions of DDF.py and kMS.py . Just need to get some of the bugs out of this setup before it can be released.
