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 .
