OK so I removed the system numpy and reinstalled it but then I got:
CcpNmrAnalysis: symbol lookup error: ccpnmr3.1.0/miniconda/plugins/platforms/…/…/lib/libQt5XcbQpa.so.5: undefined symbol: _ZN22QWindowSystemInterface24setPlatformFiltersEventsEb, version Qt_5_PRIVATE_API
I’m not sure this is an improvement!
