ModuleNotFoundError: No module named 'Florence.VariationalPrinciple.DisplacementApproachIndices'

It seems like the installation has not been successful. Is this under a virtual environment? I have no issues with 18.04.

[nicolaskr]

It is not a a virtual environment.
The installation on an another machine, with the same steps, on ubuntu 16.04 has worked.

I will retry on the first machine (18.04).

Retried on ubuntu 18.04, with conda environment and without.

The same error appears when runnig " From Florence import * " on python 3 and python 2

This is an installation issue and may have been caused due to ABI incompatibility. DisplacementApproachIndices is an extension module and if it can't be found it means it was not built. Can you instead do:

pip install Florence -v

or

pip install Florence -vvv

and report the build log here?

It's working
I did not have BLAS installed on the ubuntu 18.04 machine

sudo apt-get install libopenblas-dev solved the problem

The error was clear when running python setup.py build:

fatal error: cblas.h: no such file or directory
#include <cblas.h>

This closes #7
