Error: TypeError: ufunc 'isfinite' not supported for the input types

I am getting error when running test files,

python -m nkululeko.explore --config tests/exp_agedb_explore_data.ini

Output:

I run it again but the error was gone, I don't no why. Maybe updating numpy.

@felixbur I reopened this issue since I can reproduce this issue. This issue gone when I run for second time.

Steps to reproduce:

1. Remove all results inside test.

    rm -fr tests/results
   

2. Run it once, it will fail.

    python -m nkululeko.explore --config tests/exp_agedb_explore_data.ini
   

3. Run for the second time, it will success and done.

    python -m nkululeko.explore --config tests/exp_agedb_explore_data.ini

thanks, I'll check it out
