Trying the test_sobo_thc function from experiments/visualize_ThreeHumpCamel.py I got this error:

The problem seems to be that the dtype of a variable was object and numpy didn't like that.
For fixing this issue would have been enough to fix it here:
Trying the
test_sobo_thc
function fromexperiments/visualize_ThreeHumpCamel.py
I got this error:The problem seems to be that the

of a variable wasobject
and numpy didn't like that. For fixing this issue would have been enough to fix it here:https://github.com/sustainable-processes/summit/blob/c3deffc90aad5573c32de2968ba26d95e3ccaf5a/summit/strategies/sobo.py#L316
But for staying safe, I corrected it in the previous definition of the
input
variable.
