Float number error in parameter scan

Asked by Rouzbeh

Hello,

I am trying to scan vector dark matter coupling in our simplified model.
I want to choose the range scan:1 range(0.003, 1, 0.001) which is float, and I got this error:

TypeError : 'float' object cannot be interpreted as an integer
Please report this bug on https://bugs.launchpad.net/mg5amcnlo.

So, how can I use float numbers in the range?
Thank you so much for your consideration.

That's a limitation of the range function in python.

But you can use:
scan:1 [i/1000. for i in range(3, 1000, 1)]

Cheers,

Olivier
