Why scipy.integrate shows has no "simpson" attribute?
Question:
I have some python code which uses function scipy.integrate.simpson
So for example I import scipy using import scipy.integrate as scp_int and then use it in following way:
vol_r = scp_int.simpson(f_integrand_r,dx=_dx1,axis=0)
I get this error
vol_r = scp_int.simpson(f_integrand_r,dx=_dx1,axis=0)
AttributeError: module 'scipy.integrate' has no attribute 'simpson'`
I have made sure that I have scipy package installed, using pip install scipy, and I have restarted computer. I don’t know why is this happening? Can someone give the reason or help me solve this issue?
Answers:
I suspect you are using version 1.5 (or an older version) of SciPy.
If you don’t know which version you have installed, you can check with
import scipy
print(scipy.__version__)
simpson was added in 1.6.0; it is the new name for the old function called simps. If you can’t upgrade, you should be able to use simps instead of simpson.
