I have a SymPy script with a.o.
f_mean = lambdify([mu, sigma], mean, modules='numpy')
where mean is a function of mu and sigma and mu and sigma are both arrays
mu = symbols('mu_0:%d' % n, real=True, bounded=True)
sigma = symbols('sigma_0:%d' % n, positive=True, real=True, bounded=True)
Unde
rror: () missing 1 required positional argument: 'x_1'
Hope this helps to clearify the point.
Cheers, Janwillem

TypeError: () missing 2 required positional arguments: 'a_0' and
'a_1'
and the same for a variation without *
print('function value=', fx(X, a))
TypeError: () missing 2 required positional arguments: 'a_0' and
'a_1'
So still all help
