Adding bounds to curve_fit: Positional arguments error

Trying to perform curve-fitting on a function, using scipy curve_fit:

param_bounds=((-np.inf,-np.inf,0),(np.inf,np.inf,1))
OneCyParams, extras = curve_fit(func,xdata,ydata,bounds=param_bounds)

Resulting error:

    453     if weights is None:
    454         def func_wrapped(params):
--> 455             return func(xdata, *params) - ydata
    456     else:


    457         def func_wrapped(params):

TypeError: OneCycle() takes 2 positional arguments but 4 were given

OneCycle is the function I'm fitting.

This error goes away if I remove the bounds argument. What am I doing wrong?

This error was because the relevant func only has one parameter.

Once the param_bounds was appropriately adjusted, the problem resolved.
