QuickStart example script is erroring #204
Description
Describe the bug
The quickstart example script here https://sysidentpy.org/getting-started/quickstart-guide/ errors.
To Reproduce
Steps/code to reproduce:
- Install sysIdentpy per instructions.
- Run the example code at the provided link.
- See error: "ValueError: If order_selection is False, you must define n_terms value."
Expected results
I'd like to see this run as an example I could extend to my own project.
Actual results
The error
File ~\anaconda3\envs\sysidentenv\Lib\site-packages\sysidentpy\parameter_estimation\estimators.py:256, in Estimators.recursive_least_squares(self, psi, y)
254 k = np.divide(k_numerator, k_denominator)
255 self.xi[i, 0] = y[i, 0] - np.dot(psi_tmp.T, theta[:, i - 1])
--> 256 theta[:, i] = list(theta[:, i - 1].reshape(-1, 1) + k.dot(self.xi[i, 0]))
258 p1 = p.dot(psi[i, :].reshape(-1, 1)).dot(psi[i, :].reshape(-1, 1).T).dot(p)
259 p2 = (

ValueError: setting an array element with a sequence. The requested array would exceed the maximum number of dimension of 1.
Environment
sysIdentpy = 0.2.0
Additional context
I've tried adding various n_terms values, getting errors like "ValueError: setting an array element with a sequence. The requested array would exceed the maximum number of dimension of 1."
In response, I've tried changing my input to model to:
model.fit(X=np.squeeze(x_train), y=np.squeeze(y_train))
Which also errors. Please advise
