# Open edX APIs often require an access token that is obtained through the OAuth2 protocol. Here are the general steps you would take:
# Request an access token: The first step is to request an access token. For this, you would send a POST request to the /oauth2/access_token endpoint with your client ID and secret. Here’s an example of how to do it with requests in Python:
import requests
import json

url = "https://your-open-edx-instance.com/oauth2/access_token"

headers = {
    "Content-Type": "application/json"
}

  X = np.concatenate([np.ones((X.shape[0], 1)), X], axis=1)

  # Compute the transpose of X

  # Compute the dot product of X_t and X
