My function returns the correct result for Y, but I am also getting the following error.
AssertionError: Use the TensorFlow API
Can anyone help?
Hi, @fabian.
You’re probably not using tf.constant to initialize X, W and b. Look at the example provided for X.
Thank you for your response.
I am using tf.constant(np.ra…) t initialize X,W and b
and tf.Variable(np.ra…) for Y.
I’m also getting the correct output vector for Y, but I also get this weird error message (and 0 on the grade).
Just assign the tensor that results from computing W X + b to Y. There is no need to create a randomly initialized TensorFlow variable for it 
P.S. The error message is indeed misleading. The notebook raises that exception because it is expecting a tensor and you’re probably returning a variable.

Yes - that works.
Thank you!
Glad to help! Good luck with the rest of the assignment
