week 3 when i submit
it show
nbgrader encountered a fatal error while trying to validate ‘submitted/courseraLearner/W3A1/Tensorflow_introduction.ipynb’
it has been shown every time
The screen shot or image that you posted is truncated and not legible.
It might also be helpful to see what the actual grader says using “Submit Assignment” rather than clicking the “Validate” button.
One thing you might want to try is “Kernel → Restart and Clear Output” and then click “Cell → Run All”. That will run the whole notebook from a clean memory image. Also note that you may encounter issues if you have added print statements in one of the loops that generates a lot of output when you run the training. That will cause the memory footprint to grow large which causes problems.
You’re missing the point here. In this exercise we are supposed to be using TensorFlow, not numpy, for the operations. They are just showing you the “numpy equivalent” and you have to come up with the way to code the equivalent logic using TF, right?
restart donot help, i have try for week to submit but every time it false
Here is what it says in the instructions for that section:
### Exercise 5 - forward_propagation
Implement the `forward_propagation` function.
**Note** Use only the TF API.
* tf.math.add
* tf.linalg.matmul
* tf.keras.activations.relu
