[image] Hello, I have a problem in exercise " Improve MNIST with convolutions". Could you help me please? @balaji.ambresh

Have a look on this method of tensorflow: tf.keras.Model | TensorFlow v2.12.0 A model grouping layers into an object with training/inference features. this will help you building your model.

Thank you for creating a public topic. Please specify the input_shape parameter for the 1st layer of the model to get the parameter count. The reason behind locking a few jupyter notebook cells is to ensure that you don’t modify cells that aren’t under your control in the grader environment. If yo…

Hello Balaji, Thanks for your advice. The previous problem was solved. However, even though the results of my code are displayed correctly, the scores shows unexpected error. It may be because my submission time was timed out, as I was stuck on the previous problem for too long. Is there anything I…

Please click my name and message your notebook as an attachment.

[image] [snippet removed by mentor] Hello community, I have a slightly different problem in the same assignment on Enhancing MNIST Dataset with Convolutions, Course 1 Week 3. I failed to launch my model to go through all 10 epochs with 99.5% accuracy because of the callback function instance (2nd…

Please provide the shapes of training_images and training_labels

[image] Thanks you for answering, I went back to the cell when I reshaped and normalized training_images and rewrote them as advised in the official NumPy portal, but a new problem popped up. I do not grasp why the grader brings up some invisible variables like set_model, which I indeed did not de…

Please see here keeping the class to subclass in mind.

Turns out that if you change an uneditable cell with custom content as a new cell, grader doesn’t like it.

Please refresh your workspace and code at places only where indicated in the notebook.
