I have a question regarding running my Colab of the w1 assignment.
Hi @Mengyuan_Wang1.
Are you using GPU?
Good catch! Thank you! I didn’t to switch it to GPU as the step in the instruction.
It’s okay
Happy Learning!
If I use GPU how much exactly time to finish the train? I’m trying to use it but still needed approximately 10 hours to finish.
Hey @anggerzhr,
Are you working on same assignment or you ask in general?
yeah on same assignment, even though I already use GPU but it still takes a long time
Can you send me your notebook via DM to check it?
is the issue resolved?
Hello anggerzhr,
Create a mobilenet version 2 model object (THIS CODE NEEDS TO BE WRITTEN LIKE THIS 
mobilenet_model = tf.keras.applications.mobilenet_v2.MobileNetV2
def define_and_compile_model():
define the input layer
inputs = tf.keras.Input (THIS CODE IS INCORRECT, IT SHOULD BE tf.keras.layers.Input
Get the steps per epoch (may be a few lines of code)
ADD THE BELOW CODE LINE TO THE STEPS_PER_EPOCH FOR THE LENGTH OF TRAINING DATA
if length_of_validation_dataset % BATCH_SIZE > 0:
steps_per_epoch += 1
Regards
DP
how do you solve it? My training takes approximately 10 hours
Hi DP
I’m having the same issues as the other students. The model takes a long time to train. I followed all instructions in this thread but it doesn’t seem to solve it.
Can you please advise?

This assignment needs to have look at 2 things your batch size and steps per epoch. So make sure your batch size not too large and steps per epoch is defined for both training and validation dataset as per batch size
I used the same batch size as in the ungraded labs and the steps are computed
How can I solve this problem? To use GDP I have to pay because colab has power limits
Can you send the codes only where the epoch numbers are mentioned via personal DM. Send a screenshot. Click on my name and then message
It is GPU, I didn’t get this power limit, can you explain. If your system doesn’t permit then you will have change your system/laptop/computer, if that is what you meant.
You cannot currently connect to a GPU due to usage limits in Colab. Learn more
To get more access to GPUs, consider purchasing Colab compute units with Pay As You Go
That’s the message I receive.
True, GPU usage limit is a 24-hour cycle. So that’s why if you have used, start the next day in case you do not want to purchase premium colab.
you are not suppose share on posts. kindly delete the image containing codes
