I was trying to implement smile detection project from kaggle on to my Google collab.

smile-detection | Kaggle[^]

I have downloaded the datasets and uploaded on my drive and mounted it so my problem is:

C++

H=model.fit(train_X,train_y,validation_data=(test_X,test_y),epochs=15,batch_size=32)

It shows this error:

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
<ipython-input-7-094cecbab710> in <cell line:="" 1="">()
----> 1 H=model.fit(train_X,train_y,validation_data=(test_X,test_y),epochs=15,batch_size=28)

   1318         if self._inferred_steps == 0:

   1320 
   1321     def _configure_dataset_and_inferred_steps(

ValueError: Expected input data to be non-empty.

So I tried changing the batch size to 4 16 but same error.

What I have tried:

I tried changing the batch size several times.

"it keeps showing error"
Sorry, no one here can see your screen or read your mind.

updated the link now you can access and see the code

The message is cleaer, you have a data set that is incomplete. So you need to examine what data you are passing in to the code. This is not something anyone here can do for you.

ERROR MESSAGES ARE THE CORE CLUES TO THE PROBLEM! Hover the mouse over your question and click the "Improve question" widget. Edit your post and add the EXACT error messages you're getting.

OK, so what do you think this means: "ValueError: Expected input data to be non-empty.".

It sounds like one of the parameters you're passing into the .fit() call doesn't contain the data you think it does.

i'm confused i have downloaded the datasets uploaded to my drive and mounted it and also set the directory
why it wouldn't find the data is there more to do?

would you please kind enough to tell me where exactly my problem lies and how to fix it

I HAVE NO IDEA WHERE THE PROBLEM IS! YOU have to DEBUG the code and find out what's in the variables you're passing into that function call. ONLY YOU CAN DO THAT!

"It doesn't work" is probably the most useless problem report we get - and we get it a lot. It tells us nothing about what is happening, or when it happens - and "I get error" means just that - "it doesn;t work"!

So tell us what it is doing that you didn't expect, or not doing that you did.
Tell us what you did to get it to happen.
Tell us any error messages.
Use the "Improve question" widget to edit your question and provide better information.

Assuming you get an error message of some sort - but we have no idea what - have a look here: How to Write Code to Solve a Problem, A Beginner's Guide Part 2: Syntax Errors[^]
It primarily deals with syntax errors, but the same logic often applies to run time errors as well if that is what you are getting.
