I don’t understand the error message
this is my code
and this is the message error
attached my assignment
[code removed - moderator]
Hey friend, if you dont mind, can you share a public Colab for a copy of your assignment, so that I can help? Or just upload it here as an attachment. 
For the happy or sad model, Check the shape of images. Seems to be 150150 not 300300 as described in your first Convolution layer.
As said by @Alassane_Sakande the error you are getting is due to the mismatch of the shapes
The first layer of CNN doesn’t have the same shape as the input
################### C1W4 Here I preprocess the data about happy/sad:
from tensorflow.keras.preprocessing.image import ImageDataGenerator
import zipfile
from os import path, getcwd, chdir
!wget --no-check-certificate \ “https://storage.googleapis.com/laurencemoroney-blog.appspot.com/happy-or-sad.zip”
-O “/tmp/happy-or-sad.zip”
zip_ref = zipfile.ZipFile(“/tmp/happy-or-sad.zip”, ‘r’)
zip_ref.extractall(“/tmp/h-or-s”)
zip_ref.close()
GRADED FUNCTION: image_generator
def image_generator():
START CODE HERE
train_datagen = ImageDataGenerator(rescale=1/255)
train_generator = train_datagen.flow_from_directory(
'/tmp/h-or-s',
target_size=(150, 150),
batch_size=10,
class_mode='binary')
### END CODE HERE
return train_generator

########And everything else works good. Trying to submit i get 0, both part of evaluation say
!!!There was a problem compiling the code from your notebook. Details:
[Errno 2] No such file or directory: ‘/tmp/happy-or-sad.zip’ !!!
Help me, please, Mr.Mentor !
!wget --no-check-certificate https://storage.googleapis.com/laurencemoroney-blog.appspot.com/happy-or-sad.zip -O /tmp/happy-or-sad.zip
you should download the zip via 
approach. There is " issue in your code.
Thank you for the kind response. For my regrets – with “ or without I still have ZERO - [Errno 2] No such file or directory: ‘/tmp/happy-or-sad.zip’
Your idea about “ is very interesting. Here is the question:
Data generator want data from /data, yes?? If so, how to realize it using old lines
zip_ref = zipfile.ZipFile("???/tmp/happy-or-sad.zip", ‘r’)
zip_ref.extractall("/tmp/h-or-s")
zip_ref.close()
to make it like
zip_ref = zipfile.ZipFile("/content/drive/My Drive/ML/tmp/happy-or-sad.zip"
