Problem: AttributeError: 'tuple' object has no attribute 'layer'

[FioPio]

Whenever I try to train, test or whatever I get allways the same error, I have the code setup as you explain, but I keep getting the same error:

I have installed all the versions you specify with the requirements, and I am able to run the data_process_v2 script without any problem.
Do you know what is happening?

Thank you in advance,

Hi, did you solve it? I has the same problem as you

[FioPio]

No, I haven't solved it, I more or less know the issue, but I did not test it yet

[yeluo80808]

can you tell me why

[changliu19]

Hi Ferriol and yeluo,

We do not have this error in our environment - but such kind of error (no attribute 'layer') usually indicates the incompatibility between keras and tf.keras. Our code use the standalone keras package, so please make sure all of your codes and their dependencies also use keras only.

Hi @ntuLC,

I have the same problem. Can you release your Dockerfile in a github link?

[Galaxfyos]

Hi @ntuLC,

I have the same problem. Can you release your Dockerfile in a github link?

I have the same problem，have you solved it?

[zghehejun233]

I have the same problem, and I'm wondering how this function called tensorflow_lite. Have you solved it? I urgently need some of these data now.

[freshpearYoon]

I also have same problem. Is there anyone who solved it? I've done pip install -r requirement.txt , and done data preprocessing as suggested on readme.md

[freshpearYoon]

i fixed this error by installing tensorflow 2.11 and changing from keras import Layer to tensorflow.keras!
