ModuleNotFoundError: No module named 'keras.engine'"

[rholgado]

Hi!

I have the following requirements installed:

tensorflow>=2.8.0
keras_applications>=1.0.8
kapre>=0.3.7
I have also installed classification-models-1D using pip.

When I run the following example code in my Jupyter notebook:
from classification_models_1D.tfkeras import Classifiers
ResNet18, preprocess_input = Classifiers.get('resnet18')
model = ResNet18(input_shape=(224*224, 2), weights='imagenet')

I encounter the error:

ModuleNotFoundError: No module named 'keras.engine'

I have tried different versions of TensorFlow and Keras, but the issue persists. Can anyone help me resolve this?

Thank you!

[ZFTurbo]

Can you try exactly:

tensorflow==2.8.0
keras_applications==1.0.8
kapre==0.3.7

[rholgado]

Oh thank you so much! It seems that it worked, but I've encountered a new error: "TypeError: list indices must be integers or slices, not str" It might be related to how indices are accessed internally in the code.

Could you provide some guidance on how to resolve this new error? I appreciate any help you can offer!

Yeah sure! This is what I got:

Hi again. Sorry I'm a little bit desperate and maybe someone can help me.

I've been analyzing the code, and it seems the issue arises when adjusting the input shape to be compatible with BatchNormalization after importing from tensorflow.keras using the following snippet:

from tensorflow.keras import layers, models

Example bn_params dictionary

bn_params = {
'axis': 1,
'momentum': 0.99,
'epsilon': 1e-5,
'center': True,
'scale': True,
}

Example usage in a model

input_tensor = layers.Input(shape=(224*224, 2))
x = layers.BatchNormalization(**bn_params)(input_tensor)

While layers.BatchNormalization(**bn_params) appears correct, the error arises when attempting to adjust the input shape to align with BatchNormalization. I'm unsure how to correct this issue."

[ZFTurbo]

I can't reproduce your issue. I cloned repo, then installed dependencies in fresh venv. After I run tst_1D_classification_tfkeras.py:

Tensorflow version: 2.8.4
Go for resnet18
(100, 441000, 2) (100, 431, 512)
Params: 11 M Memory: 0.416 GB Time: 0.0735 sec
Go for resnet34
...

[rholgado]

Ok, i understand. And what is your version of python, keras and keras aplication? Tensor flow is 2.8.4 ok

[ZFTurbo]

• keras==2.8.0
• keras_application==1.0.8
• python==3.8

[rholgado]

I don't know what is happening. Because i have this:
TensorFlow version: 2.8.0
Keras version: 2.8.0
Keras Applications version: 1.0.8
Kapre version: 0.3.7
Python version: 3.8.10 (default, Jun 16 2021, 14:20:20)
[GCC 9.3.0]

And then I run this:
from classification_models_1D.tfkeras import Classifiers

ResNet18, preprocess_input = Classifiers.get('resnet18')
model = ResNet18(input_shape=(224*224, 2), weights='imagenet')

And i get the same error "TypeError: list indices must be integers or slices, not str"

[ZFTurbo]

Can you add print(bn_params)

before x = layers.BatchNormalization(name='bn_data', **bn_params)(img_input)

[rholgado]

Hi ! I got this "{'axis': 2, 'momentum': 0.99, 'epsilon': 2e-05, 'center': True, 'scale': True}" and then the "TypeError: list indices must be integers or slices, not str"

[ZFTurbo]

Either set weights=None or use include_top=False.
