AttributeError：模块'keras.utils'没有使用segmentation_models的属性'get_file'

Question

I'm trying to use segmentation models but I can't fix this error. I've searched for this particular one but couldn't find an answer. I'm using pycharm and this error is linked to this specific line of code BACKBONE = 're.net34'

model1 = sm.Unet(BACKBONE, weights=None,
                 encoder_weights='imagenet',
                 classes=num_classes,
                 activation='softmax',
                 decoder_block_type = 'upsampling') 

which is also the 83rd. I searched in the documentation and apparently the versions of tensorflow keras etc satisfy the requirements.I really don't know what to do given the fact that I really tried to install and uninstall everything in many combinations in order to get this piece of code to work.Thank you all for your help and time, Below there's the complete error, hoping it might help you!

Answer 1

You can try:

import segmentation_models as sm

sm.set_framework('tf.keras')

sm.framework()

Worked for me on google colab!

Answer 2

This solves the problem on my laptop.

Answer 3

The other answer provided here didn't work for me. Instead, upgrading keras did the trick for me via:

pip install --upgrade keras

Answer 4

To solve this issue, try importing the module EfficientNetB0 directly, as the code below:

import efficientnet.tfkeras as efn

Answer 5

I had same problem but with vgg u.net model, This worked for me

!apt-get install -y libsm6 libxext6 libxrender-dev

!pip install opencv-python

!pip install git+https://github.com/divamgupta/image-segmentation-keras

from keras_segmentation.models.unet import vgg_unet
