First of all, thanks for your repo! I am having problems importing the library, I tried to fix it but didn't fix it yet. Can you help me :( image

I am also facing the similar issue. Is there a solution for this apart from downgrading.

I tried to downgrade to !pip install tensorflow==2.2.0 !pip install keras==2.3.1 But later in my code keras is conflicting with tensorflow.

` import tensorflow as tf

import tensorflow.keras as keras

print(tf.version)

print(keras.version) ` Output: 2.4.1 2.4.0

!pip install -U segmentation-models==0.2.1

import segmentation_models as sm

Gives the following error: ModuleNotFoundError: No module named 'keras.legacy'

It seems like TensorFlow 2 is not yet supported.

sumanttyagi commented 3 years ago

when i am running this line :from segmentation_models import Unet getting this error : AttributeError: module 'tensorflow_core.compat.v2' has no attribute 'internal'

can anybody help me with it i am using following env. !pip install segmentation-models !pip install tensorflow==2.1.0 !pip install keras==2.3.1

It seems like TensorFlow 2 is not yet supported.

can you please mention the dependency or requirement to run this repo... i have tried every combination though still not able to fix it...............

I'm currently using this repository with the following requirements: %tensorflow_version 1.x and downgrading the h5py as follows !pip install 'h5py==2.10.0' and then imported the repo as: !pip install -U segmentation-models obviously not tensorflow version 1.x isnt as convincing as 2.x ,but this isworking for me at the moment

mrtushartiwari commented 3 years ago

The following has worked for me on google colab as of now.

!pip3 install tensorflow==2.2
!pip3 install keras==2.3.1
!pip3 install -U segmentation-models

%env SM_FRAMEWORK=tf.keras
import segmentation_models as sm
tf.keras.backend.set_image_data_format('channels_last')
