module 'tensorflow._api.v1.compat.v2' has no attribute '__internal__' google colab error

Question:

I am running a tensorflow model on google colab. Today, I got this error:

 Using TensorFlow backend.
    Traceback (most recent call last):

Previously, things had been running smoothly, so I’m not sure why this happened.
I am using Python 3.7.10, and these are the packages I am supposed to use:

absl-py==0.9.0
astor==0.8.1
gast==0.2.2
google-pasta==0.1.8
grpcio==1.26.0
h5py==2.10.0
Keras==2.3.1
Keras-Applications==1.0.8
Keras-Preprocessing==1.1.0
Markdown==3.1.1
numpy==1.18.1
opencv-contrib-python==4.1.2.30
opt-einsum==3.1.0
protobuf==3.11.2
PyYAML==5.3
scipy==1.4.1
six==1.14.0
tensorboard==1.15.0
tensorflow==1.15.0
tensorflow-estimator==1.15.1
termcolor==1.1.0
tqdm==4.41.1
Werkzeug==0.16.0
wrapt==1.11.2

Perhaps colab recently upgraded some libraries? I am sure that I followed the same installation steps as I usually do.

EDIT:
I think there may be an issue in the keras version.
Here are the first few lines of the file I am running:

from keras.layers import Conv2D, Input, BatchNormalization, LeakyReLU, ZeroPadding2D, UpSampling2D, Lambda
from keras.layers.merge import add, concatenate
from keras.models import Model
from keras.engine.topology import Layer
import tensorflow as tf

If I remove all of the lines starting with "from keras", I don’t get the error. However, I never touched these lines before, so I don’t know why they would suddenly cause an error now. Also, it is not the python version causing this error, because colab changed it to 3.7.10 in April and I had no problem.

Answers:

Try downgrading Python to 3.6 using this link. You need to re-install the packages you previously used.

One morning I woke up and my code was giving the exact same error (in google colab).

I was running this code to downgrade my tensorflow

!pip install tensorflow==1.13.0

I replaced it with:

%tensorflow_version 1.x

Everything else remains the same. It worked!

try this one :

!pip uninstall keras-nightly

!pip install h5py==2.10.0

Answered By: nada belhadjslimen

Try these parameters, it works with me

!pip3 uninstall keras-nightly
!pip3 uninstall -y tensorflow
!pip3 install keras==2.1.6
!pip3 install tensorflow==1.15.0
!pip3 install h5py==2.10.0

I had the same problem but using python 3.7 together with

tensorflow==1.15.0
keras==2.1.6

Worked for me.
