2.This is my code in Jupyter Notebook. I just started with python and get the error I mentioned in the headline. I would be very thankful if someone could help me wizh a code example to solve the problem.

As per my understanding, the contrib got deleted in TF2. So there is a quick solution to replace it with an estimator suggested here in this link

https://github.com/tensorflow/community/blob/master/rfcs/20180907-contrib-sunset.md

in the case of using tf1

tf.contib.layers.batch_norm throws error "AttributeError: module 'tensorflow.compat.v1' has no attribute 'contrib'".

Solution: tf.estimator.layers.batch_norm

contrib is a headache of Google Team. We have to deal with the issue of contrib case by case. I just take two examples as follows.

1.With regard to CNN, it has the following method

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

# -initializer = tf.contrib.layers.xavier_initializer(seed=1)
initializer = tf.truncated_normal_initializer(stddev=0.1)

2.With regard to RNN/LSTM, it has the following different method.

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

# -outputs, states = tf.contrib.rnn.static_rnn(lstm_cells, _X, dtype=tf.float32)
outputs, states = tf.compat.v1.nn.static_rnn(lstm_cells, _X, dtype=tf.float32)

I think you need to add the following line in your python file which you are going to execute it.

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

tf.contrib was removed from TensorFlow once with TensorFlow 2.0 alpha version.

Most likely, you are already using TensorFlow 2.0.

You can find more details here: https://github.com/tensorflow/tensorflow/releases/tag/v2.0.0-alpha0

For using specific versions of tensorflow, use

pip install tensorflow==1.14

or

pip install tensorflow-gpu==1.14
