I am trying to learn tensorflow and use a book to gain some first insights. The code I am currently trying to get to run can also be found here:
I am using Windows 10, python 3.9.7 and tensorflow 2.6.0. I installed all the packages used here with conda and already tried reinstalling tensorflow which did not solve the problem.
Here is the code up to the line that gives me my error.
import tensorflow as tf
import numpy as np
import matplotlib.pyplot as plt
# Define constants(hyperparameters) used by the algorithm
learning_rate = 0.01
training_epochs = 100
# Set up data to run the regression
x_train = np.linspace(-1, 1, 101)
y_train = 2 * x_train + np.random.randn(*x_train.shape) * 0.33
# Set up input and output variables
X = tf.constant(x_train, dtype=tf.float32)
Y = tf.constant(y_train, dtype=tf.float32)
w = tf.Variable(0.0, name="weights", dtype=tf.float32)
# Define the cost function
cost = lambda : tf.square(Y - tf.multiply(X, w))
# Define operaton for each iteration of the learning algorithm
train_op = tf.keras.optimizers.SGD(learning_rate)
In the last line I get the following error
ModuleNotFoundError: No module named 'keras'
I tried installing keras v2.6.0 in addition to the other packages. However, that did not help and as far as I understand tensorflow comes with keras in it's newer versions. So I removed it again.
I assume something has to be wrong with my tensorflow installation but I am confused since I am able to use other parts of the package without problem. I installed tensorflow following the instructions found here:
https://anaconda.org/conda-forge/tensorflow.
I have already looked at a similar thread. However, the links provided in one of the comments were of no help to me:
ModuleNotFoundError: No module named 'keras' when using tensorflow 2.6
Update:
Here is the list of all packages installed in the environment (I used ´conda list´). Currently keras does not show up as a separate package, since I removed it again:
