title: ModuleNotFoundError: No module named 'keras' using tensorflow 2.6.0 in Anaconda
body: <p>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:</p>
  <p><em><a href="https://github.com/chrismattmann/MLwithTensorFlow2ed/blob/tensorflow2/TFv2/ch03/Listing%203.1-3.2.ipynb" rel="nofollow noreferrer">https://github.com/chrismattmann/MLwithTensorFlow2ed/blob/tensorflow2/TFv2/ch03/Listing%203.1-3.2.ipynb</a></em></p>
  <p>I am using <code>Windows 10</code>, <code>python 3.9.7</code> and <code>tensorflow 2.6.0</code>. I installed all the packages used here with conda and already tried reinstalling tensorflow which did not solve the problem.</p>
  <p>Here is the code up to the line that gives me my error.</p>
  <pre><code>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=&quot;weights&quot;, 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)
  </code></pre>
  <p>In the last line I get the following error</p>
  <pre><code>ModuleNotFoundError: No module named 'keras'
  </code></pre>
  <p>I tried installing <code>keras v2.6.0</code> 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.</p>
  <p>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:</p>
  <p><em><a href="https://anaconda.org/conda-forge/tensorflow" rel="nofollow noreferrer">https://anaconda.org/conda-forge/tensorflow</a></em>.</p>
  <p>I have already looked at a similar thread. However, the links provided in one of the comments were of no help to me:</p>
  <p><em><a href="https://stackoverflow.com/questions/69733719/modulenotfounderror-no-module-named-keras-when-using-tensorflow-2-6">ModuleNotFoundError: No module named &#39;keras&#39; when using tensorflow 2.6</a></em></p>
  <p><strong>Update:</strong></p>
  <p>Here is the list of all packages installed in the environment (I used ´conda list´). Currently <code>keras</code> does not show up as a separate package, since I removed it again:</p>
