title: Can't get Tensorflow 2.9 on Mac?
body: <p>I'm trying to build a custom environment for a TF agent but for any modules that I need I get the error:
  <code>ImportError: This version of TensorFlow Probability requires TensorFlow version &gt;= 2.9; Detected an installation of version 2.6.3. Please upgrade TensorFlow to proceed.</code></p>
  <p>For <code>!pip install tensorflow --upgrade</code>I get:
  <code>Requirement already satisfied: tensorflow in ./opt/anaconda3/lib/python3.9/site-packages (2.6.5)</code></p>
  <p>I also tried <code>!pip install tensorflow-macos</code> because it was suggested on pypi.org but then I get:</p>
  <p><code>ERROR: Could not find a version that satisfies the requirement tensorflow-macos (from versions: none) ERROR: No matching distribution found for tensorflow-macos</code></p>
  <p>If I try to specify 2.9 with <code>!pip install 'tensorflow==2.9' --upgrade</code> that does not work either:</p>
  <pre><code>ERROR: Could not find a version that satisfies the requirement tensorflow==2.9 (from versions: 2.5.0, 2.5.1, 2.5.3, 2.6.0rc0, 2.6.0rc1, 2.6.0rc2, 2.6.0, 2.6.2, 2.6.3, 2.6.4, 2.6.5, 2.7.0rc0, 2.7.0rc1, 2.7.0, 2.7.1, 2.7.2, 2.7.3) 
  ERROR: No matching distribution found for tensorflow==2.9
  </code></pre>
  <p>I also tried all of these in my Mac terminal (with <code>python -m pip...</code>) as well as in VS code terminal but I really can't seem to get the Tensorflow version that I need for the agents and environments …</p>
