  <pre><code>python -c 'from caffe2.python import core' 2&gt;/dev/null &amp;&amp; echo "Success" || echo "Failure"
  </code></pre>
  
  <p>it echo failure.
  further when I run next command </p>
  
  <pre><code>python -m caffe2.python.operator_test.relu_op_test
  </code></pre>
  
  <p>It gives output as -
  <code>Error while finding module specification for 'caffe2.python.operator_test.relu_op_test' (ModuleNotFoundError: No module named 'caffe2.python')</code></p>
  
  <p>While I have successfully run the other commands, Can anyone please point out the mistake/s I am committing.
