title: ModuleNotFoundError: No module named 'dbn'
body: <p>I need to use &quot;Deep belief Network&quot; in python 3.7.10 through spyder in a virtual environment. so I used the following command :</p>
  <p><em><strong>from dbn.tensorflow import SupervisedDBNClassification</strong></em></p>
  <p>when running the program it gives me the message :ModuleNotFoundError: No module named 'dbn' even after installing DBN module using &quot;pip install dbn&quot;or &quot;pip install DBN&quot;
  knowing that I checked the path of the module.</p>
