title: AttributeError: module 'lora' has no attribute 'lora_receiver'
body: <p>I want to get the message from a Lora communication (which is in a .iq file), by using GNU-Radio but when i try to use one of the &quot;Lora&quot; block i have an error &quot;AttributeError: module 'lora' has no attribute 'lora_receiver'&quot;.</p>
  <p>I run GNU-Radio 3.8.1.0 in a VM (DragonOS_focal_R22.1) where gr-lora is already installed.</p>
  <p>Here is some screen of my blocks and the error :</p>
