Python Get

Hi everyone, I'm testing the Python package and I have some issues using "Get".

I created a super simple module (mio_modulo.py) where I declare a variable test.
If I use "Eval" to print the value of test, I can see the correct value printed in the Bonsai shell.
If I try to use "Get", I receive an error: "The module has no attribute 'test'".

Now I'm sure I'm missing something because in the "Get" properties the Module field is grayed out and I can't indicate the module to use.

What am I missing?

Heya!

If you want to use CreateModule you will have to pass it as a property to the Get:

Otherwise, you can also run your script at the CreateRuntime subscription and use the "global" scope:

<?xml version="1.0" encoding="utf-8"?>
<WorkflowBuilder Version="2.9.0"
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                 xmlns:rx="clr-namespace:Bonsai.Reactive;assembly=Bonsai.Core"
                 xmlns="https://bonsai-rx.org/2018/workflow">
  <Workflow>
    <Nodes>
      <Expression xsi:type="Combinator">
        <Combinator xsi:type="py:CreateRuntime">
          <py:PythonHome>.venv</py:PythonHome>
          <py:ScriptPath>mio_modulo.py</py:ScriptPath>
        </Combinator>
      </Expression>
      <Expression xsi:type="Combinator">
        <Combinator xsi:type="py:Eval">
          <py:Expression>print(test)</py:Expression>
        </Combinator>
      </Expression>
      <Expression xsi:type="Combinator">
        <Combinator xsi:type="rx:Timer">
          <rx:DueTime>PT1S</rx:DueTime>
        </Combinator>
      </Expression>
      <Expression xsi:type="Combinator">
        <Combinator xsi:type="py:ObserveOnGIL" />
      </Expression>
      <Expression xsi:type="Combinator">
        <Combinator xsi:type="py:Get">
          <py:VariableName>test</py:VariableName>
        </Combinator>
      </Expression>
    </Nodes>
    <Edges>
      <Edge From="0" To="1" Label="Source1" />
      <Edge From="2" To="3" Label="Source1" />
      <Edge From="3" To="4" Label="Source1" />
    </Edges>
  </Workflow>
</WorkflowBuilder>

Hope it helps!
