Variables output from pythonCommand node to other nodes

[rupert thorpe]

Hello,

I have been experimenting with ML stuff with gaffer, motivated by the new gafferML nodes.

(The example works well for me on windows) 

I am thinking that allot can be done just using gaffer to automate things using the standard gaffer nodes. I linked up a large language model to a box via a python expression:

However these things can be very slow to run, and it makes sense to me for them to be task nodes instead to more easily control the execution.

I tried to make the same setup with a pythoncommand node, but it is not clear to me how to pass the output variable back to other nodes in gaffer.

I could write the output to a file - and this would probably be required if I was submitting to a farm, but if everything will run locally I should be able to pass the variables more directly I think.

I guess this is possible but I couldn't get anything to work.

I couldn't work out how to do it though - perhaps it is trivially easy  

I think this will be a situation with allot of ML stuff in gaffer, especially when running on older hardware.
