How to execute only 1 of multiple independent inputs/outputs in one model in TensorflowJS


I have a model that has multiple independent inputs/outputs. I want to execute just 1 of them and read the corresponding output. But TensorflowJS complains that I have to fill all of the inputs:

Uncaught Error: Cannot compute the outputs [output_classification1/output_node, output_classification2/output_node, output_classification3/output_node]. 
Missing the following inputs: [input_classification2/input_node, input_classification3/input_node]

Is it not possible to have multiple independent inputs in the model and execute with only 1 filled to get the corresponding output?

Note: The inputs/outputs are independent.
