Issues when trying to prove a simple onnx file

[HadiEsna]

I've made a simple onnx and input file following the examples on the repo.
Then when I tried to make a proof of the execution I ran into this error

[*] [0s, ezkl] - command:

[E] [0s, ezkl] - failed: Failed analyse for node #3 "Cast" onnx.Cast
Error: Failed analyse for node #3 "Cast" onnx.Cast

Caused by:
    0: Infering facts
    1: Applying rule inputs[0].shape == outputs[0].shape
    2: Unifying shapes 7 and 1
    3: Impossible to unify Val(7) with Val(1).

I went through the code to figure out what is the problem but I had no luck there.
Please let me know if I need to provide the actual input and onnx file to find what is the cause of the problem.

Heya ! Can you send me the onnx file :)

Issue was that the file was a tree based model as highlighted in #99.
