Description

An error occurs if a user function definition overrides a built-in function for converting different PyDML syntax. For example:

X = random.normal(4, 3, 1)
print(sum(X))

def rand(x: int) -> (y: int):
y = x*2

org.apache.sysml.parser.LanguageException: Unsupported Parameters : ERROR: line 2, column 6 – Expecting matrix parameter for function SUM
