Whenever I try to use @jit on my class method, I get IndentationError: unexpected indent

Question

I\'ve been trying for several days to get @jit working to speed up my code. Finally I came across this, describing adding @jit to object methods: h

Answer 1

From what I can see from the documentation, you cannot apply the decorator to a method; the error you see is from the JIT parser not handling the source code indentation when not in the context of a class statement.

If you want the body of that method to be compiled, you'll need to factor it out to a separate function, and call that function from the method:

@jit(void(object_, float_[:,:], int_[:], int_)) 
def train_function(instance, X, y, H):
    # do stuff

class GentleBoostC(object):
    def train(self, X, y, H):
        train_function(self, X, y, H)
