Calling a remote function with a keyword argument fails

[salsasepp]

Not sure if this is a bug or a missing feature:

import ray

@ray.remote
def f(a):
    return a+1
    
ray.init()

f.remote(1)
f.remote(a=1)

The last line produces this error message when using ray 0.2.0:

Exception: The name 'a' is not a valid keyword argument for the function 'f'

Good catch, and thanks for pointing this out! We probably want to modify this so that remote functions can be called in exactly the same way as regular functions.

The exception is being raised in this line

ray/python/ray/signature.py

Line 149 in 5c70faf

raise Exception("The name '{}' is not a valid keyword argument "

And the logic is generally in the file https://github.com/ray-project/ray/blob/master/python/ray/signature.py.

Hope to see this feature released soon!

@robertnishihara I can take a shot at this, if nobody is working on it?

[robertnishihara]

@abishekk92 sounds great, I don't think anyone is working on it at the moment.

@robertnishihara can you review PR #2081 addressing this issue?
