A small python library to run iterators in a separate process

hojo

A small python library to run iterators in a separate process. This uses the dill package for serialization of the closure and iterator values.

Building

In order to compile the wheel, you need to have maturin installed, and then run make build.

Example

Below is an example where a simple iterator gets wrapped so as to run in a separate process.

def f():
    for i in range(40):
        yield i * i

iter = hojo.run_in_worker(f)
for elem in iter:
  print(elem)

Note that if f uses some python packages, they might not be imported properly. If this happens you may want to have an import declaration at the beggining of f, e.g.:

def f():
    import numpy as np
    for i in range(40):
        i = np.array([i, i+1])
        yield i * i
