It is LINQ free btw. The goal to make it hackable on the go.

Usage
=====
import rexpython as rx

def on_subscribe(emitter):
emitter.setDisposable(ActionDisposable(lambda: sys.stdout.write("disposed")))

print ("subscribed")
for i in xrange(1, 3):
emitter.onNext(i)
time.sleep(1)

# emitter.onError(Exception("foo"))
emitter.onComplete()

frames = rx.Observable.create(lambda emitter: on_subscribe(emitter, video_url, 2))
mat_img = frames.map(featureextractor.FeatureExtractor.preprocess_image)
vect = mat_img.map(lambda img: fe.get_activations([img]))
words = vect.map(lambda vec: d.getWordsForBatch(vec, 40)) \
.flatMap(lambda wlist: rx.Observable.from_(wlist))
words = words.doOnNext(lambda w: log.info("words=%s" % w)).doOnError(lambda err: log.error("ERRRORRR %s" % err))
value = words.toList().blockingGet()
