QUESTION

How can I ensure repeatability while parallelizing a randomly seeded experiment?

Asked 2018-Oct-09 at 10:55

I'm using Mydia to extract random frames from videos. Because I have a lot of videos, I want to parallelize this workflow while maintaining repeatability. mydia.Videos accepts a random seed, which is important for ensuring repeatability. Now I need to work on the parallelization piece.

Given n videos and a random seed, r, how can I ensure that the extracted frames for each video is the same regardless of the number of workers? I'm particularly interested in the algorithmic component, not necessarily the code.

My initial thought was to use multiprocessing.Pool. However, there will be a race condition in sampling the frames if the processes' completion times are non-determinstic; i.e., if proc 1 takes longer than proc 0, the sampled frames from the Videos class will be different than if proc 0 takes longer than proc 1.

My solution is a bit unorthodox because it's library-specific. Mydia allows to pass the frames to extract in lieu of forcing the Videos client to sample directly. This affords me the opportunity to precalculate the frames to sample in the parent process. By doing this, I can "mock" the randomness in the subprocesses by instantiating a new Videos with those frames. For instance:

How to align 2 different charts?

Asked 2017-Feb-24 at 11:05

I have 2 different charts next to each other. The first chart has an x-axis, the second chart doesn't:

How can I make them both the same height?

This is the desired output:

Here is some sample code, how I created my charts:

ANSWER

Answered 2017-Feb-24 at 11:01

The problem is caused by missing bottom labels on second graph. To make them the same height you could do the following:

Define height of first graph 350, and 325 of second graph inside JS code
Modify CSS to align graphs vertically to top

Adding 2nd Y Axis

As described in this example, I added an additional value axis and positioned it on the right:

You have to assign a graph to the second Y Axis or else they'll all use the first valueAxis. This is done through the yAxis property in the XY chart:
