How can I install python opencv on Heroku?

Question

I tried using this custom buildpack https://github.com/gimlids/heroku-buildpack-python-opencv

But compilation fails due to a 15 minute timeout.

I also tried setting COMPILE_TIMEOUT: 6000 but it Didn't help

Answer 1

要解决 heroku 上 buildpack 的 15 分钟编译时间限制，请使用heroku-anvil编译 slug。

Answer 2

I found a buildpack that worked well from a similar question about Heroku and OpenCV with Python . I tried to replicate Diogo's work and added a few additional steps to add ffmpeg support and documented the steps in a blog post: How to Install OpenCV on Heroku .

Answer 3

use a 'one-off' dyno (aka heroku run bash ) to compile, push the results to gihub (or store it anywhere else in the cloud), then use that url for your buildpack.

tl, dr; - avoid to re-compile each and every time.
