cougar-or-not's Introduction

cougar-or-not

My first attempt at a machine learning API, using a pre-calculated model trained using iNaturalist data.

The resulting API is used by the @critter_vision Twitter bot, the source code for which can be found at https://github.com/natbat/CritterVision

The model is usa-inaturalist-cats.pth - an 83MB file.

The notebook inaturalist-cats.ipynb shows how I trained the model, using fastai.

cougar.py is a very tiny Starlette API server which simply accepts file image uploads and runs them against the pre-calculated model.

It also accepts a URL to an image, e.g. https://cougar-or-not.now.sh/classify-url?url=https://upload.wikimedia.org/wikipedia/commons/9/9a/Oregon_Cougar_ODFW.JPG

The Dockerfile means the entire thing can be deployed to Zeit Now or any other container hosting service.

Examples

cougar-or-not's Issues

`Internal Server Error`

I get this error Internal Server Error when I upload the image. Should I run it on a local server? Or it just works with Zeit?

Cannot run on macOs

Helo

Uploading 83MB file to GitHub

Not the issue really... Hi, how did you upload the 83MB file to GitHub? Best I can think of is split command, but it ends in chunks max of 25MB?

Docker build fails

I'm trying to build Docker image but I got the following error:

missing normalization

I think you should add normalization
cat_data = ImageDataBunch.from_name_re(
cat_images_path,
cat_fnames,
r"/([^/]+)_\d+.jpg$",
ds_tfms=get_transforms(),
size=299,
).normalize(imagenet_stats)
