iNaturalist_Competition

Script to classify images of plants and animals with the image-based species recognition models created in the context of the paper by Van Horn et al. 2021, benchmarking different kinds of models created on basis of the dataset of the iNaturalist 2021 Comptetition. The code was extracted from this repository by deblagoj as a contribution to the iNaturalist 2017 Competition.

How-To

1. (recommended but not absolutely necessary) create and activate own (conda) environment

2. install packages

pip install torch torchvision 

2.1 Actually this should work, otherwise you can also use the provided conda environment file environment.yml. Run in the repository:

conda env create -f environment.yml

3. Clone this repository

git clone https://github.com/EibSReM/iNaturalist_Competition.git

and change to respective directory

4. Download pretrained models from the paper here (5,6 GB), mentioned in the papers repository.

5. Unzip file with pretrained models (probably needs to be unzipped twice: first time the .tar.gz file, sedondly the .tar file in the unzipped folder from the previous step)

6. Adapt path to pytorch model in the inference.py script (we used the model in: cvpr21_newt_pretrained_models\cvpr21_newt_pretrained_models\pt\inat2021_supervised_large_from_scratch.pth.tar)

7. Adapt path to images (folder) in the inference.py script

8. Run script

python inference.py

9. Find results in Output.txt

Runtime

Classifying 258 images, the script run 81.02 seconds on a Windows 10 notebook with the following hardware specifications:

• Intel(R) Core(TM) i7-8565U CPU @ 1.80GHz 1.99 GHz
• 20 GB Ram
