Installation

1. Get the code

First, clone this repo and cd into it. Then clone these codes:

git clone https://github.com/AndresPMD/Fine_Grained_Clf
git clone https://github.com/jeonsworld/ViT-pytorch
git clone https://github.com/allenai/kb
git clone https://github.com/matt-peters/allennlp.git

2. Create environment

conda env create -f env.yml
conda activate vit_kb

pip install -r exact_requirements.txt

cd allennlp; git checkout 2d7ba1cb108428aaffe2dce875648253b44cb5ba
pip install -e .
cd ..

cd kb
pip install -r requirements.txt 
python -c "import nltk; nltk.download('wordnet')"
pip install https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.0.0/en_core_web_sm-2.0.0.tar.gz
pip install -e .
cd ..

Dataset prepare

1. Download datasets

see README_datasets.md.

2. Put in `datasets/`

Usage

1. Train

python main.py -c CONFIG_PATH

for example:

python main.py -c configs/train_knowbert_attention_activity.toml

You can also pass parameters like this:

python main.py -c CONFIG_PATH --text_dir ./datasets/activity/texts --cfgs OUTPUT_DIR ./outputs NUM_EPOCHS 50 BATCH_SIZE_PERGPU 8

The parameters after "--cfgs" are config items in configs/*.toml

2. Test

python main.py -c TEST_CONFIG_PATH

Trouble Shootings

1

TypeError: ArrayField.empty_field: return type `None` is not a `<class 'allennlp.data.fields.field.Field'>`.

Solution:

pip install overrides==3.1.0

2

ModuleNotFoundError: No module named 'sklearn.utils.linear_assignment_'

Solution:

pip install scikit-learn==0.22.1

3

Error when run "pip install en_core_web_sm"

Solution:

conda install spacy-model-en_core_web_sm

4

if stuck when run pip install -r kb/requirement.txt, comment out the "git+git://" line in the kb/requirements.txt
