Currently, I have only tested this on Linux (Arch Linux and Ubuntu 18.04 LTS)
To run this repo, you need the following:
- A modern c++ compiler (newer version of gcc and clang seem to work, although gcc 9 has issues)
- Libtorch
- Sentencepiece
- Boost
- nlohmann json
- Other Tokenizers (not implemented yet)
To run the sample, you'll additionally need:
Below are a set of scripts that will download and install the example dataset, a pretrained model, and the various c++ libraries required for this repo. I am assuming anyone using this has a preexisting install of conda and boost already installed. If you already have the c++ libraries installed, you can look at compile.dev and set the appropriate environmental variables to the locations of your local libraries. There are some requirements for the above mentioned libraries and you obviously need to install those as well. You can look at my CI build to see what it would take to run this library from a clean Ubuntu 18.04 LTS system.
Right now I don't plan on supporting OSX or Windows, although I suspect this could run on OSX if you install all the required libraries manually. Especially for Windows, I don't have the time nor a Windows system to test this on. Feel free to make a PR if you want OSX / Mac support.
Currently, I have only test this with an ALBERT model on a simple classification task (sentiment analysis). One should be able to use any of the sentencepiece-tokenized models with fairly few modifications and hopefully, I'll be adding the other tokenizers and tasks soon.
ALBERT model pretrained on SST-2 - download and unzip it (i.e. in a folder called models).

I used the transformers library to train the sentiment analysis example with a mostly default parameters. Here's the command I ran:
# clone transformers repo for training scripts
git clone https://github.com/huggingface/transformers.git
# single GPU training
python transformers/examples/run_glue.py --task_name sst-2 --data_dir data/SST-2 --model_type albert --model_name_or_path albert-base-v1 --save_steps 5000 --output_dir output --do_train --do_eval --evaluate_during_training --per_gpu_train_batch_size 32 --overwrite_output_dir
