Deployment

Docker way

1. Install docker engine (actual instructions):

sudo apt update
sudo apt upgrade -y
sudo apt dist-upgrade -y
sudo apt autoremove -y

sudo apt install -y apt-transport-https ca-certificates curl gnupg lsb-release
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt update
sudo apt-get install docker-ce docker-ce-cli containerd.io

sudo systemctl status docker

sudo usermod -aG docker $USER
newgrp docker

2. Install NVIDIA Container Toolkit (actual instructions):

distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \
   && curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add - \
   && curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt update
sudo apt install -y nvidia-container-toolkit
sudo systemctl restart docker

3. Build docker image:

git clone https://github.com/osmr/tgchatbot.git
cd tgchatbot
docker build -t tgchatbot .

4. Run docker container (fill the token value):

docker run -it --rm --name=tgchatbot1 tgchatbot --token="<Your token>"

or

docker run -it --rm --gpus=all --name=tgchatbot1 tgchatbot --token="<Your token>" --use-cuda

Virtualenv way

NB: You need Python >= 3.7 due to requirements of the aiogram and SpeechBrain packages.

1. Install prerequisites:

apt-get update && apt-get upgrade -y && apt-get autoremove
apt-get install -y libsndfile1-dev ffmpeg

2. Install virtualenv (actual instructions):

sudo -H pip install --upgrade pip setuptools wheel
sudo -H pip install Cython
sudo -H pip install virtualenv

3. Clone repo, create and activate environment:

git clone https://github.com/osmr/tgchatbot.git
cd tgchatbot
virtualenv venv
source venv/bin/activate

4. Install dependencies:

pip install torch==1.9.1+cu111 torchaudio==0.9.1 -f https://download.pytorch.org/whl/torch_stable.html
pip install -r requirements.txt
pip install TensorFlowTTS==1.8
pip install huggingface-hub==0.0.17 six==1.16.0
pip install --upgrade numpy llvmlite numba typing-extensions h5py
pip install pytest
pip install .

5. Run tests:

pytest

6. Run the chatbot (fill the token value):

python -m tgchatbot.launch --token="<Your token>"
docker run -it --rm --name=tgchatbot1 tgchatbot --token="<Your token>"

or

python -m tgchatbot.launch --token="<Your token>" --use-cuda

7. Deactivate environment:

deactivate
