Paint AI Bot

A Line bot who paints your images as paint from famous painters using neural style transfer. You can also play games and chat with it.

Try it now

It's now deployed on https://gnsjhenjie.tech/pbot/ as "名畫產生器-啾啾".

Requirements

• GCP Cloud Run (or other services that can run Docker)
  (1 vCPU and 160 Mib memory is sufficient for normal usage)

• At least one server with high CPU performance with Python3.7 (the performance decides the speed of generating images)

• Firebase Firestore

• GCP Cloud Storage

Deployment

For Cloud Run

Build the whole project as a container

gcloud config set project YOUR-PROJECT-ID
gcloud builds submit  --tag gcr.io/$GOOGLE_CLOUD_PROJECT/paint-ai-bot:0.0.1

Then, run the container image on Cloud Run with the below environment variables set.

• LINE_CHANNEL_ACCESS_TOKEN: the channel access token of your Line bot.
• LINE_CHANNEL_SECRET: the channel secret of your Line bot.
• USER_INFO_GS_BUCKET_NAME: the name of the bucket in your GCP cloud storage.

(For more instructions, see GCP docs and Line developer docs)

If you are not running the container in GCP, you may need to change some code to specify the key of your GCP service account to access Firestore and Cloud Storage.

For high CPU performance server(s)

You can run multiple high CPU performance servers.

pip install -r requirements.txt
python server.py

Make sure you execute server.py in Python3.7 with the below environment variables set.

• CRED_PATH: the credential(key) json file of your GCP service account.
• USER_INFO_GS_BUCKET_NAME: the name of the bucket in your GCP cloud storage.
• ITERATION_TIMES: the iteration times of the style transfer process.
  (320 is recommended for basic usage, and 1000 for those who pursue perfect effect)
• LINE_CHANNEL_ACCESS_TOKEN: the channel access token of your Line bot.
• DELTA: For those who just run one server.py process, set it to 0. If you run server.py in more than one server(or process), set it to 0, 3, 6, 9... respectively. (The delta is the pause time to avoid different server(process) dealing with the same task)
