Dalle-At-Your-Service(ays): Lightweight Dalle Server using FastAPI

Configuration

Note any env vars with a None default value are needed to run the server.

Variable	Default	Type	Desc
DALLE_MODEL	"dalle-mini/dalle-mini/mega-1-fp16:latest"	str
VQGAN_REPO	"dalle-mini/vqgan_imagenet_f16_16384"	str
VQGAN_COMMIT_ID	"e93a26e7707683d349bf5d5c41c5b0ef69b677a9"	str
DEFAULT_NUM_PICS	3	int
WANDB_API_KEY	None	str
XLA_PYTHON_CLIENT_MEM_FRACTION	.85	float	fraction of gpu memory if preallocate is enabled
XLA_PYTHON_CLIENT_PREALLOCATE	false	turning this off reduces gpu memory usage

Development

Mandatory env vars are required from the configuration section in a .env file!

To kickstart the creation of that file, run

task env

Locally

Configure vscode debugger for live reload local build (you will need cuda and nvidia drivers):

{
  "configurations": [
    {
      "name": "Python: FastAPI",
      "type": "python",
      "request": "launch",
      "module": "uvicorn",
      "args": ["app.main:app", "--reload", "--log-level", "debug"],
      "jinja": true,
      "justMyCode": true,
      "envFile": "${workspaceFolder}/.env"
    },
  ]
}

Docker

Or, alternatively,

Build the image:

task build

Run:

Using a gpu:

task run

Using cpu only

task run-cpu

Development (live reload docker builds with gpu): Using gpu:

task dev -w

Using cpu:

task dev-cpu -w

Lint:

task lint
