https://stackoverflow.com/questions/75495360/how-to-deploy-a-fastapi-endpoint-using-pythonanywhere
I have been trying to deploy EasyOCR (it's fine if it works on CPU) with FastAPI endpoints such that anyone can use it via https POST request. It runs fine on my local host but when I have been facing challenges in deploying it using pythonanywhere. I added the additional requirements like pip install easyocr, pip install python-multipart==0.0.5.
The following is my code-
import io
import logging
import re
from fastapi import FastAPI, APIRouter, Request, File, UploadFile
from fastapi.responses import FileResponse, StreamingResponse
import easyocr
import PIL
from PIL import Image, ImageOps
import numpy
app = FastAPI()
router = APIRouter()
ocr = easyocr.Reader(["en"])
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger("ocr")
@app.get("/")
async def root():
return {"message": "Hello World"}
@app.post("/ocr")
async def do_ocr(request: Request, file: UploadFile = File(...)):
if file is not None:
imgFile = numpy.array(PIL.Image.open(file.file).convert("RGB"))
res = ocr.readtext(imgFile)
# return array of strings
return [item[1] for item in res]
return {"error": "missing file"}
app.include_router(router)
if __name__ == "__main__":
import uvicorn
uvicorn.run(app)
I am getting the error in the logs-
During handling of the above exception, another exception occurred:
