AWS Lambda上的PyteSeract:tesseract未安装或不在您的路径中

Question

lambdaaws:python3.8

ARN测试：

• arn:aws:lambda:eu-west-3:770693421928:图层：Klayers-python38-pytesseract:15
• arn:aws:lambda:eu-west-3:770693421928:图层：Klayers-python38-pytesseract:16
• arn:aws:lambda:eu-west-3:770693421928:图层：Klayers-python38-pytesseract:17

lambdaaws:python3.7

ARN测试：

• arn:aws:lambda:eu-west-3:113088814899:图层：Klayers-python37-pytesseract:13

lambda_function.py：

import json
import pytesseract
from PIL import Image


def lambda_handler(event, context):
    try:
        body = {
            "text": pytesseract.image_to_string(Image.open('random_text.png')),
        }
    except Exception as e:
        body = str(e)

    response = {
        "statusCode": 200,
        "body": json.dumps(body)
    }


    return response

导入所有内容时没有错误，当我尝试使用pytesseract.image_to_string()执行操作时会出现错误

因为在Python3.7/3.8中导入了相应的ARN工作，所以我认为这个错误非常特殊，并且与pytesseract有关。 但是为什么不能由ARN来处理呢？ 我看到另一篇关于教程的帖子，但我总是被这个准确的错误所困扰：tesseract is not installed or it's not in your PATH

Answer 1

But why isn't it handle by the ARN ?

该层仅用于实际tesseract二进制文件周围的pytesseract包装。它不附带tesseract程序

因此，您必须自己为lambda环境构建tesseract二进制文件，并将其与lambda函数捆绑在一起。一种方法是显示here
