将pandas/scikit-learn包添加到项目以在AWS lambda中使用的正确方法是什么

Question

我正在执行以下文档中提到的所有步骤:http: //docs.aws.amazon.com/lambda/latest/dg/lambda-python-how-to-create-deployment-package.html

我使用亚马逊linux的amazon的ec2来构建软件包.

我也尝试过https://markn.ca/2015/10/python-extension-modules-in-aws-lambda/中提到的步骤.

以下是将包上传到AWS lambda并运行时出现的错误:

START RequestId: cbfe0762-8f1b-11e5-9a1d-49fb4d3a0d13 Version: $LATEST
Unable to import module 'test': No module named pandas

该错误没有给出任何具体的指示.

嗨@maxymoo

我只是创建内容的zip.不是包含.py文件的文件夹.当我尝试使用我的.py文件添加"请求"包时,它工作正常.现在当我尝试使用我的.py文件添加"pandas"包时,它会给我上面的错误.

以下是我遵循的步骤:

1. 运行amazon linux连接到ec2.

2. 启动virtualenv

3. 使用"pip install pandas"安装pandas

4. 转到"/home/ec2-user/t1/lib/python2.7/site-packages"目录

5. 获取"/home/ec2-user/t1/lib/python2.7/site-packages"的所有内容将我的test.py文件添加到其中并创建zip文件

6. 将zip文件上传到amazon lambda

7. 运行测试

我收到以下错误:

START RequestId: feee67de-8f2f-11e5-bc34-bd42a1d7326b Version: $LATEST
Unable to import module 'test': No module named pandas

END RequestId: feee67de-8f2f-11e5-bc34-bd42a1d7326b

test.py的内容是:

import json

import requests

import pandas as pd


print('Loading function')


def lambda_handler(event, context):

    #print("Received event: " + json.dumps(event, indent=2))

    print("value1 = " + event['key1'])

    print("value2 = " + event['key2'])

    print("value3 = " + event['key3'])

    return event['key1']  # Echo back the first key value

    #raise Exception('Something went wrong')

以下是zip文件中的文件:
