正在尝试从位于s3中的zip文件中在AWS lambda(Python 3.6(中运行函数。
遵循各个位置的说明(AWS文档，其他博客等(。但是，我似乎在加载numpy时在某个地方出错。
有些人可以帮忙吗？
这是我上传到s3 -zip文件
的zip文件另外，当我测试zip-
时，错误日志返回以下内容。START RequestId: b004d192-17e7-11e8-8323-bb9e005088cc Version: $LATEST

likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all files not under version control). Otherwise reinstall numpy.
Original error was: cannot import name 'multiarray'

我知道我在某个地方犯了一些愚蠢的错误，但是根本无法弄清楚什么和何处 - 有人可以帮助解释相同吗？
以下是我收到的AWS支持答复：
I seem to have managed to get the function working. Please see below the steps which I have followed. I initially tried adding the dependancies using the virtualenv method but got the same errors as your were getting. Then I tried using the method described at the below link using an EC2 instance launched with the same execution environment as Lambda and pip. Please can you give this a try.
https://docs.aws.amazon.com/lambda/latest/dg/lambda-python-how-to-create-deployment-package.html
Create an EC2 instance using the AMI mentioned in the below document - AMI name: amzn-ami-hvm-2017.03.1.20170812-x86_64-gp2.
Go to EC2 console, Launch Instance and click Community AMI’s, then paste the AMI name - amzn-ami-hvm-2017.03.1.20170812-x86_64-gp2 - into the search box and hit enter. Select the AMI and continue with the EC2 instance setup.
https://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html
Once the instance has been created, ssh into the instance and follow the steps below.
1. Create working directory
mkdir lambda
cd lambda/
2. Install required packages and dependancies
sudo yum -y groupinstall "Development Tools"
sudo yum install python27-devel python27-pip gcc
sudo pip install numpy -t ~/lambda/
sudo pip install sqlalchemy -t ~/lambda/
sudo pip install pandas -t ~/lambda/
3. SCP the Lambda function file to ~/lambda directory on EC2 instance or create a lambda_function.py file in the ~/lambda directory
e.g.
scp -i Key.pem lambda_function.py ec2-user@ec2-xx-xx-xxx-xxx.amazonaws.com:~/lambda/lambda.zip
or
nano/vi lambda_function.py and paste the code into the terminal
from the ~/lambda directory run - zip -r "lambda.zip" *
4. Upload the lambda.zip file to S3 using the AWS CLI or SCP the file to you local machine and upload to S3 from the S3 console.
e.g.
Copying a local file to S3
The following cp command copies a single file to a specified bucket and key:
aws s3 cp test.txt s3://mybucket/test2.txt
https://docs.aws.amazon.com/de_de/cli/latest/reference/s3/cp.html
or
scp -i Key.pem ec2-user@ec2-xx-xx-xxx-xxx.amazonaws.com:~/lambda/lambda.zip ~/lambda.zip
5. Add file to Lambda from S3 and choose Python2.7 as runtime.
6. Test function. No error returned, see output below.
