Question

我正在尝试创建条形图（使用Matplotlib）以保存在AWS S3存储桶中。它完全适用于我的笔记本电脑但是当我将代码上传到AWS Lambda（安装了正确的软件包）时，我收到了一个错误。这是代码：

import matplotlib.pyplot as plt
from boto3 import Session
import io

from datetime import date

months = [date(2018, month, 1).strftime('%b') for month in range(1, 13)]
filename = 'barplot.png'
BUCKET = 'my_bucket_name'

img_data = io.BytesIO()

counts = [
    [606, 124, 759, 998, 234],
    [762, 912, 639, 591, 135],
    [492, 92, 119, 1131, 999],
]

plt.figure()
plt.title('Fantastic Title Goes Here')
plt.xlabel('Timeline')
plt.ylabel('base count')

x1 = [2.0, 4.0, 6.0, 8.0, 10.0]
x2 = [x - 0.5 for x in x1]
x3 = [x + 0.5 for x in x1]

plt.xticks(x1, months)

plt.bar(x3, counts[2], width=0.4, color="#ff0000", label="Bar 3 Label")
plt.bar(x2, counts[1], width=0.4, color="#87CEEB", label="Bar 2 Label")
plt.bar(x1, counts[0], width=0.4, color="#F4A460", label="Bar 1 Label")

plt.legend()

plt.axis([0.5, 25, 0, 1500])
# NOTE saving to a file: plt.savefig(filename)

plt.savefig(img_data, format='png')
img_data.seek(0)


s3 = Session().client('s3')

response = s3.put_object(Body=img_data, Bucket=BUCKET, ContentType='image/png',
                         Key=filename, ACL='public-read')

我收到以下错误： ImportError：无法导入名称'multiarray'

这是错误Traceback：

ImportError:
Importing the multiarray numpy extension module failed. Most
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

Original error was: cannot import name 'multiarray'

显然，我试图联合卸载并重新安装numpy和matplotlib几次并没有成功。

Numpy没有使用AWS Lambda
