AttributeError：“模块”对象没有属性“转储”（检查文件）

Question

我正在尝试使用 JSON 文件配置帐户，但它给出了 AttributeError。我检查了它正在导入的 JSON 的位置。这几天我一直在摆弄这个问题，我似乎找不到这个问题的根源。 JSON 中的__init__.py file 中定义了转储函数。我是 python 新手，所以如果我忽略了这个错误或者存在格式问题，我想提前道歉。谢谢。

输入：

import sys
import json
import time
import Adafruit_GPIO.SPI as SPI
import Adafruit_MAX31855.MAX31855 as MAX31855

__Author__ = 'Zach'

CLK = 11
DO = 25

sensor1 = MAX31855.MAX31855(CLK, 13, DO)
sensor2 = MAX31855.MAX31855(CLK, 29, DO)
sensor3 = MAX31855.MAX31855(CLK, 05, DO)
sensor4 = MAX31855.MAX31855(CLK, 06, DO)
sensor5 = MAX31855.MAX31855(CLK, 20, DO)
sensor6 = MAX31855.MAX31855(CLK, 21, DO)
sensor7 = MAX31855.MAX31855(CLK, 12, DO)
sensor8 = MAX31855.MAX31855(CLK, 16, DO)

try:
    config_data = open('/home/pi/TempMonitor/picloud_config.json').read()
    config = json.loads(config_data)

    raise

Answer 1

我注意到的一件事是，您的输出表明 temp1 是 NAN，这意味着不是数字。我认为您的temp1 = float(sensor1.readTempC()) 出了点问题。修复此问题也可能会无意中修复您的 JSON 错误，因为 api.Metric.send 可能（很可能）假定输入是正确的（而不是 NAN）。

Answer 2

所以问题是 Datadog 目录中有一些文件进入了错误的文件夹。经过一些卸载和重新安装目录。我让它工作得很好。
