这是json文件
{"pre_trigger": 4, "sampling frequency": 1652, "record length": 15.0,

我不是一个理解编码的人,所以我不知道这个错误真正来自哪里。我正在运行一个命令下面的命令
daq = DAQ()
daq.load_setup('json.fname')
返回属性错误。json文件中没有单引号,所以我真的不知道问题出在哪里。下面是错误回调到的地方。你知道吗
def load_setup(self,fname='setup.json'):
"""
Opens the JSON file containing the setup parameters for the experiment.
Parameters
----------
fname : str
File that the parameters for the experiment were saved into (JSON file)
"""
import json
with open(fname, 'r') as setup_file:
setup_data = json.load(setup_file)
self.fs = setup_data['sampling frequency']
self.record_length = setup_data['record length']
self.sensors = setup_data['sensors']
self.parameters = setup_data['parameters']
self.pre_trigger = setup_data['pre_trigger']
您只是没有有效的JSON(Python代码没有任何问题)。您没有正确使用阵列功能。JSON数组如下所示:
它不是这样的(这就是你所拥有的以及为什么你会得到错误):
长话短说,您的列表项以逗号分隔,置于方括号内。以下是JSON的外观(
sensor
数组已修复,并且打印得很漂亮):我建议您始终保持JSON的打印效果(即使是在磁盘上),因为这样更容易阅读/理解。JSON格式的一部分吸引力在于,您可以轻松地将其视为一个人。你知道吗
在此修复之后,您发布的其余代码运行良好。你知道吗
嗯。你知道吗
