TypeError:python cdsapi中不可调用“tuple”对象

Question

我试图在python的cdsapi模块的帮助下检索数据。但是给出了以下错误

我已按照以下链接中的建议注册并安装了cdsapi客户端密钥

https://cds.climate.copernicus.eu/api-how-to

我的简单代码snipet如下所示

import cdsapi
cds = cdsapi.Client()
cds.retrieve('reanalysis-era5-pressure-levels', {
"variable": "temperature",
"pressure_level": "1000",
"product_type": "reanalysis",
"date": "2017-12-01/2017-12-31",
"time": "12:00",
"format": "grib"
}, 'download.grib')

这是怎么回事

Answer 1

问题解决了。 ~/.cdsapirc文件中存在问题，需要正确配置。 配置后，程序运行良好

Answer 2

如果您已登录，instructions中不太明显，但在.cdsapirc文件的key字段下，您需要用户ID和api密钥，如下所示：

key: $user_id:$api_key

我也遇到了这个问题，通过添加我的用户ID解决了这个问题

Answer 3

我也有同样的问题。登录哥白尼网站并接受以下URL中的许可条款后，我的问题得到解决：
