Question

我正在运行代码，使用xarray从URL读取NetCDF文件中的数据。当我在Eclipse / PyDev中以调试模式运行此代码时，我发现在以普通Python运行或从命令行或作为Jupyter笔记本的单元格启动时不会发生错误。

当我在代码中包含import xarray时出现以下错误：

 NameError: name 'dict_pop' is not defined

完整堆栈跟踪如下所示：

我正在使用Python 3.5.3（Anaconda）上安装的最新/最新版本的xarray和pandas。

我也会在'import pandas'语句中得到同样的错误，所以这可能与pandas相关，因为xarray在内部依赖于pandas。

软件包安装在Anaconda中，如下所示：

$ conda list pandas
# packages in environment at C:\home\Anaconda3:
#
pandas                    0.20.3                   py35_1    conda-forge

$ conda list xarray
# packages in environment at C:\home\Anaconda3:
#
xarray                    0.9.6                    py35_0    conda-forge

同样，我可以使用pandas和xarray的导入来运行此代码而不会出现命令行和/或Jupyter笔记本中的问题，这只发生在Eclipse / PyDev中以调试模式启动代码时（常规Python运行）按预期工作。）

示例Python代码我用来测试它：

import sys
import xarray as xr

if __name__ == '__main__':

    try:

        # get the command line arguments
        input_netcdf_url = sys.argv[1]
        ds = xr.open_dataset(input_netcdf_url)

    except:

        raise

任何人都可以提供建议吗？提前感谢任何建议。

升级到5.9.2 ......这是固定女巫提示新版本的关键问题之一。
