问题描述

我正在运行代码以从带有 xarray 的 URL 读取 NetCDF 文件中的数据.当我在调试模式下在 Eclipse/PyDev 中运行此代码时，我看到在作为普通 Python 运行或从命令行或作为 Jupyter 笔记本的单元启动时不会发生的错误.

I'm running code to read data from a NetCDF file from a URL with xarray. When I run this code in Eclipse/PyDev in debug mode I am seeing errors that don't happen when launching as a normal Python run or from the command line or as cells of a Jupyter notebook.

在代码中包含 import xarray 时出现以下错误:

I get the following error when I include an import xarray in my code:

 NameError: name 'dict_pop' is not defined

我正在使用安装在 Python 3.5.3 (Anaconda) 上的最新/最新版本的 xarray 和 Pandas.

I'm using recent/latest versions of xarray and pandas installed on Python 3.5.3 (Anaconda).

我在使用 'import pandas' 语句时也遇到了同样的错误，所以这可能与 pandas 相关，因为 xarray 内部依赖于 pandas.

I get the same error with an 'import pandas' statement as well, so this may be pandas related instead since xarray depends upon pandas internally.

安装包在Anaconda中如下图所示:

The packages are installed in Anaconda as shown below:

$ 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，我可以在命令行和/或 Jupyter 笔记本中使用导入的 pandas 和 xarray 运行此代码，这仅在我以调试模式在 Eclipse/PyDev 中启动代码时发生(常规 Python 运行)按预期工作).

Again I can run this code with the imports of pandas and xarray with no issue from the command line and/or within a Jupyter notebook, this only happens when I launch the code in Eclipse/PyDev in debug mode (regular Python run works as expected).

我用来测试的示例 Python 代码:

Example Python code I'm using to test this:

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

谁能给点建议?提前感谢您的任何建议.

Can anyone advise? Thanks in advance for any suggestions.
