使用xr.open_mfdataset时报错Process finished with exit code -1073741571 (0xC00000FD)

问题报错

当想要使用xr.open_mfdataset读取多个nc文件时，输入

files = '...\\201901-201906\\*.nc'
dataset_AVISO = xr.open_mfdataset(files,parallel=True)

运行后出现报错：

Process finished with exit code -1073741571 (0xC00000FD)

问题分析

debug后，出现报错：

从报错可知出错原因在于： did not find a match in any of xarray’s currently installed IO backends [‘netcdf4’, ‘scipy’]. Consider explicitly selecting one of the installed engines via the engine parameter, or installing additional IO dependencies
但是博主已经安装了netcdf4和scipy两个库，在看到网友分享的方案后，改成

dataset_AVISO = xr.open_mfdataset(files,engine='netcdf4')

仍然不成功。

解决方法

在一番尝试后，最后发现只要修改成这样，代码即可运行成功：

dataset_AVISO = xr.open_mfdataset(files)
