NCO/pynco:ncks命令无法找到/移动文件,文件存在

pynco nco netcdf4 netcdf python

James Adams · 技术社区 · 7 年前

我正在使用 pynco 运行 ncks Python脚本中的命令。尝试在 nco_fl_mv() 功能:

$ C:/home/Anaconda3/Library/bin/ncks --dmn=lon,0,28,1 --output=C:/home/data/nclimgrid/201801_nclimgrid_dsd/work/lowres_nclimgrid_tavg_slice00.nc C:/home/data/nclimgrid/201801_nclimgrid_dsd/lowres_nclimgrid_tavg.nc
The system cannot find the path specified.
ncks: ERROR nco_fl_mv() unable to execute mv command "move C:/home/data/nclimgrid/201801_nclimgrid_dsd/work/lowres_nclimgrid_tavg_slice00.nc.pid11800.ncks.tmp C:/home/data/nclimgrid/201801_nclimgrid_dsd/work/lowres_nclimgrid_tavg_slice00.nc"

但是,文件似乎存在:

$ ls -l C:/home/data/nclimgrid/201801_nclimgrid_dsd/work/lowres_nclimgrid_tavg_slice00.nc.pid11800.ncks.tmp 
-rw-r--r-- 1 James.Adams Domain Users 2.9M Feb  9 13:45 C:/home/data/nclimgrid/201801_nclimgrid_dsd/work/lowres_nclimgrid_tavg_slice00.nc.pid11800.ncks.tmp

当我调试pynco模块时,我可以看到nco中的cmd对象。py(第263行)如下所示:

<class 'list'>: ['C:\\home\\Anaconda3\\Library\\bin\\ncks', 
                 '--dmn=lon,0,28,1', 
                 '--output=C:/home/data/nclimgrid/201801_nclimgrid_dsd/work/lowres_nclimgrid_tavg_slice00.nc',
              ` 
                 'C:/home/data/nclimgrid/201801_nclimgrid_dsd/lowres_nclimgrid_tavg.nc']`

也许这是权限问题?我正在使用安装在Windows机器上Anaconda上的NCO/pynco。这发生在命令行(vanilla NCO)以及使用pynco NCO包装器的脚本中。

我建议您自己尝试从命令行执行失败的底层命令,并报告是否/如何/是否需要修改它才能成功,即尝试以下操作

move C:/home/data/nclimgrid/201801_nclimgrid_dsd/work/lowres_nclimgrid_tavg_slice00.nc.pid11800.ncks.tmp C:/home/data/nclimgrid/201801_nclimgrid_dsd/work/lowres_nclimgrid_tavg_slice00.nc

您还可以尝试将--no\u tmp\u fl开关添加到NCO命令,因为这样可以避免权限问题。
