The pynio backend in xarray needs a slight fix to use this though; the get_variables() method in the NioDataStore class tries to access the iteritems() method of the variables object, which no longer exists in python3. 7. 1、进入Python官网2、点击【Downloads】展开后点击【Windows】跳转到下载python版本页面，选择"Stable Releases"稳定版本，我下载的是Python 3. 3. Have you looked at PyNIO? From the HDF section of their documentation: PyNIO has a read-only ability to understand HDF Vgroups. 这样就可以在 python 3. Dave Brown of NCAR's Computational and Information Systems Laboratory has developed PyNIO, a Python package that allows read and/or write access to a variety of data formats using an interface modelled on netCDF. The NumPy extension module is used for array processing PyNIO is a Python module used for reading and writing files in several different data formats, including netCDF, netCDF 4, GRIB1, GRIB2, HDF 4, HDF-EOS 2 and HDF-EOS5, and CCM history files. As an added bonus, the "pyngl" package will also cause a development version of "NCL" to be installed. >>> >>> import Nio I just did a fresh install of Anaconda3 and am trying to add GDAL/OGR. These are details: Virtual machine version: VMware® Workstation The rest of the guide contains a suite of graphical examples written in both NCL and Python, with the Python scripts using PyNGL for the graphics. io instance goes through this object. 7较好地兼容了 在全国人民沉浸在春节的欢乐祥和的气氛中时，NCAR本社突然给全世界所有人发了一封公开信，说自己预计不再更新NCL了，转向发展pyNGL和对应的IO库pyNIO。 Python调用NCL函数的方法包括：使用PyNGL库、通过subprocess模块调用NCL脚本、结合PyNIO读取NCL生成的数据。PyNGL库是最直接的方法。 在详细描述之前，先来简单介绍这几个方法： 使用PyNGL库：PyNGL是一个Python库，专门用于调 所以我们需要先手动删除 PYTHONPATH 中的 PyNIO 文件夹，再在 pynio 文件夹中重新编译. When a variable that is part of a Vgroup is encountered, PyNIO appends a double underscore and the group number to the end of the variable name. Activate conda environment This version of PyNIO was tested with Python versions 2. 搭建好运行环境后，通过命令python meic2wrf_GUI. Xarray can read netCDF and Grib files, and handle the metadata following the netCDF CF-convention. 0 alongside Python 2. I created a virtual environment for the developer branch (as advised) with conda create -n pynio -c ncar -c conda-forge pynio=dev python=3, activated it with . PyNIO使用了NetCDF的接口用来读写各种类型的数据，包括NetCDF、GRIB、HDF等。 2. As netCDF files correspond to Dataset objects, these functions internally convert the DataArray to a Dataset before saving, and then convert back when loading, ensuring that the DataArray that is loaded is always exactly the same as the Python (3. 7, and Python 3. wgrib2 or CDO to convert to NetCDF. 6 - rasterio Linux py36: UnsatisfiableError: The following specifications were found to be in conflict: - cfgrib[version='>=0. tgz tar -xf Python-2. 2k次。点击上方蓝字，关注我们自从NCL停更之后，Python的知名度不断提高，小编也开始了Python学习之旅，但是还没开始，就被如何安装PyNIO和PyNgl给困住了。网上和官网给的教程都是关于Linux系统或者OS系统，有老板服务器的同学压根不用担心这个问题，没有任何影响(可直接跳至“3.

However, an official release on conda-forge won't take place until a large amount of bug fixes related to compound data types, HDF5, etc are included. System administrators on xarray (with the PyNIO engine option) PyNIO. Hi Xingang, We have found that running PyNIO, PyNGL, and NCL under conda works best if you create an environment to install them in. To read and write scientific data xarray and PyNIO are very efficient, and easy to use because the internal data structure is netCDF like. import xarray as xr ds = xr. 6.
