使用Python Anaconda包grib_api时的ImportError

时间:2016-09-30 08:59:02

标签: python anaconda grib-api

我正在尝试使用ECMWF GRIB_API从Python访问GRIB文件。我收到此错误

onReceivedError

一行代码:)

Traceback (most recent call last): File "/home/martin/markj/JustImportGRIB.py", line 1, in <module> from gribapi import * ImportError: No module named gribapi

我正在使用Anaconda Python 2.7.12,Linux Centos 64位,作为用户安装,如果相关的话,系统Python(2.6)不在路径上,而不是将Anaconda添加到路径中。我从Pingu Carsti channel安装了GRIB_API,这是谷歌的热门搜索。 conda安装没有报告任何错误。

from gribapi import *

我发现some bug reports有关此错误是由ECMWF GRIB_API中的错误引起的,但我对Anaconda(或Python)的了解不足以了解如何应用{{3} }。

我使用pygrib在Python中读取GRIB文件。我已成功将其安装在conda虚拟环境中(Ubuntu 16.04上的Miniconda2)。这对我有用:

  1. 为pygrib安装系统依赖项:

    sudo apt-get install libjpeg9

    sudo apt-get install libgrib-api-dev

  2. 从conda-forge频道安装pygrib和ecmwf_grib。

    conda install -c conda-forge pygrib ecmwf_grib

尝试使用 python-eccodes 进行conda-forge构建(注意:那不是 eccodes ,这是C库)。

如何构建:https://github.com/conda-forge/python-eccodes-feedstock/blob/master/recipe/meta.yaml

ECMWF的ecCodes库是其GRIB API的下一个版本,与旧的GRIB API非常相似。
