“生态代码库”未找到

Question

我已经使用Conda安装了eccodes库，但是当我试图在ecCodes中导入它时，我得到了“无法找到ecCodes库”。

为什么我要得到这个错误，我如何解决它？我认为Python不知道在哪里可以找到库。

我用的是在这里找到的命令。那是,

conda install -c conda-forge eccodes
pip3 install --upgrade eccodes

我用的是Windows机器。

Answer 1

在询问了同事之后，我们通过运行代码找到了解决方案

import ecmwflibs

现在电子编码已经被认可了

他发现这是因为错误消息是由~/Anaconda3/Lib/site-packages/gribapi/bindings.py中的脚本引发的。

lib = ffi.dlopen(library_path)

Answer 2

我不会在这里惹皮普的。Conda提供了编译后的库(eccodes)和Python绑定(python-eccodes)。后者将前者列为依赖项，因此应该足以使用：

conda install -c conda-forge python-eccodes
