对于python，安装hdf5/netcdf4

Question

在Linux Mint 17.1上执行此操作。

当我尝试的时候：

pip install hdf5

我得到了错误

"Could not find a version that satisfies the requirement hdf5 (from versions: ) No matching distribution found for hdf5"

从长远来看，我正在尝试安装netcdf4，但在安装hdf5之前，我无法做到这一点。假设从上周我尝试使用netcdf4开始，我应该使用pip install netcdf4，err hdf5...at，至少在hdf5的情况下。

如果我尝试pip install h5py，我得到的消息是：

Requirement already satisfied (use --upgrade to upgrade): h5py in ./anaconda3/lib/python3.5/site-packages Requirement already satisfied (use --upgrade to upgrade): numpy>=1.6.1 in ./anaconda3/lib/python3.5/site-packages (from h5py) Requirement already satisfied (use --upgrade to upgrade): six in ./anaconda3/lib/python3.5/site-packages (from h5py)

然而，如果我继续尝试pip install netcdf4，它会出现并说：

Collecting netcdf4 Using cached netCDF4-1.2.3.1.tar.gz Complete output from command python setup.py egg_info: Package hdf5 was not found in the pkg-config search path. Perhaps you should add the directory containinghdf5.pc‘到PKG_CONFIG_PATH环境变量No package 'hdf5’found cython 0.23.4 found ...正在从setup.cfg读取...

ValueError: did not find HDF5 headers

----------------------------------------

命令"python setup.py egg_info“在/tmp/pip-build-pq3yt4ek/netcdf4/`中失败，错误代码为1

当我搜索文件时，我没有找到hdf5.pc文件。

h5py和hdf5有什么区别吗？我是否必须从单独的文件编译和安装hdf5，或者我可以通过pip安装。

我必须做什么才能同时安装hdf5和netcdf4？

Answer 1

您需要为您的Linux发行版安装HDF5库。在Ubuntu中是：

sudo apt-get install libhdf5-serial-dev netcdf-bin libnetcdf-dev

参见this link。

Answer 2

我在Debian8中也遇到过同样的问题。为了解决这个问题，我以根用户的身份安装库，然后将串行头链接到hdf5库中的一个包含目录，导出HDF_DIR路径并安装netCDF4：

# apt-get install -y libhdf5-dev libnetcdf-dev
# ln -s /usr/include/hdf5/serial /usr/include/hdf5/include
# export HDF5_DIR=/usr/include/hdf5
# pip install netCDF4

Answer 3

我在macOS Catalina下也遇到了同样的错误。Had必须安装来自Homebrew的hdf5和netcdf4包：

brew install hdf5 netcdf4

之后，pip3 install netcdf4运行得很好。
