【问题描述】:
在安装Fuel machine learning 库时,我遇到了一些依赖问题:
alvas@ubi:~$ pip install --upgrade git+git://github.com/mila-udem/fuel.gitYou are using pip version 7.1.0, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Complete output from command python setup.py egg_info:

.. ERROR:: Could not find a local HDF5 installation.
You may need to explicitly state where your local HDF5 headers and
library can be found by setting the ``HDF5_DIR`` environment
variable or by using the ``--hdf5`` command-line option.
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-wMS1d3/tables
然后在我完成之后(Installing h5py on an Ubuntu server):
sudo apt-get install libhdf5-dev
sudo HDF5_DIR=/usr/lib/x86_64-linux-gnu/hdf5/serial/ pip install h5py
然后我还必须更新我的 cython:
sudo pip install cython
我的问题不是关于如何解决安装问题,而是这个命令是什么意思?
sudo HDF5_DIR=/usr/lib/x86_64-linux-gnu/hdf5/serial/ pip install h5py
指定 HDF5_DIR 有什么作用?
为什么燃料依赖项没有自动从安装:
- https://github.com/mila-udem/fuel/blob/master/requirements.txt
- https://github.com/mila-udem/fuel/blob/master/setup.py
我应该如何从fuel 更新 setup.py 以便它可以自动 pip 安装依赖项?
