今天在执行一个用到hdf5的python脚本时，遇到如下错误
Warning! ***HDF5 library version mismatched error***
The HDF5 header files used to compile this application do not match
the version used by the HDF5 library to which this application is linked.
Data corruption or segmentation faults may occur if the application continues.
This can happen when an application was compiled by one version of HDF5 but
linked with a different version of static or shared HDF5 library.
You should recompile the application or check your shared library related
settings such as 'LD_LIBRARY_PATH'.
You can, at your own risk, disable this warning by setting the environment
variable 'HDF5_DISABLE_VERSION_CHECK' to a value of '1'.
Setting it to 2 or higher will suppress the warning messages totally.
Headers are 1.8.11, library is 1.8.9

昨天还好好的，今天怎么就出现了问题。回忆了一下好像昨天更新了anaconda，可能导致了冲突，经查看，确实如此。Anaconda中安装的hdf5库是1.8.9的， 而之前通过pip intall h5py库应该就是1.8.11的， 一山不容二虎，于是把旧版本删除了
sudo pip uninstall h5py
按下回车，果然在系统自带的python下有以前的h5py版本
