网上找了很多原因，都没解决，自己看看其实很简单。
h5py安装没问题。所有要么路径问题，要么程序问题：
路径应该没问题，看程序
File "/home/chengle/a_program/pointnet/utils/data_prep_util.py", line 84, in save_h5
dtype=data_dtype)
data_prep_util.py第84行
h5_fout = h5py.File(h5_filename)
使用手册写法
hf = h5py.File('data.h5', 'w')
所以写成
h5_fout = h5py.File(h5_filename, 'w')
解决
应该是程序没有打开写入（w）权限，
