Python numpy库版本不符合要求
执行OpenFace的训练脚本，遇到如下问题：

网上找到解决方法：RuntimeWarning: numpy.dtype size changed, may indicate binary incompatibility
是因为库版本不兼容的原因，具体到当前问题，就是numpy库的最新版本不符合要求，需要使用之前的版本
当前numpy库版本号是1.15.0
(openface) zhujian@zhujian-virtual-machine:~/openface$ conda list numpy
# packages in environment at /home/zhujian/software/anaconda/anaconda3/envs/openface:
#
# Name Version Build Channel
numpy 1.15.0 py27h1b885b7_0
numpy-base 1.15.0 py27h3dfced4_0
将它修改为1.14.5
(openface) zhujian@zhujian-virtual-machine:~/openface$ conda install numpy=1.14.5
Solving environment: done
## Package Plan ##
environment location: /home/zhujian/software/anaconda/anaconda3/envs/openface
added / updated specs:
- numpy=1.14.5
The following packages will be downloaded:
package | build

numpy-1.14.5 | py27h1b885b7_4 35 KB
numpy-base-1.14.5 | py27hdbf6ddf_4 4.1 MB
------------------------------------------------------------
Total: 4.1 MB
The following packages will be DOWNGRADED:
numpy: 1.15.0-py27h1b885b7_0 --> 1.14.5-py27h1b885b7_4
numpy-base: 1.15.0-py27h3dfced4_0 --> 1.14.5-py27hdbf6ddf_4
Proceed ([y]/n)? y

参考文章提出用pip的方式
sudo pip uninstall numpy
sudo pip install numpy==1.14.5
修改后就不再有上述问题弹出
