ImportError: libmkldnn.so.0: cannot open shared object file: No such file or directory_没有规则可制作目标 libmkldnn.so.0

错误：

>>> import caffe
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/kzl/caffe/python/caffe/__init__.py", line 37, in <module>
    from .pycaffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, RMSPropSolver, AdaDeltaSolver, AdamSolver
  File "/home/kzl/caffe/python/caffe/pycaffe.py", line 49, in <module>
    from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, \
ImportError: libmkldnn.so.0: cannot open shared object file: No such file or directory

解决办法：

1.ibmkldnn.so.0在caffe安装目录/external/mkldnn/install/lib/

在该目录下：tree

.
├── libmkldnn.so -> libmkldnn.so.0
├── libmkldnn.so.0 -> libmkldnn.so.0.9.0
└── libmkldnn.so.0.9.0

0 directories, 3 files

接下来：把 libmkldnn.so.0.9.0 复制到 /usr/lib/下，然后仿照设置链接就好，

sudo cp libmkldnn.so.0.9.0 /usr/lib/libmkldnn.so.0.9.0
cd /usr/lib
sudo ln -s libmkldnn.so.0.9.0 libmkldnn.so.0
sudo ln -s libmkldnn.so.0 libmkldnn.so
sudo ldconfig

然后就解决了这个问题。
