Caffe installation process record under ubuntu18.04

Reference article:
Ubuntu16.04 Caffe installation steps record (super detailed)
Ubuntu 18.04 configuration OpenCV 4.2.0
Caffe - Ubuntu installation and problem solving

Refer to the above three blogs and record my own steps:
My CUDA10.0 and gcc have been installed.

1. Installation dependencies

2. Download opencv

My CUDA version is 10.0, I chose to install opencv3.4.0

Download opencv from the official website http://opencv.org/releases.html (select source).

Attach Baidu network disk link: https://pan.baidu.com/s/1H8VOa9C8sDbWh19R4-e-AA Password: dd73

After decompression, enter the opencv folder, and enter in sequence:

mkdir build # 创建编译的文件目录

cd build

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..

make -j8  #编译

3. Error reporting

Resolved:
Resolved Makefile:162:recipe for target 'all'

4、`sudo make install`

5. Use `pkg-config --modversion opencv`Check Version.

If 3.4.0 is displayed, the installation is successful.

6. Install caffe

Look directly at the ninth step of the Ubuntu16.04 Caffe installation step record (super detailed) .

Attach the Baidu network disk link of caffe: https://pan.baidu.com/s/136rSSq3tbZ3Kh-IbMHi7Hg Password: bwuq

Note: Errors after make all -j8:

（1）make: *** [.build_release/cuda/src/caffe/solvers/adadelta_solver.o] Error 1

insert image description here
Solution: https://blog.csdn.net/qq_18649781/article/details/89047437
Makefile.config is a read-only file and must be opened with the command line: sudo gedit Makefile.config.

Tip: Before re-make all -j8 each time, it needs to sudo make cleanbe done.

(2) fatal error: google/protobuf/port_def.inc: No such file or directory
insert image description here
Solution: refer to here and here

Install Google Logging Library (glog):
Download link: https://github.com/google/glog/releases
Attach Baidu network disk link of glog0.3.3: https://pan.baidu.com/s/1Ci8rhKlctrpQm8_ditBhUA Password: wr74
tar zxvf glog-0.3.3.tar.gz
cd glog-0.3.3
./configure
make
ERROR:
SOLUTION: Change glog-o.3.3/src/demangle.cc to

if (str == '\0')    改为：if (str == "\0")
if (state->mangled_cur == '\0' ) 改为：if (state->mangled_cur == "\0" )

Save and exit.

sudo make install
Then re-modified Makefile.config
and pasted Makefile.config

Recompile again. First in the caffe folder and sudo make cleansecondmake all -j8

(3) fatal error: pyconfig.h: there is no such file or directory
insert image description here to solve: fatal error: pyconfig.h: there is no such file or directory
It is best to use at last:make all -j8

7. Use `sudo make runtest -j8`and test it.

(1) Error 1:
insert image description here Solution: Refer to the solution of libcudart.so.8.0: cannot open shared object file: No such file or directory

Record my steps:

Check whether libcudart.so.10.0 exists in the /usr/local/cuda-10.0/lib64 directory, if it exists:
make clean
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.0/lib64
make all -j8
