Installation failed? ImportError: libopenpose.so.1.2.1: cannot open shared object file: No such file or directory

[joseph-zhong]

Hi, after installing OpenPose, Caffe with OpenCV3, and modifying my $PYTHONPATH, I get an import error related with OpenPose and not really sure how to resolve

~$ echo $PYTHONPATH
/usr/local/PyOpenPose/build/PyOpenPoseLib:......
$ echo $OPENPOSE_ROOT
/usr/local/openpose

~$ python -c 'import PyOpenPose'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: libopenpose.so.1.2.1: cannot open shared object file: No such file or directory

Knowing the location of libopenpose.so.1.2.1, I tried the following and got a different error...

$ cd $OPENPOSE_ROOT/build/src/openpose; ls libopenpose.so; python -c 'import PyOpenPose'
libopenpose.so
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: /usr/local/PyOpenPose/build/PyOpenPoseLib/PyOpenPose.so: undefined symbol: _ZN5boost6python7numeric5array19set_module_and_typeEPKcS4_

Any ideas on what's missing?
Thanks in advance!

Add the location of libopenpose to your LD_LIBRARY_PATH.
The library file must have the correct version on the name.

Hi @padeler thanks for the suggestion, I added it to the path, but I'm still getting the following error

~$ python -c 'import PyOpenPose'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: /usr/local/PyOpenPose/build/PyOpenPoseLib/PyOpenPose.so: undefined symbol: _ZN5boost6python7numeric5array19set_module_and_typeEPKcS4_

It looks like something is wrong with Boost? Is there a particular version that is needed?
Thanks

[padeler]

Is the boost_python lib in your LD_LIBRARY_PATH?
Use ldd on the PyOpenPose.so to see the versions of the libs needed.

[HongDouE]

你的 LD_LIBRARY_PATH 中有 boost_python 库吗？ 在 PyOpenPose.so 上使用 ldd 查看所需库的版本。

您好，我也是出现了相同的问题

$ python -c 'import pydbow2'
Traceback (most recent call last):
File "", line 1, in
ImportError: ./pydbow2.so: undefined symbol: ZN5boost6python7numeric5array19set_module_and_typeEPKcS4

我尝试用ldd查看库版本
