My environment: Ubuntu 18.04 tensorflow 2.1
when reproducing pointsift, follow the readme prompt, modify the locations of tensorflow and Lib in the. Sh file, compile the. Sh file, and report an error:
/usr/bin/LD: cannot find – ltensorflow_framework
collect2: error: ld returned 1 exit status

The reason is that the shell file is connected to the dynamic library In libtensorflow_framework.so, the dynamic library name of tensorflow 2.1 is libtensorflow_Frame.So.2, so the link is not available

Solution: create a connection symbol to make libtensorflow_Framework. So. 2 and libtensorflow_Framework.so points to the same

cd /usr/local/lib/python3.6/dist-packages/tensorflow_core //My files are in this directory, some are in the tensorflow directory, as long as they are in the same directory as .so.2
ln -s libtensorflow_framework.so.1 libtensorflow_framework.so
