Can I use my Fermi GPU with compute capability 2.1 to run caffe_unet?

In principle yes, but the pre-built binaries require at least compute capability 3. You can build from source, though. When using Ubuntu 16.04 it works out-of-the box with g++ 5.4, CUDA 8.0.61 and corresponding cuDNN. Things changed with Ubuntu 18.04, because the dependent google libraries now require c++11 features. You can enable them by adding the line

 set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

to CMakeLists.txt but, think about a more recent GPU, a GTX1080 is quite cheap!
