I succesfully builded Caffe on Windows 10 by following https://github.com/BVLC/caffe/tree/windows.
Then, after copying C:\Projects\caffe\python\caffe folder to my Python site_packages folder, I can use "import caffe" in Python.
My question is that if I want to use Caffe on other computers without building Caffe from the beginning, do I just need to copy the files in C:\Projects\caffe\python\caffe folder to the other computers' site_packages folder?
Actually, I am not familiar with 'build' and 'compile' and I don't know what 'build' is doing during the Caffe installation.
You can do the copy provided that the destination computer uses the same support libraries (for software linkage to your Python and Caffe) and has bit-compatible hardware (to support the binary code).
I do this regularly, within a controlled cluster. All the nodes have the same OS configuration. I build on one node, and then copy the entire directory to the same place on the other nodes. Then I run multi-node applications on the result.
If you switch to a different core processor, or a different OS implementation, your attempts to use the result will likely crash. I've tried that one, too. :-)
