git submodule update --init --recursive

Recently, when running several models, video detection, object detection, and building mxnet, there is a problem, record it.

For video detection, mxnet needs to use the specified version. After git switches to the specified version, it is updated, but it still prompts that some libraries cannot be found. After thinking about it, recursive should be useless, but when I cloned the project, it was obviously recursive. Later, I realized that the library under the master is different from the library under the submodule. You need to update --recursive under submodule. Take refuge in the network.
