Hi, I am trying to clone the openimage branch by using command:

git clone -b openimages2 --recursive https://github.com/mahyarnajibi/SNIPER.git

and I got a fatal error stating that I cannot read from SNIPER-mxnet remote module. The complete error message is as follow:

Problem is caused by using ssh address in .gitmodule file instead of https address. Would be solved with the address corrected.
