# NOTE [ Why skip dynamic graph check ]:
# 1. If the input type / dtype of a layer is wrong, it will be reported
# directly on that line. User can easily print the relevant information
# on which line. It is easier to debug, so there is no need to check
# in dynamic graph mode.
# 2. Performance considerations. Because these checks are executed at
# each step in dynamic graph mode, it will bring a heavy performance burden.
