Reproduces the problem - code sample
Technically, this is NOT a bug
A useful tool
get_model_complexity_info()
is provided to measure the FLOPs, #params, etc.But currently, this function considers
input_shape
as a required positional argument.Reproduces the problem - command or script
Save above code to
main.py
and runReproduces the problem - error message
Additional information
To solve this problem, one should specify
input_shape=None
, as in this line. This is neither elegant nor necessary.This is not reasonable
The arg
input_shape
is used to construct an input tensor only ifinputs
isNone
. See this line.This function should expect the users provide only one of
input_shape
andinputs
.A PR to optimize this
