Input(Input) and Output(Output) are in NCDHW or NDHWC format. Where N is batch size C is the number of channels, D is the depth of the feature, H is the height of the feature, and W is the width of the feature. Convlution3D is similar with Convlution2D but adds one dimension(...

但更多的是,利用已经重载了__format__的基础数据类型,比如str,int,float等。 针对format_spec格式化,python遵循标准:Format Specification Mini-Language 基本规范就是: format_spec ::= [[fill]align][sign][#][0][width][grouping_option][.precision][type] ...
