例如,我定义了一个模型,如下所示:
class Net(nn.module):
def __init__():
self.conv11 = nn.Conv2d(in_channel,out1_channel,3)
self.conv12 = nn.Conv2d(...)
self.conv13 = nn.Conv2d(...)
self.conv14 = nn.Conv2d(...)
...
#Here is the point
flat = nn.Flatten()
#I don't want to compute the size of data after flatten, but I need a linear layer.
fc_out = nn.Linear(???,out_dim)

问题是线性层,我不想计算线性层输入的大小,但定义模型需要指定它。我怎么解决这个问题?
如果您不想显式计算输入大小,您可以使用一个LazyLinear模块(而不是 a Linear)来推断它:
fc_out = nn.LazyLinear(out_dim)
