请求支持F.conv_transpose2d

[Baiyuetribe]

model | 模型 | モデル

主要出现在stylegan、gpen、dragGAN等

how to reproduce | 复现步骤 | 再現方法

现有pnnx直接转换会出现如下ignore

ignore F.conv_transpose2d F.conv_transposend_45 param bias=None
ignore F.conv_transpose2d F.conv_transposend_45 param dilation=(1,1)
ignore F.conv_transpose2d F.conv_transposend_45 param groups=1
ignore F.conv_transpose2d F.conv_transposend_45 param output_padding=(0,0)
ignore F.conv_transpose2d F.conv_transposend_45 param padding=(0,0)
ignore F.conv_transpose2d F.conv_transposend_45 param stride=(2,2)
