迁移学习调用预训练模型出现Given input size: (512x3x3). Calculated output size: (512x-3x-3)错误

    调用预训练模型ResNet18时报错：RuntimeError: Given input size: (512x3x3). Calculated output size: (512x-3x-3). 
Output size is too small at /opt/conda/conda-bld/pytorch_1535491974311/work/aten/src/THCUNN/generic/
SpatialAveragePooling.cu:63

其解决方法是将倒数第二层的self.avgpool = nn.AdaptiveAvgPool2d((1, 1))替换为
self.avgpool = nn.AdaptiveAvgPool2d(1)即可。具体原因可能是一个bug.
