Hello, there is another possibility: If the output contain some large values (abs (value) > 1e20), then nn.LayerNorm (output) might return a all nan vector. Similiar problem happens in my attention model, I’m pretty sure that it can’t be exploding gradients in my model ...

PyTorch的nn.Linear（）是用于设置网络中的全连接层的，需要注意的是全连接层的输入与输出都是二维张量，一般形状为[batch_size, size]，不同于卷积层要求输入输出是四维张量。其用法与形参说明如下： in_features指的是输入的二维张量的大小，即输入的[batch_size, size]中的size。
