PyTorch错误收集与解决方法

不定时更新，主要收集自己使用pytorch过程中遇到的错误。

RNN的初始状态在多GPU训练报错

init_state = torch.zeros(2,200,32) # 这个我是使用register_buffer注册到模型中了
self.rnn(x,init_state)
>>>但gpu这样做事没问题的，但是多gpu会出现问题
init_state  = torch.zeros(4,100,32) #相当于 2*2,200/2 ,32
self.rnn(x,init_state)

RuntimeError: module must have its parameters and buffers on device cuda:0 (device_ids[0]) but found one of them on device: cpu

解决方法就是让，parameters(模块)或者buffers .to('cuda') 就可以了

RNN module weights are not part of single contiguous chunk of memory

每次要调用了一下flatten_parameters()

def forward(self,x):
    self.gru.flatten_parameters()
    output,hidden = self.gru(x)

问题出在embedding上的数量上，初始化是Embedding(400000,50),结果输入数据中居然包含有400001,就导致embedding出现错误。
