我尝试加载大型音频数据集并实现audio.spectrogram. 我收到了这个错误： $Torch: not enough memory: you tried to allocate 0GB. Buy new RAM! at /home/XXXX/torch/pkg/torch/lib/TH/THGeneral.c:222stack traceback:[C]: at 0xb73

torch7有内存限制吗？
不,Torch没有内存限制,但它需要在分配内存时满足某些条件.如果你看一下THGeneral.c(错误的来源),你会发现当使用THAllocInternal的分配失败时会引发这个错误.从你的输出我猜你是在Unix系统上我也猜你正在尝试分配大量的内存(但不到1GB).如果要对齐超过5120个字节,THAllocInternal将调用posix_memalign作为64字节对齐的内存,否则它将调用标准malloc.也就是说,您看到的错误来自您的操作提供的任何一个函数系统.你必须在那里检查.你也可以尝试用标志DISABLE_POSIX_MEMALIGN重新编译Torch来排除它.
