tensorflow - GPU上的Tensorflow OOM

Question

我正在Tensorflow的LSTM-RNN上训练一些音乐数据，并且遇到了我不明白的一些GPU内存分配问题:当实际上似乎还有足够的VRAM可用时，我遇到了OOM。
一些背景:
我正在使用6GB的GTX1060，Intel Xeon E3-1231V3和8GB的RAM开发Ubuntu Gnome 16.04。
因此，现在首先我可以理解的错误消息部分，然后我将再次向所有可能会要求它帮助的人添加整个错误消息:

I tensorflow/core/common_runtime/bfc_allocator.cc:696] 8 Chunks of size 256 totalling 2.0KiB I tensorflow/core/common_runtime/bfc_allocator.cc:696] 1 Chunks of size 1280 totalling 1.2KiB I tensorflow/core/common_runtime/bfc_allocator.cc:696] 5 Chunks of size 44288 totalling 216.2KiB I tensorflow/core/common_runtime/bfc_allocator.cc:696] 5 Chunks of size 56064 totalling 273.8KiB I tensorflow/core/common_runtime/bfc_allocator.cc:696] 4 Chunks of size 154350080 totalling 588.80MiB I tensorflow/core/common_runtime/bfc_allocator.cc:696] 3 Chunks of size 813400064 totalling 2.27GiB I tensorflow/core/common_runtime/bfc_allocator.cc:696] 1 Chunks of size 1612612352 totalling 1.50GiB I tensorflow/core/common_runtime/bfc_allocator.cc:700] Sum Total of in-use chunks: 4.35GiB I tensorflow/core/common_runtime/bfc_allocator.cc:702] Stats:

W tensorflow/core/common_runtime/bfc_allocator.cc:274] *********************___________*__***************************************************xxxxxxxxxxxxxx W tensorflow/core/common_runtime/bfc_allocator.cc:275] Ran out of memory trying to allocate 775.72MiB. See logs for memory state. W tensorflow/core/framework/op_kernel.cc:993] Resource exhausted: OOM when allocating tensor with shape[14525,14000]

因此，我可以读取到最多分配5484118016个字节，
已准备好使用4670717952字节，并分配另外777.72MB = 775720000字节。根据我的计算器，5484118016字节-4670717952字节-775720000字节= 37680064字节
因此，在为他要插入的新Tensor分配空间之后，仍然应该有37MB的可用VRAM。对我来说，这似乎也很合法，因为Tensorflow可能不会(尝试)分配比可用内存更多的VRAM，而只是将其余数据保留在RAM或其他内容中。

现在我想我的思维中只有一个大错误，但是如果有人可以向我解释这个错误是什么，我将不胜感激。解决我的问题的明显策略是使我的批处理变得更小，使每个处理约1.5GB，这可能太大了。我还是很想知道实际的问题是什么。

编辑:我发现告诉我尝试:

config = tf.ConfigProto()
config.gpu_options.allocator_type = 'BFC'
with tf.Session(config = config) as s:

这仍然不起作用，但是由于tensorflow文档缺乏任何解释

 gpu_options.allocator_type = 'BFC'

会的，我很想问你们。

向有兴趣的人添加其余错误消息:

很抱歉复制/粘贴的内容过长，但也许有人需要/想要查看它，

提前谢谢你
里昂
