我使用Tensorflow（CNN+RNN模型）在Keras中实现了一个模型。然而，当我想评估我的模型时，我有以下错误：

2018󈚰󈚪 09:48:44.961161: I tensorflow/core/platform     
/cpu_feature_guard.cc:140] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA

2018󈚰󈚪 09:49:00.450298: W tensorflow/core/framework/allocator.cc:101]    
Allocation of 3359939800 exceeds 10% of system memory.

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

这是一个CPU内存分配的问题，但我不知道如何解决这个问题。我的模型参数很小，所以我不认为这是问题。谢谢你的帮助。
