运行训练2个模型后，keras退出代码-1073741819 (0xC0000005)

Question

我使用Pycharm来运行我的脚本。我有一个循环的脚本。每个循环: 1.选择一个数据集。2.训练一个新的Keras模型。3.评估该模型。

因此，代码可以完美运行2周，但当安装新的anaconda环境时，代码在该循环的两次迭代后突然失败。

Siamese神经网络的两个模型将训练得非常好，就在第三个循环之前，它崩溃了，进程结束，退出代码为-1073741819 (0xC0000005)。

奇怪的是，代码过去工作得非常好，即使我没有使用anaconda环境，而是使用了以前使用的环境，它仍然以相同的退出代码退出。

当我使用另一种类型的模型(密集神经网络)时，它也会崩溃，但在4次迭代之后。是否与内存不足有关？这是一个循环的例子。确切的模型无关紧要，它总是在列车模型线(点2和点3之间)经过一定数量的循环后崩溃。

以及密集神经网络的退出代码。
