python memoryerror解决办法-育师

解决可从以下几个方面入手：

寻求数据处理方式的优化: 借助特定所提及的参数, 以分批的形式去读取大型文件, 像是采用pd.'( '.csv', =1000)这种方式, 针对数据进行逐块处理, 也能够运用生成器也就是yield来逐行处理数据, 以此避免将全部内容一次性加载进内存之中。与此同时, 使用numpy数组去替换列表, 或者挑选Dask等分布式计算库来处理超大数据集。处于机器学习领域时, 还能够通过减小批量大小也就是这个括号内的数值来使内存使用得以下降。使得内存占用得以降低: 开展模型以及参数的优化工作, 像是运用轻量级模型（举例来说替代gpt2）；于其中借助torch.()将梯度计算予以禁用从而节省显存。适时地把无用变量予以删除（del）、调用gc.()手动促使垃圾回收, 又或者运用torch.cuda.()清理GPU内存。提高系统内存的能力, 要安装64位, 以此突破32位大约2GB的内存限制；在系统设置里调整虚拟内存也就是分页文件的大小, 步骤是控制面板, 然后是系统, 接着是高级系统设置, 再是性能,之后是高级, 随后是虚拟内存, 最后是自定义大小。检查内存泄漏, 需使用或定位内存占用异常的代码块, 修复未释放的资源, 像未关闭的文件句柄、循环引用对象。硬件以及环境进行优化时, 要将别的占用内存的程序关闭, 要么去升级物理内存也就是RAM；在虚拟机这个环境里直接对分配的内存大小作出调整。要是软件优化不够, 能够增添物理RAM或者使用内存容量更高的云服务器。

先借助分块处理、优化数据结构等代码层面的办法来优先予以解决, 要是没有效果, 那就对版本以及系统内存配置展开检查, 切实保证硬件资源是充足的。
