前言

最近在复现一篇论文的代码时发现了一个致命问题,研究了一天,终于还是破解了。网上找了半天,一个类似的解决方案都没有,记录一下。

错误出现的代码位置:

self.feature_app_file = h5py.File(self.opt.input_app_feature, 'r', driver='core')

错误信息

Traceback (most recent call last):

反正这个bad heap free list错误是第一次见,也是第一次解决。

解决方案

其实很简单,就是把后面的 driver='core'删了,就可以了。

self.feature_app_file = h5py.File(self.opt.input_app_feature, 'r')

完结,撒花~
