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：
代码语言：javascript复制self.feature_app_file = h5py.File(self.opt.input_app_feature, 'r', driver='core')错误信息
代码语言：javascript复制Traceback (most recent call last):

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~
