报错：ValueError: At least one stride in the given numpy array is negative, and tensors with negative s

数据导入时报如上错误，错误代码如下

return {'imidx':torch.from_numpy(imidx), 'image': torch.from_numpy(tmpImg), 'label': torch.from_numpy(tmpLbl)}

解决方案
在修改torch.from_numpy(imidx)中的imidx为np.ascontiguousarray(imidx)；tmpImg与tmpLbl使用相同的方式修改，修改结果如下：

return {'imidx':torch.from_numpy(np.ascontiguousarray(imidx)), 'image': torch.from_numpy(np.ascontiguousarray(tmpImg)), 'label': torch.from_numpy(np.ascontiguousarray(tmpLbl))}
