GPU memory will not be released If the processing exits unexpectedly

[hjcenry]

For example,

1. I upload a photo, the face is not very clear, then the abnormal exit, but even if I change the correct photo, the previous GPU memory will not be released, and finally OOM
2. If my OOM module exits abnormally due to insufficient video memory, the GPU video memory will not be released. As a result, I directly use my OOM module for the next generation

Whether the author can solve this problem, I feel very serious, no exception processing
