解决[W pthreadpool-cpp.cc:90] Warning: Leaking Caffe2 thread-pool after fork. (function pthreadpool）
pytorch 1.9遇到如下问题
问题：
[W pthreadpool-cpp.cc:90] Warning: Leaking Caffe2 thread-pool after fork. (function pthreadpool)
[W pthreadpool-cpp.cc:90] Warning: Leaking Caffe2 thread-pool after fork. (function pthreadpool)
[W pthreadpool-cpp.cc:90] Warning: Leaking Caffe2 thread-pool after fork. (function pthreadpool)
[W pthreadpool-cpp.cc:90] Warning: Leaking Caffe2 thread-pool after fork. (function pthreadpool)
解决方法：
DataLoader函数中参数改成pin_memory = False
改前：
DataLoader(val_dataset, shuffle=True, batch_size=Batch_size, num_workers=4, pin_memory=True,drop_last=True, collate_fn=yolo_dataset_collate)
改后：
DataLoader(val_dataset, shuffle=True, batch_size=Batch_size, num_workers=4, pin_memory=False,drop_last=True, collate_fn=yolo_dataset_collate)
