我正在使用GitHub的AlphaPose，我想从我在AlphaPose根中创建的另一个脚本run.py运行脚本script/demo_inference.py。在run.py中，我使用以下脚本将demo_inference.py导入为ap:
def import_module_by_path(path):
name = os.path.splitext(os.path.basename(path))[0] spec =
importlib.util.spec_from_file_location(name, path) mod =
importlib.util.module_from_spec(spec) spec.loader.exec_module(mod) return mod
和
ap = import_module_by_path('./scripts/demo_inference.py')
然后，在demo_inference.py中我替换了
if __name__ == "__main__":
def startAlphapose():
在run.py中我写了
ap.StartAlphapose().
现在我得到了这个错误:
Load SE Resnet...

这是什么意思?
我们的集群也遇到了同样的问题。
在PyTorch中使用multiprocessing(通常运行多个DataLoader worker)时，子进程在/tmp目录中创建套接字以相互通信。这些套接字都保存在名为pymp-######的文件夹中，看起来像0字节文件。在PyTorch脚本仍在运行时删除这些文件或文件夹将导致上述错误。
在我们的情况下，问题是一个错误的维护脚本，擦除文件的/tmp文件夹，而他们仍然需要。可能还有其他方法触发此错误。但是你应该从寻找这些套接字开始，并确保它们不会被意外擦除。
如果这不能解决问题，请在错误发生的确切时间查看您的/var/log/syslog文件。你很可能在那里找到它的原因。
