yolov5-6 The “freeze_support()“ line can be omitted if the program is not going to be frozen

在yolov5-6 中单独创建文件计算anchor 时报错

import utils.autoanchor as autoAC# 对数据集重新计算 anchors
new_anchors = autoAC.kmean_anchors('data/test.yaml', 3, 320, 4.0, 1000, True)
print(new_anchors)

报错：

File "D:\Anaconda3\envs\yolo\lib\multiprocessing\spawn.py", line 134, in _check_not_importing_mainraise RuntimeError('''
RuntimeError: An attempt has been made to start a new process before thecurrent process has finished its bootstrapping phase.This probably means that you are not using fork to start yourchild processes and you have forgotten to use the proper idiomin the main module:if __name__ == '__main__':freeze_support()...The "freeze_support()" line can be omitted if the programis not going to be frozen to produce an executable.

原因是没有吧要运行的函数放到main 函数中执行

把你要运行的代码块放到main函数中运行 ok

import utils.autoanchor as autoAC
if __name__ == '__main__':# 对数据集重新计算 anchorsnew_anchors = autoAC.kmean_anchors('data/test.yaml', 3, 320, 4.0, 1000, True)print(new_anchors)
