ModuleNotFoundError：没有名为darkflow.cli和'nms'的模块

Question

我正在https://github.com/llSourcell/YOLO_Object_Detection尝试YOLO教程

当我执行此步骤时：

flow --h

我收到此错误：

File "/anaconda2/bin/flow", line 4, in <module>

    from darkflow.cli import cliHandler

ImportError: No module named darkflow.cli

我试图到处寻找解决方案，但没有运气。然后我尝试跳过该行并继续...

flow --model cfg/yolo-new.cfg --load bin/yolo-tiny.weights --train --gpu 1.0

我收到此错误：

Traceback (most recent call last):
