python - 尝试在Pycharm中运行程序

我必须在Pycharm中测试代码(问题的底部),但是我无法弄清楚如何在Pycharm中运行它而不会出现此错误:

usage: color.py [-h] -i IMAGE
color.py: error: the following arguments are required: -i/--image
我知道如果我使用Idle,我会编写以下代码:
/Users/syedrishad/Downloads/python-project-color-detection/color_detection.py -i 
Users/syedrishad/Downloads/python-project-color-detection/colorpic.jpg
但我不知道如何在Pycharm上运行它
我使用的是Mac,由于某种原因,我总是必须输入完整的路径名,否则它将不起作用(如果有所作为)
该程序可以使我双击图像的一部分,从而显示确切的颜色名称。所有颜色名称都存储在此文件中:
/Users/syedrishad/Downloads/python-project-color-detection/colors.csv
实际的代码在这里:
import cv2
import numpy as np
import pandas as pd
import argparse

#Creating argument parser to take image path from command line
ap = argparse.ArgumentParser()
ap.add_argument('-i', '--image', required=True, help="Image Path")
args = vars(ap.parse_args())
img_path = args['image']

#Reading the image with opencv
img = cv2.imread(img_path)

#declaring global variables (are used later on)
clicked = False
r = g = b = xpos = ypos = 0

#Reading csv file with pandas and giving names to each column
index=["color","color_name","hex","R","G","B"]
csv = pd.read_csv('colors.csv', names=index, header=None)

#function to calculate minimum distance from all colors and get the most matching color
def getColorName(R,G,B):
minimum = 10000
for i in range(len(csv)):
d = abs(R- int(csv.loc[i,"R"])) + abs(G- int(csv.loc[i,"G"]))+ abs(B- int(csv.loc[i,"B"]))
if(d<=minimum):
minimum = d
cname = csv.loc[i,"color_name"]
return cname

#function to get x,y coordinates of mouse double click
def draw_function(event, x,y,flags,param):
if event == cv2.EVENT_LBUTTONDBLCLK:
global b,g,r,xpos,ypos, clicked
clicked = True
xpos = x
ypos = y
b,g,r = img[y,x]
b = int(b)
g = int(g)
r = int(r)

cv2.namedWindow('image')
cv2.setMouseCallback('image',draw_function)

while(1):

cv2.imshow("image",img)
if (clicked):

#cv2.rectangle(image, startpoint, endpoint, color, thickness)-1 fills entire rectangle
cv2.rectangle(img,(20,20), (750,60), (b,g,r), -1)

#Creating text string to display( Color name and RGB values )
text = getColorName(r,g,b) + ' R='+ str(r) + ' G='+ str(g) + ' B='+ str(b)

#cv2.putText(img,text,start,font(0-7),fontScale,color,thickness,lineType )
cv2.putText(img, text,(50,50),2,0.8,(255,255,255),2,cv2.LINE_AA)

#For very light colours we will display text in black colour
if(r+g+b>=600):
cv2.putText(img, text,(50,50),2,0.8,(0,0,0),2,cv2.LINE_AA)

clicked=False

#Break the loop when user hits 'esc' key
if cv2.waitKey(20) & 0xFF ==27:
break

cv2.destroyAllWindows()
如果您知道如何运行,请告诉我。我一直在寻找答案,但空手而归。

最佳答案

正如@Yves Daoust提到的,您基本上有两种选择:
A)更改您正在测试的代码以提供所需的参数,或者
B)使用Run-> Run ...-> Edit Configurations ...来提供参数,就像在命令行中一样。
让我们更详细地检查您拥有的选项:
A)最简单的方法是像这样提供要打开的图像的路径:

# replace img_path = args['image'] with
img_path = 'path/to/the/image'
它具有非常容易获得的优点,但是却破坏了argparser的功能。
一种更通用的解决方案是提供一个默认参数,并在每次您要打开图像时对其进行编辑。
import argparse

# Add a global variable here. It will provide the argument if no other is given (via `Run->Run...->Edit Configurations...`)
IMAGE_PATH = 'path/to/image'
#Creating argument parser to take image path from command line
ap = argparse.ArgumentParser()
ap.add_argument('-i', '--image', required=True, help="Image Path", default=IMAGE_PATH)
如果您对此感兴趣,可以保持arg解析功能完好无损。
B)此选项意味着您可以像在控制台中一样自行提供参数。参数将放置在“参数:”字段中。
例如,您可以通过:
--image="path/to/image"
PyCharm提供了“应用”(按钮)您所插入的更改的选项(在这种情况下,这意味着只要脚本在内存中,就保留为此脚本存储的参数)。
希望这可以澄清一些事情。
