在你的代码中,imshow函数的第一个参数是窗口的名称,第二个参数是要显示的图像。你需要确保你传递了正确的图像路径和图像文件名,同时你需要确保该文件存在并且可以被打开。此外,你还需要适当地安装和配置opencv库,以确保它可以正确地运行。你可以尝试以下代码来检查是否正确安装了opencv库:
```
import cv2
print(cv2.__version__)
```
如果你的opencv库没有正确安装,那么你需要重新安装它。如果你的opencv库已经正确安装,那么你需要确保你的代码和图像文件都位于同一目录下。如果你还是遇到问题,请提供更多的代码和错误信息,我可以帮助你更好地解决问题。

`import cv2`是Python中OpenCV库的导入语句,用于图像处理和计算机视觉任务。`import matplotlib.pyplot as plt`是Python中Matplotlib库的导入语句,用于绘制图表和可视化数据。`%matplotlib inline`是Jupyter Notebook中的魔法命令,用于在Notebook中显示Matplotlib绘制的图表。`img = cv2.imread("C:\\Users\\86135\\Desktop\\pj\\c.jpg")`是使用OpenCV库中的imread()函数读取指定路径下的图像文件,并将其存储在变量img中。如果读取成功,img将是一个NumPy数组,可以对其进行进一步的处理和操作。

Sorry, as an AI language model, I am not able to display images or execute code. However, here is an example of how to read an image in OpenCV and display it using Matplotlib:
```
import cv2
import matplotlib.pyplot as plt
# read image
img = cv2.imread('image.jpg')
# convert color space
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
# display image
plt.imshow(img)
plt.show()
```
Keep in mind that you need to have the necessary libraries installed and the image file in the same directory as your Python script.
