无法将绘图发送到http://127.0.0.1:63342

Question

我遇到一个错误，即使用 python、numpy 和 matplotlob 将绘图发送到特定 IP 地址。我附上了我到目前为止已经尝试过的片段。

Python

     import numpy as np
     import cv2
     from matplotlib import pyplot as plt
     img = cv2.imread('ml.png', 1)
     gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)



    img2 = cv2.imshow('img', img)
    cv2.waitKey(0)
    corners = cv2.goodFeaturesToTrack(gray, 30, 0.01, 10)
     corners = np.int0(corners)

    for i in corners:
    x, y = i.ravel()
    cv2.circle(img, (x, y), 10, 50, 0)
    plt.imshow(img), plt.show()
    MIN_MATCHES = 15
    cap = cv2.imread('mario.png', 0)
     model = cv2.imread('mario 3d.jpg', 0)

    # create brute force  matcher object
    bf = cv2.BFMatcher(cv2.NORM_HAMMING, crossCheck=True)
    # Compute model keypoints and its descriptors
    kp_model = cv2.goodFeaturesToTrack(model, 20, 0.01, 15)
    des_model = cv2.goodFeaturesToTrack(model, 20, 0.01, 15)
    # Compute scene keypoints and its descriptors
    kp_frame = cv2.goodFeaturesToTrack(cap, 20, 0.01, 15)
    des_frame = cv2.goodFeaturesToTrack(cap, 20, 0.01, 15)
    # Match frame descriptors with model descriptors
    matches = bf.match(des_model, des_frame)
    # Sort them in the order of their distance
    matches = sorted(matches, key=lambda x: x.distance)

    if len(matches) > MIN_MATCHES:
        # draw first 15 matches.
        cap = cv2.drawMatches(model, kp_model, cap, kp_frame,
                              matches[:MIN_MATCHES], 0, flags=2)
        # show result
        cv2.imshow('frame', cap)
        cv2.waitKey(0)
    else:
        print

错误：

Answer 1

尝试在 PyCharm 中显示 matplotlib 绘图时，我还收到“错误：无法将绘图发送到 http://127.0.0.1:63342”错误消息。我通过禁用“设置”>“工具”>“Python Scientific”下的“在工具窗口中显示绘图”选项来修复此问题。如果错误消息仍然存在，请尝试在 PyCharm 之外重现错误

Answer 2

我发现当我在 Pycharm 的绘图窗口中堆积了太多运行时，就会出现这个问题。换句话说，就是“满”了。清除旧的绘图后，它可以再次将绘图发送到窗口。不必禁用它。重新启动我的计算机也有效，但这可能是因为它也清除了窗口。 :-) 希望这有帮助！

Answer 3

取消选中“在工具窗口中显示绘图” 设置>>工具>>Python科学>>

Answer 4

对我有用的另一件事是将 localhost 添加到 no_proxy 环境变量中。请务必添加端口

export no_proxy=$no_proxy,127.0.0.1:63342

Answer 5

以上所有解决方案都不适合我。简单的 PyCharm restart 即可解决该问题。

非常愚蠢，但可能会被忽视。只是发帖以防有帮助。

Answer 6

就我而言，这是因为我的VPN V2rayU启用了全局代理模式。一旦禁用它，错误就消失了。
