在使用过cv2后plt报错图片类型

我在用pycharm进行编程时，发现我用cv2处理完的图片再用plt显示时会出现报错提示没有转化成实数，原本被在IDLE还是可以运行的，这个问题似乎别人的pycharm没有，但是我有这个问题，怎么办
报错：

Traceback (most recent call last):

    raise TypeError("Image data of dtype {} cannot be converted to "
TypeError: Image data of dtype object cannot be converted to float

代码：

    proces = cv2.rectangle(proces, (x, y), (x + w, y + h), (255, 0, 0), 3)
    #展示图片
    plt.imshow(proces)
    plt.show(block=False)
    # 图片展示三秒
    plt.pause(3)
    # 销毁当前窗口
    plt.close()

注意，Python版本过高也会因为不稳定出现这个报错，我之前就3.10，退回3.9.7就不报这个错误

读取图片应该使用matplotlib.image
