无法初始化服务器：无法连接：连接被拒绝

Question

我尝试使用Google合作实验室的出色GPU，让我通过YOLOV 3学习模型。

extension UIImage {

    static func swizzleInitImplementation() {
        let originalSelector =  #selector(UIImage.init(named:))
        let swizzledSelector = #selector(UIImage.ftg_imageNamed(named:))


        let imgSelf: AnyClass = self.classForCoder()

        guard  let originalMethod = class_getClassMethod(imgSelf, originalSelector),
            let swizzledMethod = class_getClassMethod(imgSelf, swizzledSelector) else {
                assertionFailure("The methodsw are not found")
                return
        }

        let imp1 = method_getImplementation(originalMethod)
        let imp2 = method_getImplementation(swizzledMethod)
        method_setImplementation(originalMethod, imp2)
        method_setImplementation(swizzledMethod, imp1)

    }

    @objc static func ftg_imageNamed(named name: String)  {
        setAccessibilityLabel(name)
        self.ftg_imageNamed(named: name)
    }

}

然后我遇到了这样的错误

% cd / content / darknet-master / build / darknet / x64
! ./ darknet detector train data / obj.data yolov3-obj.cfg 
darknet53.conv.74> train_log.txt 

无法初始化服务器：无法连接：连接被拒绝意味着连接已断开并且无法学习？

如果是，我该如何解决？

Answer 1

Colab在网络浏览器中运行，因此有no X server。您需要安排跳过在笔记本中使用X11的过程，或配置类似xvfb的内容，以便在运行代码的后端提供X服务器。
