jupyter笔记本无法启动

Question

我已经在Win 10机器上安装了anaconda，但是jupyter笔记本电脑既没有从@Service class DelayingRequestSenderImpl(@Value("\${vk.request.interval}") private val interval: Int) : DelayingRequestSender { private var lastRequestTime: LocalDateTime = LocalDateTime.now() private val requestChannel: Channel<Deferred<*>> = Channel() //SupervisorJob is used because we want to have continuous processing of requestChannel //even if one of the requests fails private val coroutineScope = CoroutineScope(SupervisorJob()) override suspend fun <T> request(block: () -> T): T { val deferred = coroutineScope.async(start = CoroutineStart.LAZY) { block() } requestChannel.send(deferred) return deferred.await() } @PostConstruct fun startProcessing() = coroutineScope.launch { for (request in requestChannel) { val now = LocalDateTime.now() val diff = ChronoUnit.MILLIS.between(lastRequestTime, now) if (diff < interval) { delay(interval - diff) } lastRequestTime = LocalDateTime.now() request.start() } } } 到Anaconda Prompt也无法启动

当我执行Anaconda Navigator时，Anaconda Prompt中没有输出

和

当我在导航器中单击jupyter笔记本启动按钮时，它显示jupyter notebook，但此后什么也没发生

Answer 1

这个问题早已发生在我身上。不知道如何适当地解决该问题，但是那时我创建了一个新环境并在上面下载了jupyter笔记本。当然，值得研究的问题，但是我想您需要一个快速的解决方案。

这就是创建新环境的方式：

Answer 2

我终于修复了它，对我来说，解决方案是将Windows 10还原到以前的还原点并重新安装Anaconda，但这一次for all users
