电脑扩展投屏
1、在今年过年期间,我曾经接到一个电话,是咨询怎么将电脑投屏到电视机而又不影响电脑正常办公的。当下电脑投屏到大屏幕有两种模式:一种就是镜像模式和扩展模式。面对该网友的咨询,我直接告诉用户,用电脑扩展投屏模式就可以了。
2、AWIND奇机无线投屏器会议级别的都支持扩展投屏,我们将HDMI线与电视机连接,将USB小电子插在电脑的USB接口上,启动投屏,在投屏功能选择【扩展投屏】即可。(PS:默认的是镜像投屏,我们只需要将选项更改下就好了)。
2060 算力
1、实测使用联想Y720,GTX1060,跑tensorflow。环境是vs2017,配置有点麻烦,但是确定可以成功,安装好gpu版的tf之后,需要安装cuda和cudnn,其中涉及到版本,需要有一各cudnn的高低版本混装的过程。测试时间2017年12月。最近(2018年2月),听说英伟达有更新,可能安装会更容易,默认全性能运行cuda(好像是)。
2、理论上是可以的。虽然没试过GTX1660TI,但是GTX1060是没有问题的,新款显卡没有理由不支持,如果楼主测试,加速环境显示不支持,可以更换别的编译器版本,也可以参考网上的深度学习环境搭建参考一下。
3、当然支持。之前持续跑了一个星期tensorflow,任务管理器可以看到Cuda占有率100%,电费都多了20块钱。tensorflow显示GTX 1660的计算能力为5。应该没这么高,估计1。使用其GPU计算1000万的矩阵乘法,速度大概是CPU( i59代) 的200倍。

1、在与主持人社区测试了多个版本的钱包之后,核心团队在今天早约12个小时的时间内将Pi Wallet测试版发布到任何活动的Node上,并招募了10,000多位Pioneers通过Node UI进一步测试了钱包。在此测试版本的新注册结束后,在过去的开放注册期内创建钱包的节点将继续查看,测试钱包,进行Test-Pi交易并提供反馈。从测试版本中获得的经验将帮助我们改善钱包的功能,可伸缩性和UI / UX,以进行更大的发布。
2、We had a test release of the Pi Wallet to any active Node during the past 12 hours and enrolled over 10,000 Pioneers to test the wallet through Node UI. The learnings from the test release will help us improve the wallet’s functionalities, scalability and UI/UX for a larger launch. Pi Wallet will be connected to Pi Testnet and initiated with Test-Pi by the Testnet faucet. Test-Pi is NOT REAL and has NO VALUE. More details about the Pi Wallet will come around Pi Day!
3、The Pi Wallet will be connected to Pi Testnet and initiated with Test-Pi by the Pi Testnet faucet, which is a facility on the Testnet to distribute free test-Pi. Test-Pi (or test-π) is NOT REAL Pi! Test-Pi is solely for the purpose of testing transactions on the Pi Testnet and contains NO VALUE. The Test-Pi balance in the wallet may be reset because Testnet will be periodically reset as part of the testing. Please remember that currently sales of Pi are unauthorized and violate the terms of service, which may result in freezing the account. Please report violators.
4、Pi钱包将连接到Pi Testnet,并通过Pi Testnet龙头与Test-Pi一起启动,该龙头是Testnet上用于分发免费test-Pi的设施。 Test-Pi(或test-π)不是真实的Pi! Test-Pi仅用于在Pi Testnet上测试交易的目的,并且不包含任何值。可以重置钱包中的Test-Pi余额,因为Testnet将作为测试的一部分定期重置。请记住,Pi的当前销售是未经授权的,并且违反了服务条款,这可能会导致帐户冻结。请举报违规者。
