-Finally, set the database to multi-user mode.Shutter time: The smaller the shutter time, the faster the photo will be taken. However, due to the fast photo taking speed, the light may not be enough and the picture will appear very dark. 1, 2, 3 That means that the shutter time is 1 second, 2 seconds, 3 seconds, and the photographing time is getting slower and slower, which will make the light of the photo increase sharply, or even explode too much. In fact, long exposure means that the larger the shutter time, the better. It is suitable for photographing night scenes. Remember to use a tripod.The technical scheme further optimized by the utility model is that the valve seat 7 is made of polytrifluorochloroethylene.被大章鱼吞下去的杰克船长进入了戴维·琼斯控制的“死界”。为了拯救杰克，威尔、伊丽莎白和女巫等一行人也来到了“死界”。找到杰克，逃出了世界尽头。而此时狡猾的卡特勒已经得到了戴维·琼斯的心脏，由此挟持戴维·琼斯，掌控所有的公海海盗，为东印度公司攫取利益。为了应对危难，各地海盗头目秘密集会，展开是否释放女海神，杀掉戴维·琼斯的争论。在平静的海面上，风雨将至，最终的对决即将展开。Reporter: Everyone's reaction is what they think.Diao Shen Xia: This kind of person may not be limited to running a few demo. He has also made some adjustments to the parameters in the model. No matter whether the adjustment is good or not, he will try it first. Each one will try. If the learning rate is increased, the accuracy rate will decrease. Then he will reduce it. The parameter does not know what it means. Just change the value and measure the accuracy rate. This is the current situation of most junior in-depth learning engineers. Of course, it is not so bad. For Demo Xia, he has made a lot of progress, at least thinking. However, if you ask why the parameter you adjusted will have these effects on the accuracy of the model, and what effects the adjustment of the parameter will have on the results, you will not know again.山顶花丛中，奇香扑鼻，卓一航欣喜若狂，因为他看到了一株长有两朵蓓蕾的花，那两个蓓蕾一红一白，红的有如胭脂，白的宛如白玉，它们都如拇指般大，被花瓣紧紧包着。
