Element Ui 中表格设置max-height滚动条失效

为了是表格动态自适应页面高度,所以给表格设置了max-height属性,但是纵向滚动条消失了解决方案:设置表格属性.el-table{display:flex;flex-direction:column;}但是又出现了表格头部渲染问题:解决方案:之前看到有人说将el-table__header-wrapper的overflow属性设置为visible,但是会出现横向滚动时表头无法滚动的问题。后面经过探索,直接为表头设置一个固定高度即可解决问题。.el-table__header-wrapper{height:100px;}最终效果:

only batches of spatial targets supported (3D tensors) but got targets of dimension

问题产生的原因是使用nn.CrossEntropyLoss()来计算损失的时候,target的维度超过4importtorchimporttorch.nnasnnlogit=torch.ones(size=(4,32,256,256))#b,c,h,wtarget=torch.ones(size=(4,1,256,256))criterion=nn.CrossEntropyLoss()loss=criterion(logit,target)如实target中的C不是1,则可以:importtorchimporttorch.nnasnnlogit=torch.ones(size=(4,32,25

opencv调用摄像头报错(-215:Assertion failed) size.width>0 && size.height>0 in function ‘cv::imshow‘

我使用OpenCV调用摄像头时报错:error:(-215:Assertionfailed)size.width>0&&size.height>0infunction'cv::imshow'问题分析如下:error提示断言失败了,因为读入图片的宽和高至少有一样不大于0。报错代码如下:importcv2cap=cv2.VideoCapture(0)whileTrue:success,img=cap.read()cv2.imshow("Image",img)cv2.waitKey(1)改进方案:importcv2cap=cv2.VideoCapture(0)cap.set(3,640)cap.se

performance - 戈朗 : Find two number index where the sum of these two numbers equals to target number

问题是:找到nums[index1]+nums[index2]==target两个数字的索引。这是我在golang中的尝试(索引从1开始):packagemainimport("fmt")varnums=[]int{0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,25182,25184,25186,25188,25190,25192,25194,25196}//Thenumberlististoolong,Iputthewholenumbersinagist:https://gist.github.com/nickleeh/8eedb39e0

keil错误和解决办法(1):FCARM - Output Name not specified, please check ‘Options for Target - Utilities‘

keil错误和解决办法(1):FCARM-OutputNamenotspecified,pleasecheck‘OptionsforTarget-Utilities’这个错误是由于新导入到工程内的文件,未被正确识别而引发的错误报错:FCARM-OutputNamenotspecified,pleasecheck‘OptionsforTarget-Utilities’原因:用户的.c和.h文件往往都是新建txt,然后改的后缀,这样的文件被导入keil后,有可能会被识别成imagefile。在新导入到keil中的文件中找到图标和和其它文件不一样的,同样是.c文件,my_printf.c和其它.c文

微信小程序高度height设置百分比无效,只需一步搞定

  顶部  内容自适应  底部错误分析:设置父元素.father高度为100%无效,子元素高度设置百分比也无效,简易代码如下------  .father{    height:100%  }  .son1{height:20%}.son2{height:60%}.son3{height:20%}解决方案:直接加一个page{height:100%}即可,page是整个页面的父元素,相当于html内的body,适用于所有小程序里的页面
