shape

问题 I am trying to implement a Multivariate regression in tensorflow where I have 192 examples with 6 features and one output variable. From my model I get a matrix (192, 6) while it should be (192, 1). Does anybody know what is wrong with my code? I provided my code below. # Parameters learning_rate = 0.0001 training_epochs = 50 display_step = 5 train_X = Data_ABX3[0:192, 0:6] train_Y = Data_ABX3[0:192, [24]] # placeholders for a tensor that will be always fed. X = tf.placeholder('float', shape

问题 I currently have a program in Visio that when a specific shape in my custom stencil is dragged onto the screen, a user form comes up and asks the user a question with a combo box used for the user to select an answer. Based on the answer selected, the shape data should change for that object. The problem that I am facing is that I am not sure how to target the ID of the shape automatically to then change its shape data. Since multiple of these shapes may be placed, I can not manually write a

问题 I've many times done the following: <defs> <filter id="screen"> <feBlend mode="screen" in2="BackgroundImage"/> </filter> </defs> But when I, inside a shape, write "filter="url(#screen)", my shape disappears. I've tried it in every browser (Safari, Chrome, Firefox, FfxNightly). What am I doing wrong? It would help if someone could give me an example that they know works Thanks 回答1: You should try Opera and see the difference. It seems, Opera is the only browser that currently implements this

问题 The documentation of boolean_mask says that the shape of the mask must be known statically. But if you do mask.set_shape([None]) tf.boolean_mask(tensor, mask) it seems to work fine. Is there any reason to not do this? 回答1: Looking at the documentation closely reveals that it concerns the dimensionality of the mask, not its whole shape: mask : K-D boolean tensor, K <= N and K must be known statically. Your mask now has size None , meaning its static shape is completely unknown, including the

问题 How to draw the spring like shape using c# drawing class alt text http://img812.imageshack.us/img812/373/spring.jpg 回答1: This is more of a math problem than a C# one. What you want is to derive a Parametric equation for the curve you wish to draw. With that go and fill an array of Point objects with values for the parametric equation on a certain interval with a certain step (the smaller the step the more the final drawing will look like the actual shape). Then you can use g.DrawLines (MSDN:

问题 I'm developing an application in swift 3.0 with the Google Maps SDK. I have to say this is the first time I work with this SDK and it is so I need a little help. I think what I ask you will be easy for you. What I want to do is when the user enters a map editing mode (like this page http://www.birdtheme.org/useful/v3tool.html ). He can do two things: First he could draw polygons on the map (to mark the boundaries of a farmer field). I want the user to press a point on the map and generate a

问题 I use iTerm2 (Build 1.0.0.20130319) and Vim (bin of MacVim Snapshot 66) on top of OS X 10.7.5 as my CLI editing team. In iTerm2 I defined to use a non-blinking vertical bar as a cursor shape. In Vim I defined " Enter insert mode (Cursor shape: vertical bar) let &t_SI = "\<Esc>]50;CursorShape=1\x7" " Leave insert mode (Cursor shape: block) let &t_EI = "\<Esc>]50;CursorShape=0\x7" to be able to distinct between insert and normal mode. Basically this works fine. The problem arises when I leave

问题 I'm using JAVA. Ellipse2D s1=new Ellipse2D.Float(0,0,100,100); System.out.println(s1.intersects(99, 30, 100, 100)); Should return false but it return true. How to find intersection between 2 ellipse? Thx 回答1: CADEMIA has an useful api which can be downloaded from here. The class cib.util.geo.Geo2D has a method Geo2D#intersection which calculates the intersection points between two ellipses. Hope this will help you. Thanks. 来源： https://stackoverflow.com/questions/6544441/how-ellipse-to-ellipse

问题 How do I convert a Shape object like Rectangle2D.Double to an Image object? This way I can use a Shape object for a mousecursor replacement. 回答1: Do draw(shape) in a BufferedImage , as shown here. 回答2: You'll have to create an image object which contains the right pixels at the right locations. One way would be something like this: public Image makeImage(Shape s) { Rectangle r = s.getBounds(); Image image = new BufferedImage(r.width, r.height, BufferedImage.TYPE_BYTE_BINARY); Graphics2D gr =
