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 I am trying to create a jigsaw puzzle and I need to mask the UIImages to obtain the puzzle pieces. I don't understand how can I mask a JPG picture because as I understand it doesn't have an alpha channel. Can anyone help me with this? The JPGs are on an online server and there is no way to download them as PNG. And one more thing, I can’t find this function anywhere on the Apple documentation: “CopyImageAndAddAlphaChannel”. Does it even exist. I found a few references on some forums but

问题 Using NSBezierPath addClip only limits drawing to inside the path used for clipping. I'd like to do the opposite - Only draw outside. - (void)drawRect:(NSRect)dirtyRect { NSBezierPath *dontDrawInThis = ...; //We want an opposite mask of [dontDrawInThis setClip]; //Drawing comes here } 回答1: This was my solution: - (void)drawRect:(NSRect)dirtyRect { NSBezierPath *dontDrawInThis = ...; // The mask is the whole bounds rect, subtracted dontDrawInThis NSBezierPath *clip = [NSBezierPath

问题 I have an 3D array that is a mask. Additionally, I have some indices that encode where (array position) some values should be saved. Everything seems to be working fine, except that the output matrix is still empty after assigning the values to the desired positions. I can not see what I am missing here. I have also tried numpy.put with no luck. import numpy as np # Initialize output matrix (here the results will be stored) results = np.zeros((67, 67, 45)) # define the mask - where to put the

问题 I was just wondering if someone could help show me how to apply functions such as "sum" or "mean" on masks arrays using dask. I wish to calculate the sum / mean of the array on only values where there is no mask. Code: import dask.array as da import numpy as np import numpy.ma as ma dset = [1, 2, 3, 4] masked = ma.masked_equal(dset, (4)) # lets say 4 should be masked print(np.sum(masked)) # output: 6 print(np.mean(masked)) # output: 2 print(masked) # output: [1, 2, 3, -] masked_array = da

问题 I have an input in my form that takes a credit card number. <input type="text" class="form-control" name="CCnumber" ng-model="CCnumber" ng-blur="balanceParent.maskCreditCard(this)"> On blur, I'd like to mask the credit card input like so: 4444************ And then on focus, I'd like to return the original credit card number: 4444333322221111 Using ng-blur, I'm able to do simple javascript to return a masked input. vm.maskCreditCard = function(modalScope) { if(modalScope.CCnumber){ var

问题 My web site has navigation, presented as a list of rectengular buttons with round corners . Each button should have it's own custom background, which is a photo. Photo is bigger than button and should move in response to mouse movement over this button. We have an effect, like we are looking through the window. Navigation has following HTML structure: "ul > li > a > img". I think, each "ul > li" should be a rectangle with round corner and acting as clipping mask for image. Setting "overflow:
