问题 I have some simple if... elif... in my python3.6 (& OpenCV 4.0), but no matter what I do I keep getting strange error messages. I need to crop some pics according to some bounding boxes. # the image to be cropped loads here: tobecropped= cv2.imread(img) images.append(tobecropped) (imageheight, imagewidth) = tobecropped.shape[:2] # sample bounding box: y = 833 # center vertically x = 183 # center horizontally width = 172 height = 103 # calculation of cropping values adding 10% extra: y1 = y-

问题 Language: VBA - MS Access I am using User-Defined-Types (UDT) within my code. I would like to be able determine which section of the UDT i'm loading data into based on a state variable. My first attempt was to use "With" statements nested into an "IF" statement. This doesn't work (I get a compiler error that says Else without if). Is there a way to make this work? or another way of going about using a state variable to determine which section of the UDT i'm loading? Type MyOtherType Name as

问题 Suppose I have got a shorthand if-else statement inside a loop as in this case : for(...) { a = b == c ? b : c; // More unnecessary code if the result was true. } And I would like to break the loop by the result of the condition: for(...) { a = b == c ? b break : c; // Now the unnecessary code is not executed. } I realize I could just type it in a full way as in this example: for(...) { if( b == c ) { a = b; break; } else { a = c; } // Now the unnecessary code is not executed. } But it is too

问题 I'm trying to implement something like if np.max(subgrid) == np.min(subgrid): middle_middle = cur_subgrid + 1 else: middle_middle = cur_subgrid Since the condition can only be determined at run-time, I'm using Keras syntax as following middle_middle = K.switch(K.max(subgrid) == K.min(subgrid), lambda: tf.add(cur_subgrid,1), lambda: cur_subgrid) But I'm getting this error: <ipython-input-112-0504ce070e71> in col_loop(j, gray_map, mask_A) 56 57 ---> 58 middle_middle = K.switch(K.max(subgrid) ==
