Add dilations for conv2d and optimize conv2d code by chengduoZH · Pull Request #5472 · PaddlePaddle/Paddle

chengduoZH · 2017-11-08T06:18:01Z

Add dilations for im2col(ColFormat::kCFO).
Fix conv2d doc (Add dilation)
Refine conv2d_op unit test.(Add dilation)
Refine conv_op for filter size:(1,1), (when filter_size, paddings, strides, dilations are (1,1), (0, 0), (1,1), (1,1), conv_op just likes fc_op)
Add dilations for vol2col(ColFormat::kCFO).
Fix conv3d doc (Add dilation)
Refine conv3d_op unit test.(Add dilation)

paddle/operators/conv_op.h

+    filter_1 &= (static_cast<int>(filter_dim[j]) == 1);
+    strides_1 &= (strides[j] == 1);
+    padding_0 &= (paddings[j] == 0);
+    dilation_1 &= (dilations[j] == 1);


&= -> &&= ?

没有这种表示&&=，我改成了strides_1 = strides_1 && (strides[j] == 1)

paddle/operators/conv_op.h

-          vol2col(context.device_context(), in_slice, col, strides[0],
-                  strides[1], strides[2], paddings[0], paddings[1],
-                  paddings[2]);
+    if (!not_expand) {


! not expand = expand, the logic is a little complex,

How about rename NotExpand to IsExpand? Then return True, means that it needs to expand, ortherwise, not expand.

+        Tensor in_batch = input->Slice(i, i + 1).Resize(input_shape);
+        Tensor out_batch = output->Slice(i, i + 1).Resize(output_matrix_shape);
+        for (int g = 0; g < groups; g++) {


for (int i = 0; i < batch_size; i++) { // .... for (int g = 0; g < groups; g++) { if(!IsExpand) { ShareDataWith(); } else if () { im2col(); } else if () { im2vol(); } } }

+            math::matmul<Place, T>(context.device_context(), filter_slice, true,
+                                   out_grad_slice, false, T(1.0), &col_matrix,
+                                   T(0.0));


The code structure is same as above.

+                          1,
+                      col_width,
+                      "col_width and padding(padding_left, padding_right) are "
+                      "inconsistent.");


写functor的��候，我也在考虑functor里面是否还有必要再次check shape的正确性，因为要么是在Op里计算得到的，要么InferShape里也已经check过。

是的，我也有想过这些，比如在Op里面检测过了，在GradOp中就不用检测了吧

-                  int padding_down, int padding_left, int padding_right) {
+                  int dilation_h, int dilation_w, int stride_height,
+                  int stride_width, int padding_up, int padding_down,
+                  int padding_left, int padding_right) {


Maybe std::vector<int>& dilations, std::vector<int>& strides, std::vector<int>& paddings are short. And the op also uses std::vector<int>.

+  int output_size = (input_size + padding_up + padding_down -
+                     (dilation * (filter_size - 1) + 1)) /
+                        stride +
+                    1;


const int dkernel = dilation * (filter_size - 1) + 1; const int output_size = (input_size + padding_up + padding_down - dkernel)/stride + 1;

+                      "input_width and output_width are "
+                      "Mismatching.");


Same as above, whether it needs to check again?

I think we can write in this way first, and discuss it later. Because other functors also have similar problem.

+                     output_height +
+                 h_col) *
+                    output_width +
+                w_col;


data_col_index的计算太长，不容易看清楚。一些计算可以移到各自循环里。

把这个公式分成了两个，现在可能会好一点
