入力を作る処理のサンプルを載せておきます。

カラー画像の場合、RGBの３チャネルあるはずなのでこのサンプル通りにはならないと思います。

tensor.h内の記述を見てみると、
|
|
166
|
+
|
|
167
|
+
```C++
|
|
168
|
+
|
|
169
|
+
/// Example:

|
172
|

|
|
173
|
+
/// ```c++

/// typedef float T;

178
|

|
|
179
|
+
/// Tensor my_mat(...built with Shape{rows: 3, cols: 5}...);
|
|
180
|
+
|
|
181
|
+
/// auto mat = my_mat.matrix<T>(); // 2D Eigen::Tensor, 3 x 5.
|
|
182
|
+
|
|
183
|
+
/// auto mat = my_mat.tensor<T, 2>(); // 2D Eigen::Tensor, 3 x 5.
|
|
184
|
+
|
|
185
|
+
/// auto vec = my_mat.vec<T>(); // CHECK fails as my_mat is 2D.
|
|
186
|
+
|
|
187
|
+
/// auto vec = my_mat.tensor<T, 3>(); // CHECK fails as my_mat is 2D.
|
|
188
|
+
|
|
189
|
+
/// auto mat = my_mat.matrix<int32>();// CHECK fails as type mismatch.
|
|
190
|
+
|
|
191
|
+
///

|
192
|

|
|
193

|
+
|
|
195
|
+
```
|
|
196
|
+
|
|
197
|
+
この中で言えば
|
|
198
|
+
|
|
199
|
+
```C++
|
|
200
|
+
|
|
201
|
+
auto vec = my_mat.tensor<T, 3>(); // CHECK fails as my_mat is 2D.
|
|
202
|
+
|
|
203
|
+
```
|
|
204
|
+
|
|
205
|
+
に該当するのかなと考えましたがそれを確証づけることができませんでした。
