[Bug] Incorrect text angle detection & OCR runtime error when Enable180Classification is True #174
Description
Description
The OCR engine fails to correctly identify the orientation of the text. 0° text is detected as 90°, or the detection angle is completely wrong, leading to poor recognition results. May duplicated with #170 .
(文字角度检测失败。旋转的文本（如90度或180度）被错误识别为0度，或者识别出的角度完全错误，导致最终识别结果乱码。 可能与 #170 是同一个问题)
And the second issue, When I set Enable180Classification as True, Then
(然后第二个问题是，当我设置 Enable180Classification 为 True，就会有报错，看起来是输入的维度或者尺寸不对)
