cv2.imread（）读取的图文维度存在随机性

[XFNxiaofuni]

Expected behaviour

Write here how did you expect the library to function.

Actual behaviour

(160, 256) (160, 256, 1) (160, 256) (160, 256, 1)

和

(160, 256) (160, 256, 1) (160, 256, 1) (160, 256, 1)

多次运行，会不断改变，我不太明白是什么原因。我希望能保持单通道的1这个参数，在我的结果里。

Steps to reproduce

fundus_img = cv2.imread('/root/autodl-fs/Imag_split/processed_data/1-1 dose/0_0.jpg', cv2.IMREAD_GRAYSCALE) print(fundus_img.shape) name = np.expand_dims(fundus_img, axis=2) print(name.shape) nameimg = name.astype(np.float32) nameimg2 = img_train_transforms(nameimg) print(nameimg2.shape) if len(nameimg2.shape) != 3: nameimg2 = np.expand_dims(nameimg2, axis=2)

print(nameimg2.shape)

Issue submission checklist

• [ ] This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
• [ ] I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
• [ ] The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
• [ ] I'm using the latest version of opencv-python
