原因复现：
原生的.pt 好使， 转化后的 CoreML不好使， 分类有问题。
yolov8 格式的支持情况
Format Argument Suffix CPU GPU
0 PyTorch - .pt True True
1 TorchScript torchscript .torchscript True True
2 ONNX onnx .onnx True True
3 OpenVINO openvino _openvino_model True False

sklearn不支持，tensorflow和torch没测试过，可能会有问题。 先跑跑再说吧
Loading /home/justin/Desktop/code/python_project/Jersey-Number/runs/classify/train7/weights/best.mlpackage for CoreML inference...
scikit-learn version 1.4.2 is not supported. Minimum required version: 0.17. Maximum required version: 1.1.2. Disabling scikit-learn conversion API.
TensorFlow version 2.13.1 has not been tested with coremltools. You may run into unexpected errors. TensorFlow 2.12.0 is the most recent version that has been tested.
Torch version 2.3.0+cu121 has not been tested with coremltools. You may run into unexpected errors. Torch 2.1.0 is the most recent version that has been tested.所以还要降级，真是麻烦，tensorflow是因为要转android侧的模型。
这里要给个参数，来指定cpu复现
res_number_class = model_class(cropped_image, device = "cpu")
这意思是不能用pytorch 跑了吗？ @todo， 然后用pytorch 2.0的环境试一下看看怎么样？@todo,
核心诉求是要把coreml的模型加载起来，看看是不是存在一样的错误

shit CoreML模型只能在mac 上跑， 而且只能用CoreMl 跑么？？？ @todo???
确实只能在mac上跑

一段python代码：
python

import numpy as np
def get_x1y1x2y2(coordinate,img):
width,height = img.size()
center_x = int(coordinate[0] * width)

img_w = int(coordinate[2]*width)
img_h = int(coordinate[3]*height)
return center_x, center_y, img_w, img_h
def ml_test_detect():
mlmodel = ct.models.MLModel('/Users/smkj/Desktop/Code/justin/head_person_hoop_number_v8n.mlpackage')
print(mlmodel)
img = PIL.Image.open("/Users/smkj/Desktop/Code/justin/imgs000006-raw.jpg").resize((640,384))
res = mlmodel.predict({"image":img})
confidence_max_list = list(np.array(res['confidence']).argmax(axis=1))

for row_index, class_id in enumerate(confidence_max_list):

im.save("bbb.jpg")
print(res)
# print(img)
def ml_test_classify():

max_key = max(res['classLabel_probs'], key=res['classLabel_probs'].get)
print("class_name:",max_key, "confidence:",res['classLabel_probs'].get(max_key))
a = 1
ml_test_classify()在mac上安装opencv实在是太费劲了，各位自求多福吧！
用这个可以替代opencv： pip install pillow
置信度也是99.99
coreml不爽的点是必须要固定尺寸??? @todo 也许是我用惯了动态尺寸的原因。 anyway，今天调试了一天，在两个电脑上装了环境，算是搞定了。！！！
