人工智能猫狗识别程序，模板已训练完成，进行识别的时候无法找到目标文件夹，但是文件夹地址是对的

Question

问题遇到的现象和发生背景

做人工智能猫狗识别的项目，把数据集训练完了之后，找了几张照片进行验证，照片放在了一个文件夹里，程序运行的时候说没有这样的文件夹或项目

用代码块功能插入代码，请勿粘贴截图

import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'
import keras.backend as K
K.image_data_format( ) == 'channels_first'
import numpy as np
from keras.models import model_from_yaml
from keras.optimizers import Adam,SGD
from keras.preprocessing import image
from keras. applications.resnet50 import preprocess_input,decode_predictions

img_h, img_w = 150,150
image_size = (150,150)
nbatch_size = 256
nepochs = 48
nb_classes = 2

def pred_data():
    with open('cat_dog.yaml','r',encoding='utf-8') as yamlfile:
        loaded_model_yaml = yamlfile.read()
        model = model_from_yaml(loaded_model_yaml)
        model.load_weights('cat_dog.h5')
        sgd = Adam(lr=0.0003)
        model.compile(loss='categorical_crossentropy',optimizer= sgd,metrics=['accuracy'])
        images=[]
        path = 'C:/Users/11216/PycharmProjects/pythonProject/Demo/人工智能导论/猫狗识别/data/pred'
        for f in os.listdir(path):
            img = image.load_img(path + f, target_size=image_size)
            img_array = image.img_to_array(img)
            x= np.expand_dims(img_array, axis=0)
            x= preprocess_input(x)
            result= model.predict_classes(x, verbose=0)

            print(f,result[0])

pred_data()

运行结果及报错内容

附加我的文件夹
