#path for saving the best weights
checkpoint_best_path =r'C:\Users\Administrator\Desktop\Desktop\Work\Data Science\Practice\Machine Learning\Deep Learning\Custom Deep Learning\Deep Learning with Computer vision\Basics\Covid 19 Project\Model\Model best checkpoint'
check_bestpoint = ModelCheckpoint(filepath=checkpoint_best_path, save_weights_only=True, save_freq='epoch',

#tensorboard path
log_dir_path =r'C:\Users\Administrator\Desktop\Desktop\Work\Data Science\Practice\Machine Learning\Deep Learning\Custom Deep Learning\Deep Learning with Computer vision\Basics\Covid 19 Project\Data\logs/'
log_dir = os.path.join(log_dir_path, datetime.datetime.now().strftime("%Y%m%d-%H%M%S"))
tensorboard_callback = tf.keras.callbacks.TensorBoard(log_dir=log_dir,histogram_freq=1)
callbacks= [early_stopping, learning_rate_reduction,check_bestpoint,tensorboard_callback]但我有个错误说：
C:\Users\Administrator\Desktop\Desktop\Work\Data NotFoundError:未能创建一个NewWriteableFile：

检查正在尝试保存权重以存在的文件夹。
如果它不存在，可以使用路径库创建它，如
from pathlib import Path
#tensorboard path
log_dir_path =r'C:\Users\Administrator\Desktop\Desktop\Work\Data Science\Practice\Machine Learning\Deep Learning\Custom Deep Learning\Deep Learning with Computer vision\Basics\Covid 19 Project\Data\logs/'
log_dir = os.path.join(log_dir_path, datetime.datetime.now().strftime("%Y%m%d-%H%M%S"))
Path.mkdir(Path(log_dir), exist_ok=True, parents=True)
tensorboard_callback = tf.keras.callbacks.TensorBoard(log_dir=log_dir,histogram_freq=1)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
