Question

我正在处理 VMMR 数据集，并且在开始为模型训练回调时遇到此错误。

from tensorflow.keras.models import Sequential, Model, load_model
from tensorflow.keras.callbacks import ModelCheckpoint, EarlyStopping, TensorBoard, CSVLogger
from tensorflow.keras import optimizers, models
from tensorflow.keras.layers import Dense, Dropout, GlobalAveragePooling2D
from tensorflow.keras import applications
from tensorflow.keras import backend as K
import tensorflow as tf
import os
from tensorflow.keras.preprocessing.image import ImageDataGenerator
from tensorflow.keras.applications.inception_v3 import preprocess_input, decode_predictions
import math
top_layers_file_path="top_layers.iv3.hdf5"

checkpoint = ModelCheckpoint(top_layers_file_path, monitor='loss', verbose=1, save_best_only=True, 
              mode='min')
tb = TensorBoard(log_dir='./logs', batch_size=val_flow.batch_size, write_graph=True, update_freq='batch')
early = EarlyStopping(monitor="loss", mode="min", patience=5)
csv_logger = CSVLogger('./logs/iv3-log.csv', append=True)

history = model.fit_generator(train_flow, epochs=5, verbose=1,validation_data=val_flow,
                              validation_steps=math.ceil(val_flow.samples/val_flow.batch_size),
                              steps_per_epoch=math.ceil(train_flow.samples/train_flow.batch_size),
                              callbacks=[checkpoint, early, tb, csv_logger]

如果你的平台是windows，试试这个

log_dir='.\logs'

手动创建文件夹应该始终有效
