Question

我正在尝试为猫狗分类创建一个Tensorboard，但是无法创建目录。

由于某种原因，如果我删除.format（NAME），它会运行一秒钟，但仍然会引发错误。它设法创建以下路径：日志->火车-> events.out.tfevents.1571558167.DESKTOP-TI1MJRC.2216.327.v2

import pickle
import tensorflow as tf
from tensorflow import keras
from tensorflow.keras.callbacks import TensorBoard
import time

NAME = 'Cats-vs-dog-cnn-64x2{}'.format(int(time.time()))

tensorboard = TensorBoard(log_dir='logs/{}'.format(NAME))

...

model.fit(X, y, batch_size=32, epochs=3, validation_split=0.2, callbacks=[tensorboard])

如果我离开.format（NAME）：

如果我删除.format（NAME）：

我通过使用以下方法解决了这个问题：

import os

PATH = os.path.join('logs', NAME)
tensorboard = TensorBoard(log_dir=PATH)

如何为我的项目创建Tensorboard？
