“ NameError：未定义名称'session_conf'”，当试图在google colab中获得可再现的结果时

Question

我尝试使用以下代码在Google Colab中获得可重复的结果。但出现错误“ NameError：未定义名称'session_conf'”。

import numpy as np
import tensorflow as tf
import random as rn

import os
os.environ['PYTHONHASHSEED']='0'
np.random.seed(1)
rn.seed(1)

from keras import backend as K

if 'tensorflow' == K.backend():
  import tensorflow as tf
  from keras.backend.tensorflow_backend import set_session
  config = tf.ConfigProto()
  config.gpu_options.allow_growth = true
  config.gpu_options.allow_growth = True
  config.gpu_options.visible_device_liste = "0"
  set_session(tf.Session(config=config))

tf.set_random_seed(1) 
sess = tf.Session(graph=tf.get_default_graph(), config=session_conf)   
K.set_session(sess)   


!pip install -U -q PyDrive
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth
from oauth2client.client import GoogleCredentials 

auth.authenticate_user()
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)

有人知道原因吗？

您尚未在session_conf行中声明变量sess = tf.Session(graph=tf.get_default_graph(), config=session_conf)。
