可视化

添加变量

tf.summary.histogram( "weights1", weights1) # 可视化观看变量

还有添加图像和音频、

常量

tf.summary.scalar('x', x)

添加embedding

python

def checkpoint(sess):

    # Output directory for models and summaries

    timestamp = str(int(time.time()))

    out_dir = os.path.abspath(os.path.join(os.path.curdir, "runs", timestamp))

    print("Writing to {}\n".format(out_dir))

    # Checkpoint directory. Tensorflow assumes this directory already exists so we need to create it

    checkpoint_dir = os.path.abspath(os.path.join(out_dir, "checkpoints"))

    checkpoint_prefix = os.path.join(checkpoint_dir, "model")

    if not os.path.exists(checkpoint_dir):

        os.makedirs(checkpoint_dir)

    saver = tf.train.Saver(tf.global_variables(), max_to_keep=FLAGS.num_checkpoints)

    saver.save(sess, os.path.join(out_dir, "model.ckpt"), 1)

合并

merged = tf.summary.merge_all()

添加视图

writer=tf.summary.FileWriter('log',sess.graph)

注意!如果Chrome打不开视图，可以尝试换个浏览器。

-- CMD下启动 去 127.0.0.1:6006 查看

tensorboard.exe --logdir=log

调试

例如下面这种简陋的方式，将要观察的变量放进去再取出来就行。

当然有更好的办法例如

code

summary, _prediction1, _logits1, _prediction_argmax1, _Y_argmax1, _X2, _correct_pred1, _accuracy1, _loss_op1 = \

    sess.run([merged, prediction, logits, prediction_argmax, Y_argmax, X, correct_pred, accuracy, loss_op],

             feed_dict={X: batch_x, Y: batch_y})

日志

复杂的变量打印是不够的，记录到本地就好了

code

handler = logging.handlers.RotatingFileHandler(LOG_FILE, maxBytes=1024 * 1024*1024, backupCount=5)  # 实例化handler

#fmt = '%(asctime)s - %(filename)s:%(lineno)s - %(name)s - %(message)s'

fmt = '%(asctime)s - %(filename)s:%(lineno)s - %(message)s'

formatter = logging.Formatter(fmt)  # 实例化formatter

handler.setFormatter(formatter)  # 为handler添加formatter

logger = logging.getLogger('tst')  # 获取名为tst的logger

logger.addHandler(handler)  # 为logger添加handler

logger.setLevel(logging.DEBUG)

logger.info('==================================')

def myLog(obj):

logger.info("obj begin===========================" + str(len(obj)))

for l1 in obj:

    # print(l1)

    logger.info(l1)
