В настоящее время я занимаюсь самообучением tensorflow и пытаюсь использовать этот код прямо здесь

 import tensorflow as tf

a = tf.constant(2.5)
b = tf.constant(4.5)
total = a   b

tf.summary.scalar("a", a)
tf.summary.scalar("b", b)
tf.summary.scalar("total", total)

merged_op = tf.summary.merge_all()

with tf.Session() as sess:
    _, summary = sess.run([sum,merged_op])
  

который должен выполняться. В настоящее время я покидаю книгу Tensorflow для чайников, и она продолжает выдавать мне эту ошибку

Каждый раз, когда я импортирую tensorflow, он всегда выдает мне огромный блок ошибок перед запуском моего кода. Как мне избавиться от этого?

sum является встроенной функцией в Python.

Использовать его в качестве имени переменной — плохая практика. Тем не менее, вы используете его, не инициализируя нигде в своем коде:

 with tf.Session() as sess:
    _, summary = sess.run([sum,merged_op])
  

Я считаю, что вам нужно заменить sum на переменную total , инициализированную выше:

 total = a   b
  

Итак, что-то вроде:

 with tf.Session() as sess:
        _, summary = sess.run([total,merged_op])
