问题背景： pycharm运行tensorflow的测试代码时出现了这个问题，没有看懂是什么问题。恳请指导一下
代码
import tensorflow as tf
tf.compat.v1.disable_eager_execution()
hello = tf.constant('hello,tensorflow')
sess= tf.compat.v1.Session()
print(sess.run(hello))
运行结果及报错内容

前面两个问题我查到说是要么只能加代码忽略，要么从源代码安装，这个源代码安装没理解是什么意思。主要是第三个为什么说是这个优化通道不能调用呢？
想把那个通道调用了，不知道是不是已经是GPU运行的tensorflow。
