PRIMAL项目，tensorflow’ has no attribute ‘variable_scope’，tf.placeholder() is not compatible tensorflow.compat.v1’

整个项目是基于tensorflow 1.x版本的。众所周知，tf 1.0 和 2.0 的兼容有点差。

AttributeError: module ‘tensorflow’ has no attribute ‘variable_scope’

Traceback (most recent call last):

解决方案：使用compat接口

tf.compat.v1.variable_scope

类似的错误

AttributeError: module 'tensorflow' has no attribute 'variable_scope'
AttributeError: module 'tensorflow' has no attribute 'Session'
AttributeError: module 'tensorflow' has no attribute 'ConfigProto'
AttributeError: module 'tensorflow' has no attribute 'GPUOptions'

tf.placeholder() is not compatible with eager execution.

参考文章：TensorFlow报错：tf.placeholder() is not compatible with eager execution.，内容详细。

Traceback (most recent call last):
  File "primal_testing.py", line 133, in <module>
    primal=PRIMAL('model_primal',10)
  File "primal_testing.py", line 25, in __init__

  File "/root/WorkSpace/PRIMAL/ACNet.py", line 25, in __init__
    self.inputs = tf.placeholder(shape=[None,4,GRID_SIZE,GRID_SIZE], dtype=tf.float32)
  File "/root/miniconda3/envs/myconda/lib/python3.8/site-packages/tensorflow/python/ops/array_ops.py", line 3268, in placeholder

解决方法：

在调用tf.placeholder()方法之前使用该语句。

tf.compat.v1.disable_eager_execution()
1

即

tf.compat.v1.disable_eager_execution()
self.inputs = tf.placeholder(shape=[None,4,GRID_SIZE,GRID_SIZE], dtype=tf.float32)

AttributeError: module ‘tensorflow.compat.v1’ has no attribute ‘contrib’

这个问题最难解决：

原因是tensorflow1.x的contrib包被整合进了2.0的其他包里。

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

最基本的解决方法
