Variable conv1/weights already exists, disallowed. Did you mean to set reuse=True...tensorflow报错

在训练神经网络模型使用tensorflow时，training模块训练多次会出现报错如：

1，Variable conv1/weights already exists, disallowed. Did you mean to set reuse=True in VarScope

2，Variable conv1/weights does not exist, or was not created with tf.get_variable

都属于自己定义的网络模型的参数问题，从最前面的conv1卷积层开始报错，因为不是第一次训练模型，参数会有冲突，此时需要告诉模型可以多次训练或者理解为清除之前的一些参数

解决办法：在不是第一次的训练模块training前（或者每次训练后）加上：

tf.reset_default_graph()

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()
import os
import numpy as np
import matplotlib.pyplot as plttf.reset_default_graph()
