keras运行报错ValueError: Graph disconnected: cannot obtain value for tensor Tensor(“input_1:0”, shape=(?, 64, 64, 3), dtype=float32) at layer “input_1”. The following previous layers were accessed without issue: []

图中画圈的位置不可以继续使用Input()使用的参数名,需要重新使用一个参数名即可:
原始函数如下:
keras运行报错ValueError: Graph disconnected: cannot obtain value for tensor Tensor
修改后如下:
