此问题是A 'Concatenate' layer should be called on a list of at least 2 inputs的扩展。请先阅读。

使用多个时，我现在收到上述错误 操作“图层”。奇怪的是，当我只使用1个op时，我的代码可以工作 “层”，我不知道为什么。

代码：

#Import statements
import random
import numpy as np
from tensorflow import keras
import tensorflow as tf
from tensorflow.keras import layers as L
from collections import deque
from scipy.special import spence

#Op and conv functions
def op(x,units,kernel,stride,activation):
    x_list = []
    for i in range(units):
        x_list.append(L.Conv2D(1,activation=activation)(x))
    x = L.concatenate(-1)(x_list)

    return x

def conv(x,activation):
    x = L.Conv2D(units,activation=activation)(x)
    return x

#Build_model function
    def build_model(self):
        inputx = L.Input(shape=self.state_size)
        goalx = L.Input(shape=self.state_size)
        x = L.concatenate(-1)([goalx,inputx])
        x = conv(x,4,(5,5),(1,1),activation=swish)
        x = op(x,(2,2),2,activation=swish)
        x = L.flatten()(x)
        outp = L.Dense(self.action_size,activation='softmax')(x)
        valp = L.Dense(1)(x)
        model = keras.models.Model([inputx,goalx],outp)
        critic = keras.models.Model([inputx,valp)
        model.compile(loss='msle',optimizer='adam')
        critic.compile(loss='msle',optimizer='adam')
        return model,critic
