我一直在训练模型，使用htop可以看到内存每次迭代都在增加。环顾四周，大多数人说图必须继续增长，因为我每次迭代都会加载新模型，或者因为我添加了新操作，但以上都不做。 这是最小的可复制示例。

from tensorflow.keras.layers import Dense
from tensorflow.keras.optimizers import Adam
import tensorflow as tf
import numpy as np

#%% Params
OBSERVATION_SPACE_VALUES = 4
actION_SPACE_SIZE = 2
LEARNING_RATE = 0.00025/4
DENSE_PARAMS = [256]

class Network():
    def __init__(self,state_size=OBSERVATION_SPACE_VALUES,action_size=actION_SPACE_SIZE,learning_rate=LEARNING_RATE,dense_params=DENSE_PARAMS):

        self.state_size = state_size
        self.action_size = action_size
        self.learning_rate= learning_rate        
        self.model = self.create_model(dense_params)

    def create_model(self,dense_params=[256]):

        model = Sequential()
        for params in dense_params:
            units = params
            model.add(Dense(units,activation='relu',input_shape=[self.state_size]))

        model.add(Dense(self.action_size,activation="linear"))
        model.compile(loss="mse",optimizer=Adam(lr=self.learning_rate))
        return model

Agent = Network()

for i in range(10_000):
    state = np.random.rand(Agent.state_size)
    state = np.expand_dims(state,axis=0)
    output = np.random.rand(Agent.action_size)
    output = np.expand_dims(output,axis=0)
    Agent.model.fit(state,output,verbose=True)
