如何在訓練時嘗試保存模型權重時修復“無法創建文件”錯誤

Question

我在訓練時正在做圖像字幕項目我嘗試在每個時期之后通過 model.save('./model_weights1/model_'+ str(i) + '.h5') 保存模型權重，但我得到錯誤

它返回

無法創建文件（無法打開文件：name = './model_weights1/model_0.h5', errno = 2, error message = 'No such file or directory', flags = 13, o_flags = 602）

我檢查了目錄路徑是否存在，路徑似乎也是正確的

代碼：

for i in range(epochs):
    generator = data_loader(train_descriptions,encoded_images,maxlen,batch_size,word_to_idx)
    model.fit_generator(generator,epochs=1,steps_per_epoch=steps,verbose = 1)
    model.save('./model_weights1/model_'+ str(i) + '.h5')

Answer 1

你有路徑問題

做

import os
os.getcwd()

知道當前的工作目錄。 然后改變

model.save('./model_weights1/BLABLABLA)

有好的路徑

Answer 2

如果你只是想節省重量，那就更容易了

import os

然后定義您的 wights_path 並保存它們：

weights_path = os.getcwd() + "\\model_weights\\your_model.h5"
model.save_weights(weights_path)

Answer 3

經過數小時的搜索，這是有效的。 您需要輸入完整的文件路徑。 例如， /home/Desktop/Your_Directory/
