Python 无法在Google Colab中将ML模型保存到Google驱动器

下面是我用来保存模型的函数。文件夹“models”不存在。但是它不应该创建一个文件夹“models”并将模型保存为文件名。我在任何地方都找不到解决办法

# Create a function to save a model
def save_model(model, suffix=None):
  """
  Saves a given model in a models directory and appends a suffix (str)
  for clarity and reuse.
  """
  # Create model directory with current time
  modeldir = os.path.join("/content/drive/My Drive/Dog Eyes/models/",
                          datetime.datetime.now().strftime("%Y%m%d-%H%M%s"))
  model_path = modeldir + "-" + suffix + ".h5" # save format of model
  print(f"Saving model to: {model_path}...")
  model.save(model_path)
  return model_path

我调用函数的方式如下

# Save our model trained on 1000 images
save_model(model, suffix="1000-images-mobilenetv2-Adam")

这是我在执行函数时遇到的错误

Unable to create file (unable to open file: name = '/content/drive/My Drive/Dog Eyes/models/20200306-18501583520636-1000-images-mobilenetv2-Adam.h5', errno = 2, error message = 'No such file or directory', flags = 13, o_flags = 242)

完整的错误消息

文件夹“models”未创建，这似乎是问题所在。手动创建“models”文件夹将解决此问题，并且模型将保存在正确的路径中
