tensorflow.python.framework.errors_impl.NotFoundError: Failed to create a directory: ../user_data\co

0. Preface

Nonsense about the problems encountered by tensorboard : It was clear before, I don't know why I got a convulsion today.

1. Text

Part of the code is as follows

tensorboard_dir = os.path.join('../', 'user_data', 'code2_output', 'tensorboard')
if not os.path.exists(tensorboard_dir):
    os.makedirs((tensorboard_dir))

# 回调函数
callbacks = [
    TensorBoard(log_dir=tensorboard_dir),
    ModelCheckpoint(output_model_file, save_best_only=True, save_freq='epoch'),  # 保存模型频率
    ReduceLROnPlateau(factor=0.5, patience=3),  # 学效率下降
    EarlyStopping(min_delta=1e-3, patience=10)  # 早停
  ]

The error is as follows:

tensorflow.python.framework.errors_impl.NotFoundError: Failed to create a directory: ../user_data\code2_output\tensorboard\train\plugins\profile\2021-02-06_21-57-28; No such file or directory

Solution

1. Manually create and save the tensorboard folder
2. The folder uses logs instead of my code above, the following code
3. The folders are connected with os.path.join, as in the code above
4. Directory folder uses "\" instead of "/"

---

tensorboard_dir = os.path.join('../', 'user_data', 'code2_output', 'logs')

Description

I used the fourth method above to solve the problem. The
following code tests are OK

tensorboard_dir = os.path.join('..\\user_data\\code2_output\\tensorboard')

tensorboard_dir = os.path.join(r'..\user_data\code2_output\tensorboard')

tensorboard_dir = os.path.join('..\\', 'user_data', 'code2_output', 'tensorboard')
