我有以下文件结构

.
└── text_classifier
    ├── Experiment.py
    ├── __init__.py
    ├── constants.py
    ├── hyperparameters
    │   ├── Hyperparameter.py
    │   └── __init__.py
    ├── models
    │   ├── __init__.py
    │   ├── han.py
    │   └── model.py
    ├── trainers
    │   ├── __init__.py
    │   ├── dataset_trainer.py
    │   └── trainer.py
    └── utils
        ├── __init__.py
        ├── default_conf.yml
        ├── tf_utils.py
        └── utils.py

我想import text_classifier从Ipython控制台。

text_classifier/__init__.py 包含

import builtins
import sys
import os

sys.path.append(os.path.dirname(os.path.dirname(os.path.dirname(__file__))))
sys.path.append(os.path.dirname(os.path.dirname(__file__)))
sys.path.append(os.path.dirname(__file__))
sys.path.append(__file__)

print('\n'.join(sys.path))

from .experiment import Experiment
from .hyperparameters import HP

try:
    from IPython.lib import deepreload

    builtins.reload = deepreload.reload
except:
    pass

但是import text_classifier as tcl从相同的位置运行会text_classifier产生以下结果：

ModuleNotFoundError: No module named 'text_classifier.experiment'

显然，text_classifier它位于路径（...documentation/han/text_classifier）中。任何的想法？

该Experiment.py模块具有大写字母E，但是您导入了experiment没有此模块的模块

.
└── text_classifier
    ├── Experiment.py
...

我认为你需要像这样进口

# text_classifier/__init__.py
# if you have `Experiment` class
from .Experiment import Experiment

# or simple import `Experiment` module
from . import Experiment
