ModuleNotFoundError:没有名为“模型"的模块

本文介绍了ModuleNotFoundError:没有名为“模型"的模块的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个具有以下结构的软件包:

I have a package with the following structure:

model\
    __init__.py (from model.main_trainer import *, etc.)
    main_trainer.py
    snn.py
    splitter.py

main_trainer.py脚本至少接受三个参数作为输入:

The main_trainer.py script takes at least three arguments as inputs:

#main_trainer.py

import numpy as np # Linear algebra
import pandas as pd # Data wrangling
import re # Regular expressions

import matplotlib


# Avoid plotting graphs
matplotlib.use('Agg')

# Custom dependencies
from model.snn import *
from model.splitter import *

def main_trainer(dataset_name, model_dict = None, train_dict = None,
                 how = 'k-fold cross-validation', save = True):
    etc.

if __name__ == '__main__':
    dataset_name, model_dict, train_dict, how = sys.argv[1], sys.argv[2], sys.argv[3], sys.argv[4]
    main_trainer(dataset_name, model_dict, train_dict, how)

但是，如果我在终端中运行以下内容:

However, if I run in the terminal the following:

python main_trainer.py dataset_name model_dict train_dict 'k-fold cross-validation'

我收到以下错误:

Traceback (most recent call last):
  File "main_trainer.py", line 17, in <module>
    from model.snn import *
ModuleNotFoundError: No module named 'model'

另一方面，如果我这样使用相对路径:

On the other hand, if I use the relative path as such:

# Custom dependencies
from .snn import *
from .splitter import *

我收到此错误:

Traceback (most recent call last):
  File "main_trainer.py", line 17, in <module>
    from .snn import *
ModuleNotFoundError: No module named '__main__.snn'; '__main__' is not a package

我也尝试过将其运行为:

I have also tried running it as:

python -m main_trainer ...

然后出现此错误:

Traceback (most recent call last):
  File "/home/kdqm927/miniconda3/envs/siamese/lib/python3.7/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)
  File "/home/kdqm927/miniconda3/envs/siamese/lib/python3.7/runpy.py", line 85, in _run_code
    exec(code, run_globals)
  File "/projects/cc/kdqm927/PythonNotebooks/model/main_trainer.py", line 17, in <module>
    from .snn import *
ImportError: attempted relative import with no known parent package

我检查了这些帖子无济于事: ModuleNotFoundError:__main__不是软件包是什么意思? ， Python 3中的相对导入

I have checked these posts to no avail:ModuleNotFoundError: What does it mean __main__ is not a package?,Relative imports in Python 3

推荐答案

在脚本/模块路径上添加sys模块，然后导入子模块.

Append your script/module path with sys module then import your sub modules.

sys.path.append('/path/to/your/model/modules/')

希望这可以解决您的问题.

Hope this will solve your problem.

修改了main_trainer文件

#main_trainer.py

import numpy as np # Linear algebra
import pandas as pd # Data wrangling
import re # Regular expressions
import sys
import matplotlib


# Avoid plotting graphs
matplotlib.use('Agg')

# Custom dependencies
sys.path.append('/projects/cc/kdqm927/PythonNotebooks/model/') #folder which contains model, snn etc.,
from snn import *
from splitter import *
