无法导入实用程序和生成器包 [英] Unable to import Utils and Generators package

问题描述

我已经提到了这些帖子 1 ， 2 ，3 ， 5

I already referred these posts 1, 2, 3, 4, 5

，但仍然无法解决此问题.可能是因为其他问题过于技术性.

but am still unable to fix this issue. Might be because the other issues are too technical.

我做了以下

a)我启动了jupyter笔记本(将文件保存在桌面中)

a) I launched the jupyter notebook (save the file in Desktop)

b)导入了常规软件包，例如Pandas，Numpy，Scipy等.

b) Imported regular packages like Pandas, Numpy, Scipy etc.

c)后来我尝试导入 Utils 和 Generators 程序包，但这引发了错误.

c) Later I tried importing Utils and Generators package but it threw error.

pip install Utils  #success
pip install Generators #success
pip list-v #returned the below location

utils 1.0.1     c:\users\test\appdata\local\continuum\anaconda3\lib\site-packages pip
generators 2020.4.27 c:\users\test\appdata\local\continuum\anaconda3\lib\site-packages pip

When I tried importing `Utils` and `Generators` package, I get the same error as well

import psycopg2
import pandas as pd
import numpy as np
import Utils
import Generators

ModuleNotFoundError: No module named 'Utils'
ModuleNotFoundError: No module named 'Generators'

导入 Utils 包是否需要其他文件?

Does importing Utils package require any other file?

为什么人们经常谈论成功导入utils的项目目录?我只是想像 Pandas 那样导入它，而不在乎项目目录.我刚刚启动了jupyter笔记本，并尝试安装 Utils 软件包

Why is that people often talk about project directory for importing utils successfully? I am just trying to import it like Pandas which doesn;t care about project directory. I just launched a jupyter notebook and trying to install Utils package

如何成功导入这些软件包?这些软件包不能像 pandas 这样的常规软件包那样导入吗?因为我安装了所有那些全新的软件包，并且都成功导入了

How can I import these packages successsfully? can't these packages be imported like regular packages such as pandas? Because I installed all those packages brand new and they all are imported successfully

我也在此任何有关如何解决此问题的教程或步骤对我的学习都是非常有帮助的.

Any tutorial or steps on how can this be resolved would really be helpful for me to follow.

推荐答案

import 语句是区分大小写的，而 pip 是不区分大小写.

import statements are case sensitive while the pip is case insensitive.

根据 PEP-0426 描述了一种发布和交换与Python发行版/软件包相关的元数据的机制，

According to PEP-0426 which describes a mechanism for publishing and exchanging metadata related to Python distributions/packages,

所有分发名称的比较必须不区分大小写，并且必须考虑连字符和下划线是等效的.

All comparisons of distribution names MUST be case insensitive, and MUST consider hyphens and underscores to be equivalent.

因此从技术上讲， pip install Utils ， pip install UTILS 或 pip install utils 都将安装名为 utils的相同发行版/软件包..

So technically pip install Utils, pip install UTILS or pip install utils will all install the same distribution/package named utils.

要解决此问题，您必须将代码从更改为

To fix the problem you have to change your code from

import Utils
import Generators

到

import utils
import generators
