如何安装pylab
模块,我对其进行搜索并发现它是其中的一部分matplotlib
,但是我不知道应该安装哪个版本的matplotlib
。 I try to install the newest version, it reminds me to update many module version. 我尝试安装最新版本,它提醒我更新许多模块版本。 But I need to control the version of modules.
但是我需要控制模块的版本。
When I run a python scripts written by others, I controlled module version by creating a new environment using Anaconda
. 当我运行别人编写的python脚本时,我通过使用
Anaconda
创建新环境来控制模块版本。
This is the scripts documentation. 这是脚本文档。
The software requires the following python libraries (and their
associated dependencies) to be installed. The version numbers used
are identified, other versions may also work, but results may be
slightly different.
- numpy (1.7.0)
- scipy (0.11.0)
- pandas (0.12.0)
- scikit-learn (0.14.1)
- pybedtools (0.6.4)
- tabix (0.2.5)
I installed all module in the README
. 我在
README
安装了所有模块。

Any help? 有什么帮助吗?
virtualenv is the usual way to avoid the library versioning problem with Python. virtualenv是避免Python版本库问题的常用方法。
From the documentation: 从文档中:
virtualenv is a tool to create isolated Python environments.
virtualenv是用于创建隔离的Python环境的工具。
The basic problem being addressed is one of dependencies and versions, and indirectly permissions.
解决的基本问题是依赖项和版本之一,以及间接权限。 Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications?
假设您有一个需要使用LibFoo版本1的应用程序,但是另一个应用程序需要版本2。您如何同时使用这两个应用程序? If you install everything into /usr/lib/python2.7/site-packages (or whatever your platform's standard location is), it's easy to end up in a situation where you unintentionally upgrade an application that shouldn't be upgraded.
如果将所有内容都安装到/usr/lib/python2.7/site-packages(或平台的标准位置是什么)中,那么很容易在无意中升级不应升级的应用程序的情况下结束。
Or more generally, what if you want to install an application and leave it be?
或更笼统地说,如果您要安装应用程序并保留原样该怎么办? If an application works, any change in its libraries or the versions of those libraries can break the application.
如果应用程序正常运行,则其库或这些库的版本中的任何更改都可能破坏该应用程序。
I use conda search matplotlib
to find all the version of matplotlib
. 我用
conda search matplotlib
找到的所有版本matplotlib
。

1.2.1 np16py26_1 defaults
1.2.1 np16py27_1 defaults

1.3.1 np17py26_0 defaults
1.3.1 np17py27_0 defaults
1.3.1 np17py33_0 defaults
And choose one version (such as 1.3.0) that seems support the numpy17
. 然后选择一个似乎支持
numpy17
版本(例如1.3.0)。 It works after installing 1.3.0 version of matplotlib
! 在安装1.3.0版本的
matplotlib
之后,它可以工作!
