安装 rpy2 中的难点,安装rpy2难点

参考:

1、 的Redme.md

python3中  jupyter notebook中rpy2的安装:

1、先安装R和RStudio

2、安装 rpy2  参考:

  1)      那个网站中下载rpy2的whl包

  2卡塔尔   通过pip install  xxx安装那一个包,

  3卡塔 尔(英语:State of Qatar)    python 中通过 import rpy2和  import rpy2.robjects as robjects 检查是还是不是安装成功

3、安装后现身的标题标解决办法 仿照效法:

    首若是要增加本田CR-V_HOME 和R_USE纳瓦拉的情形变量

4、jupyter notebook 中运行

      %load_ext rpy2.ipython

报错:AttributeError: 'ZMQInteractiveShell' object has no attribute 'has_readline'

找了好些个资料找不到原因,最终是透过conda install rpy2  重新安装rpy2方可化解,也许是作者事先安装的pip install whl版本不对

自从混世大魔王给本身安利了YJango的篇章后,小编就对纵深学习着迷了,那评释,其实不是DL算法太难,而是讲算法的水准一直影响了观者是否一连的欲念,倘使三个错综相连的事体能大致描述,并再提升到人生哲理,啊!基本笔者就妥胁了。

大器晚成、 安装Python 2.7.13 小编的是以此本子

以下进程全都以在Ubuntu系统下成功的!

前方高能 → Jupyter “import tensorflow” 的巨坑和什么填掉巨坑

因为是非同一般,所以必然要加粗
*初始认为装好了tensorflow,就足以在百鸟朝凤的Jupyter Notebook里喜欢玩耍Tensorflow了,结果是,把相符的代码写入到Jupyter Notebook里,它却告知自身它未有引进Tensorflow那么些模块,找了半天,终于找到领会决方案,赞!

TensorFlow website supports five installations.
To my understanding, using Pip installation directly would be fine to import TensorFlow in Jupyter Notebook (as long as Jupyter Notebook was installed and there were no other issues) b/z it didn't create any virtual environments.
Using virtualenv install and conda install would need to install jupyter into the newly created TensorFlow environment to allow TensorFlow to work in Jupyter Notebook (see the following original post section for more details).
I believe docker install may require some port setup in the VirtualBox to make TensorFlow work in Jupyter Notebook (see this post).
For installing from sources, it also depends on which environment the source code is built and installed into. If it's installed into a freshly created virtual environment or an virtual environment which didn't have Jupyter Notebook installed, it would also need to install Jupyter Notebook into the virtual environment to use Tensorflow in Jupyter Notebook.

To use tensorflow in Ipython and/or Jupyter(Ipython) Notebook, you'll need to install Ipython and Jupyter (after installing tensorflow) under the tensorflow activated environment.

Before install Ipython and Jupyter under tensorflow environment, if you do the following commands in terminal:
username$ source activate tensorflow
(tensorflow)username$ which ipython
(tensorflow)username$ /Users/username/anaconda/bin/ipython

(tensorflow)username$ which jupyter
(tensorflow)username$ /Users/username/anaconda/bin/jupyter

(tensorflow)username$ which python
(tensorflow)username$ /User/username//anaconda/envs/tensorflow/bin/python

This is telling you that when you open python from terminal, it is using the one installed in the "environments" where tensorflow is installed. Therefore you can actually import tensorflow successfully. However, if you are trying to run ipython and/or jupyter notebook, these are not installed under the "environments" equipped with tensorflow, hence it has to go back to use the regular environment which has no tensorflow module, hence you get an import error.
You can verify this by listing out the items under envs/tensorflow/bin directory:

(tensorflow) username$ conda list

You will see that there are no "ipython" and/or "jupyer" listing out.
To use tensorflow with Ipython and/or Jupyter notebook, simply install them into the tensorflow environment:

(tensorflow) username$ conda install ipython
(tensorflow) username$ pip install jupyter

After installing them, there should be a "jupyer" and a "ipython" show up in the envs/tensorflow/bin/ directory.

Notes: Before trying to import tensorflow module in jupyter notebook, try close the notebook. And "source deactivate tensorflow" first, and then reactivate it ("source activate tensorflow") to make sure things are "on the same page". Then reopen the notebook and try import tensorflow. It should be import successfully (worked on mine at least).

**根本正是,因为tensorflow的bin目录下并未安装ipython和jupyter,所以它不能够再jupyter notebook太守常import,必要额外安装ipython和jupyter包,安装成功后,通过 conda list一声令下能够见见jupyter和ipython。

末了关闭下起来张开的jupyter notebook,实施以下命令,再张开jupyter notebook就可以。

source deactivate tensorflow
source activate tensorflow

以上。

Tensorflow安装

前边讲了那么多跟Tensorflow非亲非故的条件,现在好不轻便到了着珍视了,然鹅,或者会比你想象中轻松比很多。因为自己是虚构机蒙受,未有屏息凝视的显卡,所以,独有舍弃GPU的安排,选择了独有有CPU的Tensorflow。

  • 第一步: 参照官方网站的安装步骤
    具体来讲便是之类:

    彩世界网址 3

    Installing with Anaconda

第二步:划下器重,这里会遇上二个坑,或许你到了第四步,你向来就下载不了这一个cpu版本的tensorflow,因为您连不上googleapis.com,所以,你必需得能够翻墙出去,或许说别的之处能够下载那么些文件。

Python3.6_Tensorflow只帮助CPU的本子下载路线

因为笔者设置的是Python 3.6版本,所以小编翻墙在官方网址络找到相对应的tensorflow的版本,并下载到本地windows系统,这里还会有一个坑是,下载下来到windows系统的包是zip结尾的,,,可是,只必要有个别改成.whl结尾的包,就足以在Linux下喜悦的设置了。
这里提供本身已经下载下来的版本地址,必要的心上人能够一向拿走
链接:https://pan.baidu.com/s/1kXqvnin 密码:akv1

将下载下来的包放在Ubuntu后,实行安装命令如下,就可以

pip install tensorflow-1.5.0-cp36-cp36m-linux_x86_64.whl

最终输入python代码验证下tensorflow是不是安装成功?

import tensorflow as tf
sess = tf.Session()
a = tf.constant(10)
b = tf.constant(25)
print(sess.run(a   b ))

安装成功!!!

=====================================================

1、以后python人机联作格局下和在Pycharm编辑器下都不报错了

从入门到出手感性实施,也正是绸缪八个Ubuntu的虚构景况,再接上互连网,种种下载和布局情况的进度。其实,整个进程着实非常粗大略。

  1. 从地点十三分第三方库网址下载 numpy amd64的whl文件并保存到 c:python27scripts文件夹下(小编私下认可装到C盘)

  2. cmd窗口 cd 到该文件夹,输入

    pip install numpy-xxxx mkl-cp27-none-win_amd64.whl

Jupyter Notebook

安装完结之后,直接在terminal对话框里输入

Jupyter Notebook

将会运维传说中足够好用的Jupyter Notebook,各样输入和输出都足以记录下来,好用的magic外界语法命令,并且还能援助40三种脚本语言,外加马克down的稿子证实,真是好到没朋友。呃呃呃。

Jupyter Notebook差相当少长这么

上海教室中,左边后生可畏栏的目录结构,在读者私下认可安装后,并不会产出,而是要求十分安装二个插件技巧来看,运维如下命令安装该插件,耐性等待安装,等量齐观复展开jupyter notebook,你拜谒到

conda install -c conda-forge jupyter_contrib_nbextensions

彩世界网址 7

设置Nbextensions后Jupyter大约长这么

点击这些扩充栏,然后勾选Table of Contents(2),你再度打开你的笔记*.ipynb,就能够看见如首先个图所示的右侧目录栏。

二、 先安装numpy

Anaconda安装

固然自身将来也不分明是还是不是科学念对了它的读音,然则因为它实乃过多大神推荐的旗舰款(包蕴很超多值总计的python包卡塔尔国,先不管它的得失,撸下来再说吧。

设置步骤很简短:
在Anaconda官方网站下载跟系统对应的版本,比如,自己下载的是Anaconda3-5.0.1-Linux-x86_64.sh,运维命令安装

sudo bash Anaconda2-2.5.0-Linux-x86_64.sh

设置好之后,就使用conda命令对Anaconda进行保管(那个不是生死攸关,能够不看conda那块命令使用卡塔 尔(英语:State of Qatar)

  • 更新conda
conda update conda
  • 来得可用packages
conda list
  • 从conda安装package
conda install package-name
  • 删除package
conda remove package-name
  • 更新package
conda update package-name

五、测试

c:python27python.exe  cpython27toolsscriptswin_add2path.py

 

四、 最后安装pandas

   

【成功的步骤】

3、cmd 命令张开notebook 

pip install matplotlib 
#cmd命令
jupyter notebook

彩世界网址 9

3.添扩张意况变量cmd命令

#coding:utf-8
import matplotlib.pyplot as plt
import numpy as np
X = np.linspace(-np.pi,np.pi,256,endpoint=True)
(C,S)=np.cos(X),np.sin(X)
plt.plot(X,C)
plt.plot(X,S)
plt.show()

三、再pip在线安装matplotlib

 

  1. 先卸载旧版python和相应库,删除安装文件夹,要确定保障卸载干净

  2. 装2.7.13版本去官方网址找62个人系统的安装文件,msi的后缀,装的时候不要选为全部顾客要选仅对如今顾客,笔者也没找到原因,经过五次尝试这些未有报错。

pip install pandas
pip install jupyter

由此卸载安装python多次经过折腾,参照他事他说加以考察了种种网址,终于安装成功。

2、pip 安装jupyter 

 

4、张开了叁个jupyter notebook 点击 file new 采用python 2版本输入下边代码 点击cell run ALL实行代码
