spyder安装+使用中的问题_runtimeerror: method 'detach' already has a docstr

如该有其他的什么问题欢迎大家留言！

一、spyder的安装指令

方法1、在安装之前，最好安装以下python常用库和依赖：

sudo apt-get install python-dev python-pip libxml2-dev libxslt1-dev zlib1g-dev libffi-dev libssl-dev  
sudo pip install scrapy  
sudo apt-get install libzmq-dev  
sudo pip install pyzmq #here  
sudo pip install pygments  
sudo apt-get install qt4-dev-tools qt4-doc qt4-qtconfig qt4-demos qt4-designer  
sudo pip install qtconsole  
sudo pip install ipython 

然后安装：

sudo apt install spyder     #安装spyder2
 
sudo apt install spyder3    #安装spyder3

spyder的卸载：

sudo apt-get remove spyder

运行时报错，

sudo apt-get install python3-pyqt*

方法2：

sudo apt-get install python3-pyqt5 python-sphinx
sudo apt-get install python3-pyqt*
sudo pip3 install spyder               #安装spyder3

 方法3：

sudo pip3 install -U spyder

然后会出错:psutil/_psutil_linux.c:12:20: fatal error: Python.h: 没有那个文件或目录

解决办法:

sudo apt-get install python3-dev

接着在重复指令:sudo pip3 install -U spyder

最后:sudo apt-get install python3-pyqt*

二、spyder使用过程中遇到的问题

1、问题描述：

Traceback (most recent call last):
 
  File "<ipython-input-3-bc7ab1fdfb9b>", line 1, in <module>
    runfile('/Users/aaa/.spyder-py3/temp.py', wdir='/Users/aaa/.spyder-py3')
 
  File "/usr/local/lib/python3.6/site-packages/spyder/utils/site/sitecustomize.py", line 705, in runfile
    execfile(filename, namespace)
 
  File "/usr/local/lib/python3.6/site-packages/spyder/utils/site/sitecustomize.py", line 102, in execfile
    exec(compile(f.read(), filename, 'exec'), namespace)
 
  File "/Users/aaa/.spyder-py3/temp.py", line 7, in <module>
    import torch
 
  File "/usr/local/lib/python3.6/site-packages/torch/__init__.py", line 184, in <module>
    from .tensor import Tensor
 
  File "/usr/local/lib/python3.6/site-packages/torch/tensor.py", line 12, in <module>
    class Tensor(torch._C._TensorBase):
 
  File "/usr/local/lib/python3.6/site-packages/torch/tensor.py", line 170, in Tensor
    """)
 
RuntimeError: method 'detach' already has a docstring

解决方法：

tools -->preferences-->python interpreter -->set UMR excluded (not reloaded) modules 
(在其中添加reloaded moudle中的文件)

然后重启spyder就可以了（不重启还是不能使用的哟！）

2、spyder不能启动

报如下错误：

Spyder crashed during last session.
 
If Spyder does not start at all and before submitting a bug report, 
please try to reset settings to defaults by running Spyder with the command line option
 '--reset': spyder --reset
 
Warning: this command will remove all your Spyder configuration files located in 
'/Users/repair/.spyder-py3').
 
If restoring the default settings does not help, please take the time to search for
 known bugs or discussions matching your situation before eventually creating a new 
issue here. Your feedback will always be greatly appreciated.

解决方法：

pip3 install --upgrade pip
 
sudo pip3 install --upgrade setuptools
