Spyder crashes at startup because of errors when importing Sympy

[TheTinka]

Hello everybody,
If I'm trying to start Spyder it always crashes and shows the attached error. It worked fine for weeks, I have no idea what it is about.
I did the reset and deleted the spyder.lock and updated spyder.
Could you please help?

Versions and main components

• Spyder Version: 3.0.2
• Python Version: 3.5.2
• Operating system: Windows 7

Thanks in advance
Tinka

I have got the same error here after upgrading to spyder3, the crash-log is as below:

I searched around for a fix, but had no luck :(

@Tuzi12, as you reported in Anaconda issues, this is an issue with PythonXY and not with Spyder itself. Since PythonXY seems unmaintained, we recommend you to use WinPython or Anaconda.

@TheTinka, please open a terminal (i.e. cmd.exe), run this command

spyder --reset

and report the error is printed there.

[Tuzi12]

@ccordoba12 Thanks for your reply and closed the other thread I opened.

But do I need to install WinPython or Anaconda first for spyder to work again?

[ccordoba12]

You need to uninstall PythonXY and install either WinPython or Anaconda. Both are Python scientific distributions, meaning that they come with Python and a lot of other scientific libraries and applications (including Spyder and all its dependencies).

WinPython is more similar to PythonXY than Anaconda, although is more focused on Python 3 than 2.

@ccordoba12 Thank you for the suggestion.

One more thing, if I uninstall PythonXY, will the Python27 comes with it uninstall as well? Since I have got some py files written in Python2, I want to make sure that I can run these files without much changes to make.

[TheTinka]

When I did the reset there is no error-message. Then Spyder is starting and shows the message from below.

[ccordoba12]

@TheTinka, there has to be some error in the terminal where you started Spyder, else that window wouldn't appear.

@Tuzi12, then you need to install Anaconda because it has very good support for Python 2 and 3.

[TheTinka]

Some hint what kind of error? I am using Anaconda and installed spyder that way to.

[TheTinka]

The reset is looking like:

[ccordoba12]

So sorry, my bad. The command is

spyder --show-console

It seems you have an old version of sympy. Please run conda update sympy and try again El 24/11/16 a las 09:29, TheTinka escribió:
