Could you run in a terminal

spyder --reset

and try again?

[mtkilic]

I have the same issue. I open Anaconda Launcher and right next to Spyder, update button shown. After I updated. And try to click spyder to Launch nothing comes up. I have version 2.3.8. I am using Mac

[mtkilic]

@ccordoba12 @jdweaver Thank you spyder --reset worked!

First reset your laptop/PC, after that open terminal and type spyder --reset

[jdweaver]

Same issue :(

[mtkilic]

@jdweaver make sure you updated to latest version first. Then reset your PC, before opening Anaconda or Spyder, open your terminal and dospyder --reset After that try to open spyder. It should work, because it looks like we had exact same issue. Good luck!

[ccordoba12]

@jdweaver, could you upload somewhere (e.g. as a gist) or send me directly (my email is under my Github user page) this file

 C:\Users\jdweaver\.spyder2\spyder.ini

?

That would really help me to debug and solve this problem :-)

[Nodd]

This is a recurring problem. We should catch the exception, warn the user and asks if he wants to reset the settings and restart spyder. I thinnk that it should be done even if we find the root of the problem, because spyder should be able to start even if the .ini is corrupted.

[jdweaver]

@ccordoba12
I was able run spyder --reset but it still isn't resolving the issue.

I'm also not seeing the spyder.ini file, it looks like it might gotten removed from the spyder reset...
I'll send you the other file it might be

[jdweaver]

@mtkilic was updated...i had to re-update my BIOS yesterday and now the reset worked but I'm still getting the same behavior. I click on the Spyder app directly or through the Anaconda Navigator and it looks like Spyder will load, but then it doesn't _sad panda_

[jdweaver]

@ccordoba12 So I think I figured it out. There was an issue where some additional string got added to my spyder.ini file.

I followed the path: C:\Users.spyder2\spyder.ini and edited the file. I removed the end string "curso" and then was able to launch Spyder.

Not sure how that string got in the .ini file...but it seems to be working now.

[ccordoba12]

@jdweaver, glad to know you solved the problem :-)

[KeithBrodie]

Just in case it helps, I installed clean python 3.5 from python.org on Windows 10, then pip installed spyder. It failed silently. I then pip installed PyQT5, uninstalled and reinstalled spyder - and it works.

[Apurva018]

Spyder doesn't launch what to do

[abhinav19792]

Try giving firewall access to python and check environment variables.

[SagarPohekar]

Guys,
I have observed the same problem:
Solution: Uninstall PyQt and then uninstall the SIP package
Reinstall above packages but in following sequence:
1 SIP
2 PyQt4/5
Try to launch Spyder, it works
I have tested this on Python 3.5.2 and 3.6.2

[MBiagio]

I have the same problem. Spyder looks like it is going to launch and then doesn't. I tried spyder --reset, but it does nothing. This was a newly re-installed version after it didn't work the first time either.

Unfortunately I have no idea how to do what you said Sagar?

[axil]

@MBiagio I had the same problem, pip install pyqt5 helped (windows 7, python 3.6).

[MBiagio]

I don't know what pip install is, or what pyqt5 is. But I tried running spyder from the terminal and it worked.

[VT-SCM]

@axil this worked for me.

[ccordoba12]

This is going to be fixed in our 3.2.5 version. Thanks for your patience.

[salmanozi]

I downloaded anaconda recently and since then I couldn't lunch spyder, though I have an existing spyder in winpython before downloading anaconda as a result of the difficulty I am experiencing the winpython was uninstalled yet when I attempt opening spyder the old one comes up and prevent me from accessing new/fresh console, below is the error or respond that comes up when try to open from the only existing spyder page

File "C:\Anaconda\lib\site-packages\spyder\plugins\editor.py", line 1711, in new

FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\suleiman abdullahi\.spyder-py3\template.py'

[obluesky]

I have no clue what pip install pyqt5 is but it solved my problem. Thanx @axil !

[ayofolaposy]

I had the same problem with Spyder 3.2.3 and upgraded to 3.2.6 but nothing worked. I ran pip install pyqt5 from the terminal and then launched Spyder from Anaconda and it worked! Thanks everyone for sharing!

[Pechi77]

I have the same issue, If I try spyder --reset I get this error C:\Users\PA5027251>spyder --reset Traceback (most recent call last): File "C:\ProgramData\Anaconda3\Scripts\spyder-script.py", line 3, in <module> import spyder.app.start File "C:\ProgramData\Anaconda3\lib\site-packages\spyder\app\start.py", line 7, in <module> import socket File "C:\ProgramData\Anaconda3\lib\socket.py", line 49, in <module> import _socket ImportError: DLL load failed: Access is denied. pls help

[peopzen]

I think my spyder 3.2.7 worked fine before, but it refuses to start today. so I upgrade it to 3.2.8, it still doesn't start. It shows "start circle", and then nothing happens. I run (Win7, py3.5.4) "spyder3.exe --reset", but doesn't help.
How to fix the issue? Where to find log information to identify issue? Thanks.

[anitakh1]

spyder is not opening from anaconda prompt. i tried spyder --reset but it gave this error

i followed many posts but my problem is not getting rectified. i can't reinstall anaconda as i have many things installed on this. pl help me.

[ccordoba12]

It seems you corrupted your installation somehow. I think you have no other option but to reinstall.

[SHIVAMGUPTA24]

dont know what happened .

[isaacgg]

Same problem here, except that when I do spyder --reset I got a "Python has stopped working" prompt.
I'm working on Windows.

Any thoughts here?

[fgeorgoulis]

facing exactly the same issue as SHIVAMGUPTA24 from yesterday...tryed everything mentioned in the forum without any result.

[dexter-egocentric]

spyder --reset doesn't work.
pip install pyqt5 worked.

[pjk645-zz]

When I installed tensorflow via conda it killed spyder's ability to launch.
Versions:
Windows 7 Enterprise
Python 3.6.5
conda 3.5.4
Installer: Anaconda3_5.2.0-Windows-x86_64.exe
tensorflow 1.8.0-py36_1

After installing tf, when I tried to run spyder, it would open two instances of pythonw.exe for about ten seconds while an hour glass appeared net to the mouse. Then the instances disappeared silently and no instance of the spyder gui appeared. I tried resetting spyder as mentioned above and that didn't do it.

I think it is due to tensorflow downgrading pyqt from 5.9.2 to 5.60-py36_2 because after I uninstalled and reinstalled tf, I ran >conda update pyqt and spyder started working again. The update took pyqt from 5.6.0-py36_2 to 5.6.0-py36_5 and now spyder works. It also downgraded sip from 4.19.8-py36h6538335_0 to 4.18-py36_1.

I didn't want to open a new issue, because it seems related to the above issues and also because I was able to hack a solution. However, hopefully this helps future users.

[LA1824]

I have been getting this window, but the spyder interface is not loading up.
Anaconda Navigator 1.8.7
Spyder 3.2.8
Windows 10 64-bit
It seems the spyder is running, but it doesn't show on screen.
Tried everything reset, installing pyqt5, show console, re-installation, spyder upgrade.
Tried opening it with terminal and it doesn't throw any error, rather it showed me the same screen attached image.

[rb1990]

I have the same identical problem of @LA1824 . This is the error that I get (i guess is the same one). Can someone please help us? I really don't know what to do. I am trying to solve this problem for days. We got the window like if it is opening but then nothing appear on the screan. help us, please. P.s. I've also tried to install with different permission, but I'm still getting the same error.

[ccordoba12]

@rb1990, you have two Python installations and it seems you're mixing pip and conda packages, which is a recipe for disaster. My advice is for you to remove both Anaconda and your other Python installation, reinstall Anaconda and try again.

[rb1990]

Sorry @ccordoba12 how you can tell I have two Python installations? Cause I've been trying to remove everything and download again, but it's still not working. Thanks

[ccordoba12]

Look at the first two or three lines in your screenschot: you have a site-packages in ...\roaming\python\python3.6. It's not another Python installation (I thought it was); it's the installation directory used by pip install --user.

[rb1990]

cause I tried to run "pip install pyqt5" as a user in the anaconda prompt as they said here, but still didn't work.

[ccordoba12]

I can see that. But there's no need to do that because Anaconda comes with pyqt already. That's what probably led to the fatal mix of conda and pip packages.

Look, it's clear you don't understand what you're doing. Simply remove that pip directory and try again.

[rb1990]

I've just uninstalled and cleaned everything. Reinstalled and this is the same error. I need to find out what's "keyerror: 'context' " mean. If someone can please help me. Please @LA1824 let me know if you've found a solution. @ccordoba12 Of course I don't know what I am doing, that's why I am asking if someone can please help me. I'm new with these things. Sorry :)

[ccordoba12]

Of course I don't know what I am doing

What I meant is that you'r blindly copy/pasting commands without understanding their purpose. And that's really bad.

Please try now:

conda install -f zeromq pyzmq

and try again.

[rb1990]

@ccordoba12 I know, you're right and thanks for helping. Anyway, still the same identical error :( It seems no matter what I do, but it's still giving me the same problem :(

edit: the weird thing is that when I try to close anaconda navigator, it says that there is spyder running, but it doesn't show nothing on screen.

[rohitgupta]

Hi,
When i try to Launch Spyder 3.2.8 from terminal and Anaconda i can see it is Launching and running but unable to see window.

I have tried even resetting spyder --rest but no luck.

When i am trying with terminal getting below error.

Please help.

rohit@rohit-H55M-S2:~$ spyder

[rb1990]

My issue was related to an antivirus getting in the way. I just uninstalled "malwarebytes" and then install again Anaconda.

[ArunSha]

Hey guys, while trying to run spyder i get the following error:

Any help in this matter would be much appreciated

[ccordoba12]

@ArunSha, this is most probably an installation issue. So my recommendation for you is to uninstall and reinstall Anaconda again.

[LA1824]

Nope @jayrawatrj

[jayrawatrj]

I have already tried but didn’t work

Okay I am a beginner in Machine Learning and this software is already taking out all the fun out of it. So my spyder was not working and i tried reinstalling.

However now Anaconda Navigator doesnt launch. This is the error i get when I run it

spyder --reset

Didn't work on my Linux

instead

uninstall and re insatlled spyder in anaconda and it works.

[inlee12]

spyder does not launch with anaconda navigator but launch when I use in command at terminal mode

(base) C:\Users\islee>spyder
Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use:

[jingweimo]

@axil : Very neat solution! Works for me!!

[krimobe]

I have a similar issue.
Windows 7 x84
4 GB Ram
CPU: Intel (R) Core i5 2.5GHz
Python 3.7.0
conda 4.5.11
Installer: Anaconda3-5.3.1-Windows-x86

I have tried reinstalling Anaconda several times.
I have run spyder --reset.
I have removed spyder.lock files/folders.
I have downgraded the packages qt,sip,pyqt to qt-5.62,sip-4.18.1,pyqt-5.6.0
I have tried conda install -f zeromq pyzmq
I have tried changing the socket.py file in the zmq package
From previous posts it seems that it might be my anti-virus, however I am working on a company computer which runs McAfee anti-virus which I do not have the possibility to disable.
So is there a work around?

Kind regards
Kristian

[SHIVAMGUPTA24]

change pyqt5 file version might work

[cankadir]

Downgrading Spyder worked for me.

[thejipsess]

For me the issue was due to my keras installation as I installed the required keras-gpu packages before installing Spyder, to solve: create a fresh environment, install spyder and finally install keras as follows within the Anaconda Prompt:

1) _conda create -n environmentName_
2) _activate environmentName_
3) WITHIN THE ANACONDA NAVIGATOR: install spyder (I guess '_conda install -c anaconda spyder_' in the Prompt should work as well)
4) _conda install -c conda-forge keras-gpu_ (or if you don't have CUDA and want to use cpu for calculations use '_conda install -c conda-forge keras_' instead

I recommend testing the setup before adding additional packages and if adding them, ensure to close spyder and anaconda before doing so

[priyanka176]

@ArunSha, please open an Anaconda Prompt, run there

conda install qt=5.6* pyqt=5.6* sip=4.18*

and try again.

This work for me.Thanks.

[Yasine001]

I had the same issue, but it worked for after reseting :
spyder --reset

[charanjitpabla]

Hello,

I am getting this message when opening spyder in linux terminal:

Spyder is already running. If you want to open a new
instance, please pass to it the --new-instance option

What do I do to fix this?

[kouassives]

I have a similar issue:
double click

[cecidip]

@ccordoba12 if i do spyder --reset it tells:
/Users/cecidip/anaconda3/bin/pythonw: line 3: /Users/cecidip/anaconda3/python.app/Contents/MacOS/python: No such file or directory
??
I had spyder 3.3.5 and i did "conda update spyder" then i went to anaconda to launch, it didnt. But i had the option to update it.... even if i just did, so i did "update" but it actually downdated it back to 3.3.5 ... and still wont launch.
Also, when i close anaconda it says that spyder's still runing, which is not. I have rebooted the computer, nothing changed.
Please dont tell me i have to uninstall and install anaconda again, its not possible that everytime i want to update something i end up re-installing anaconda, its the 3rd time this month.

[ccordoba12]

@cecidip, please run

conda install -f python.app

That should fix your problem.

[cecidip]

conda install -f python.app did it, thanks !

[dk-raghu]

Experience installing Anaconda

• I did several trials of install and un-install Anaconda (I was just interested in launching Spyder) as a novice user of Python
• Browsed internet over and over again
• Used "conda" and "pip" several times
• Finally I un-installed the anti-virus software on my Laptop
• Un-installed Anaconda and re-installed it again and then launced Spyder FINALLY !!!!
• Works now for me

[ccordoba12]

Finally I un-installed the anti-virus software on my Laptop

This was (most probably) the critical step.

[Asgharzade]

@ccordoba12 @jdweaver Thank you spyder --reset worked!

First reset your laptop/PC, after that open terminal and type spyder --reset

Thanks dude! I was about to lose my mind on this Spyder issue. You made my day!

[rafaeldoug]

_Start Menu/Anaconda*/Reset Spyder Settings_ can works.

[mharis0014]

@ArunSha, please open an Anaconda Prompt, run there

Try installing the following:
latest spyder, sip
Pyqt5 < 5.13

and try pip install --upgrade jupyter_client
I was missing few imports and updating jupyter worked for me for latest spyder 4.1.4
