Cannot start the spyder on miniconda on WSL UBUNTU-20.04

Question

I have installed miniconda and created a virtual env with the name dataScience and installed all the required files for the spyder to work on WSL.

I have used the following commands:

1.) Spyder installation:

conda install matplotlib spyder scipy

2.) And other dependencies:

sudo apt-get install libxcursor-dev

sudo apt-get install alsa

sudo apt install libegl1-mesa libegl1

3.) And installed the X11 client on Windows 10 by downloading VcXsrv

4.) After that added the following scripts in ./bashrc:

DISPLAY=:0
export DISPLAY
export XDG_RUNTIME_DIR="/mnt/d/codes/py38/dataScience"
LIBGL_ALWAYS_INDIRECT=1
Export LIBGL_ALWAYS_INDIRECT

5.) And did source ~/.bashrc and in WSL ubuntu-20.04 LTS terminal I ran the command spyder (after starting the X server on windows10) and I got the following error:

The problem:

Am new in this field and scratching my head right now. If anyone has the solution do answer. Thank you!

Answer 1

I was able to reproduce your problem with Ubuntu 20.04 LTS. However, I was able to get Spyder to work with Ubuntu 18.04 LTS following the same instructions.

To get Ubuntu 18.04 LTS, make sure WSL is enabled on your windows machine and then download Ubuntu 18.04 LTS from the Microsoft Store.

On step 4, change Export on the last line to a lower case e.

DISPLAY=:0
export DISPLAY
export XDG_RUNTIME_DIR="/mnt/d/codes/py38/dataScience"
LIBGL_ALWAYS_INDIRECT=1
export LIBGL_ALWAYS_INDIRECT

For those who are not running within a viritualenv, export XDG_RUNTIME_DIR="/mnt/d/codes/py38/dataScience"line can be omitted.

Secondly, you also need to install the package sudo apt-get install libxss1 sudo apt-get install libxtst6 and sudo apt-get install libasound2-plugins

After that, restart your terminal. Then type spyderand everything should work. You may get warnings along the lines of libpng warning: bKGD: invalid however, these aren't critical. If you feel the need to fix them, then refer to : Incorrect rendering in Anaconda + Spyder (wrong colours in text)
