Kivy: Kivy sdl2 DLL Load failed

what does this say on your system (PowerShell):

python -m pip freeze | select-string cython

@dolang it says
'select-string' is not recognized as an internal or external command,
operable program or batch file.

yeah, sorry that wasn't clear. You need to execute that in PowerShell. It's the replacement for the DOS prompt.

Use Win + x then select it, or type powershell at the command prompt. You will have PS as the first 2 letter of the prompt.

Oh okay. In the powershell it says

Cython==0.27.3

Alright, tried to reproduce it with a similar not same environment without luck. Bascially, what the error says is that the sdl2 library is missing. But it should've been installed with python -m pip install kivy.deps.sdl2 which is in your original description somewhere.

I'll have to try reproducing this on another machine again, you could try to pip uninstall ... + pip install ... that dependency in the meantime.

Tried on another machine now, getting the same result (i.e. it works here). What do you have for:

PS  C:\> python -m pip freeze | select-string sdl2

it should give you: kivy.deps.sdl2==0.1.17.

Alternatively, if you have several Python interpreters installed:

PS  C:\> py -3.6 -m pip freeze | select-string sdl2

If one of these two commands doesn't give you the output above, try reinstalling kivy.deps.sdl2.

If they do and it doesn't work, please paste what you get with:

PS C:\> dir C:\Users\dev.DoddJ\AppData\Local\Programs\Python\Python36-32\share\sdl2\bin

Maybe you have to reinstall the 64-bit Python interpreter. (Just a guess, not sure yet.)

I did that and

get kivy.deps.sdl2==0.1.17

I have uninstalled 32-bit and installed 64-bit Python in its place, however, still get this error

Well, I wasn't sure if 32/64-bit could be the problem here. But can you look if the .dll is actually there?

PS C:\> dir C:\Users\dev.DoddJ\AppData\Local\Programs\Python\Python36\share\sdl2\bin

If it's there, maybe your virus scanner is blocking it, or your firewall (or some other really intrusive software)? This is not something that should happen, imho.

Edit: had a look at my installation again and opened a running application in Process Hacker. This SDL2.dll is custom-built for PyPI and it looks like it's unsigned. Depending on your Windows policy settings, it could be blocked automatically because of that. Maybe the following can help?

Windows 10: Unblock File in Windows 10

According to earlier comment, you have cython 0.27.3 and the console log says Kivy v1.10.0 ... those versions are not compatible, though I'm not sure exactly why the missing window provider is the first clue to this problem.... Maybe try either using cython 0.25.2 (compatible with 1.10) + reinstall kivy, or alternatively pip install kivy==master with your current cython version?

I am getting this issue also with Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 17:00:18) [MSC v.1900 64 bit (AMD64)] on win32

and I should add that this occurs even if I uninstall kivy.deps.sdl from --user mode and install it into C:\Program Files\Python\share\sdl2 via Administrator Mode, the error is the same:

````

It doesn't even work if I cd right into the directory next to SDL2.dll before running python3

Alright, there are several things at play here:

1. the .dll has to exist in that directory
2. the file ...\site-packages\kivy\deps\sdl2\__init__.py gets loaded and points at the .dll
3. Windows (or some other intrusive software like some virus scanners) itself doesn't block loading it

So far I've been unable to reproduce it, but 3. is something that can't be excluded.

Another thing you could try: open a command prompt and point the PATH directly at the sdl2 folder. Something like:

\> set PATH=C:\Users\USER\AppData\Roaming\Python\share\sdl2\bin;%PATH%

@dolang Well, it seems that adding the SDL2.dll folder to the %PATH% fixes....part of that error. img_sdl2 is now no longer "ignored", but it's still "Unable to find any valuable Window provider". It also gave some slightly different (almost exclusively expanded?) error message

I confirmed by repeatedly adding and removing that from the PATH that the presence of img_sdl2 in the "ignored" section depends on that, and that the expanded error text appears or disappears depending on if it could find SDL2 or not.

Now, the glew dependency should have a folder right next to it (share\glew\bin). What happens if you add that too?

Aha!

So, on Windows, it can be "solved" by prepending %AppData%\Python\share\glew\bin;%AppData%\Python\share\sdl2\bin; to PATH:

cmd /C "PATH=%AppData%\Python\share\glew\bin;%AppData%\Python\share\sdl2\bin;%PATH% && python3 -c ^"from kivy.core.window._window_sdl2 import _WindowSDL2Storage^""

But unfortunately this is not a solution per se

How ARE the pip-installed-python-libraries supposed to make their way into the PATH which they must be in to function? (A reboot was insufficient)

That was just a clue for me to find out whether the libraries are actually blocked or not. Good thing they aren't.

As said above (point 2.), you can see that if you open the __init__.py in site-packages\kivy\deps\..., but that should work out of the box. Now I need to find a way to break mine exactly like in your case. :smile:

Is this of any use?

Well,

some further testing reveals that it functions correctly if BOTH kivy.deps.glew AND kivy.deps.sdl2 are installed in Administrator mode.

I think the problem lies with too much being hardcoded into site-packages\kivy\deps\*\__init__.py

I wonder if there's a more canonical way to add DLLs from Pip packages into the PATH...?

Good question, but I don't know how the team arrived at their current solution. At least we could narrow it down now, so that's a step forward.

By the way, are you familiar with virtualenv. I normally use those and rarely have problems. So for now you could do (admin):

py -m pip install virtualenv

Normal user account (.venv is my preferred name of the directory of the virtualenv, change as you like):

py -m virtualenv .venv
.venv\Scripts\activate
python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew
python -m pip install kivy

optionally add: python -m pip install kivy.deps.gstreamer

Hope I got that all right.

I 've got same issue and I solve it and my solution is not a good one. I copy all dlls (share/sdl2 share/angle share/glew share/gstreamer) in a repository and I add this repository to path variable.

I installed kivy using admin right (https://kivy.org/docs/installation/installation-windows.html) and i tried to run using user right (user laurent )then error happens : [CRITICAL] [Window ] Unable to find any valuable Window provider.
sdl2 - ImportError: DLL load failed: The specified module could not be found.

Copying all dlls in new folder solves issues. My question is then How can I install kivy to run kivy with user privilege ?

PS sorry I 'm not good in english and python

By the way, are you familiar with virtualenv. I normally use those and rarely have problems. So for now you could do (admin):

py -m pip install virtualenv

Normal user account (.venv is my preferred name of the directory of the virtualenv, change as you like):

py -m virtualenv .venv
.venv\Scripts\activate
python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew
python -m pip install kivy

I tried using virtualenv and it did not work. I still got a similar error. I also added C:\Program Files\Python37\share\sdl2\bin and C:\Program Files\Python37\share\angle\bin to my PATH already. And I did what I think @LaurentBerger did, copy those two files into another directory, and then add that directory to the path. Using virtualenv with the two PATH options did not work for me as well.

I'm using python 3.7 so I installed kivy.deps.angle instead of kivy.deps.glew

On this issue, i've seen mixing libraries architectures (Python in 64 bits, SDL2 in 32 bits), so that's a first stop. And yes, if you mixed the arch, the libraries won't be used at all and Kivy won't work.
Installation of SDL2 via kivy.deps.sdl2 should works.

I am using python 3.7 and i am getting this error. kivy version is 1.10.1
how should i resolve it

same here python 3.7 , kivy version is 1.10.1 and tried all ways to load the DLL but shows no mercy.

Please see https://github.com/kivy/kivy/issues/6342.

This Solve My Problem Which is The same one you Had
Hope this will help You

I had the same issue. This video may help those who are visual! https://youtu.be/gt-qndBYrCQ

Had many issues, but managed to work them out. Here's what I learned (using PyCharm):
1) You can't install Kivy on Python 3.8. If you have 3.8, go back to 3.7.
2) I installed all of the packages that someone else posted a picture of. I'll post mine here. Go to your project interpreter and hit the "+" button to add them all. They should successfully install.


3) Was getting the window sdl2 error. Watched this short video (https://www.youtube.com/watch?v=e_jv8KsYBrs&t=212s) (may God bless this person) and changed my paths in my system environment.
4) I then reinstalled the dependencies from the Kivy website -- AND IT WORKED!!!

Hope this helps someone!!!!

By the way, are you familiar with virtualenv. I normally use those and rarely have problems. So for now you could do (admin):

py -m pip install virtualenv

Normal user account (.venv is my preferred name of the directory of the virtualenv, change as you like):

py -m virtualenv .venv
.venv\Scripts\activate
python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew
python -m pip install kivy

I tried using virtualenv and it did not work. I still got a similar error. I also added C:\Program Files\Python37\share\sdl2\bin and C:\Program Files\Python37\share\angle\bin to my PATH already. And I did what I think @LaurentBerger did, copy those two files into another directory, and then add that directory to the path. Using virtualenv with the two PATH options did not work for me as well.

I'm using python 3.7 so I installed kivy.deps.angle instead of kivy.deps.glew

Try to manually copy glew,sdl2 folders and __init__.py from ../site-packages/kivy_deps to ../site-packages/kivy/deps.
It worked for me
