Error: Kivy- Unable to find a valuable window provider

[markR]

After  using pyinstaller to create a bundled app, running it gives above error. 

Search results say to: pip install docutils pygments  pypiwin32 kivy.deps.sdl2 kivy.deps.glew .

Elliot, as you have been shepparding me on this install creation; would you recommend above as a first step or should i look at something else?

[Elliot Garbus]

Are you running pysintaller from the activated venv?  Does the program run properly from the activated venv?

 

If not, activate the venv, and install kivy per the directions on the web site.

There is a pyinstaller folder in my site packages in the environment i am working in. The environment was activated when i attempted to use pyinstaller. That makes me want to say -Yes. 

The program runs fine in the venv.

I will make another attempt at kivy install and let you know. What confuses me is there exists folders already for kivy, all the _deps, garden, and dist_info.

[markR]

So I made sure environment was activated.

I uninstalled kivy

I reinstalled kivy: python -m pip install "kivy[base]" kivy_examples- successful

I uninstalled: docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew; 

I reinstalled: python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew; -successful

I ran pyinstaller : pyinstaller Bovine25.py

Still same error!

Gleening pyinstaller output i included below questionable comments. 

Do you see any show stoppers?

I noticed a couple of duplicates which may or may not mean anything.

Uninstall kivy

 

Then install kivy… it will install the appropriate dependencies:

python -m pip install "kivy[base]" kivy_examples

 

and give it a try.

 

In my experience the most useful errors are the errors in the kivy log file.

After following exact sequence as listed above I continue to get the same error.

Is it important to note that while pyinstaller was doing its thing- a blank kivy screen popped up for a split second but immediately went away?

I have looked around for this kivy log file but I am not experienced enough to locate it. You might direct me on some there.

thanks

[Elliot Garbus]

Wow that is frustrating.

 

Here is the location of the kivy log files: C:\Users\YourUserNane\.kivy\logs

It is normal for the Window to pop up and close when pyinstaller is running.

 

Looking at the top of the spec file you will see:

 

a = Analysis(['../main.py'],
             pathex=[],
             binaries=[],
             datas=[('../*.kv', '.'),
                    ('../Images/*.png', './Images')],

Is main.py the name of your main python code?  If not change the name in your spec file.

The spec file uses relative paths and assumes the specfile is in  a directory under the project directory.

 

I usually have a structure like this:

MYPROJECT – directory

    MYProjectDist

        W10.spec – the spec file

    Images – Directory for Images

    main.py – python and kv files are under MYPROJECT

    my.kv

    other.py

In my environment folder the python app is named Bovine25 which is indicated as a PY file.

In the dist folder pyinstaller created a folder called Bovine25

    in the Bovine25 folder the application name is Bovine25- the one with the python icon

Here is my .spec

I suspect we have a directories path issue…

C:\Users\marka\PythonEnv\Bovine25env\dist\Bovine25\kivy_install\data\glsl\default.png

Have you nested virtual environments?

 

FWIW here is the directory structure of a program I’m working on:

The full project path:  C:\Users\ellio\PycharmProjects\ME-Surgeon

Note below the venv is a subdirectory of the project.  It does not need to be.

 

As you can see, I put the spec files in ME-Dist. I switch to that directory to run pyinstaller.

The PythonEnv folder is not an environment. It is where I will store all the different environments I might create in the future as well. Bovine25env is a venv. So looking at what you do you separate the build and dist folders from the venv even though pyinstaller creates them there.

So my thoughts are to create a project folder above the venv(Bovine25env) folder and move the build and dist files into it. Is that what you are recommending? 

[Elliot Garbus]

Because I put the spec file in ME-Dist, and cd to that directory to run pyinstaller, that is where the build and dist directories are created.

I would not recommend putting your code files in the venv directory.  Make your venv a subdirectory of the project (as below) or just another directory.  I put my code up on GitHub, but not the venv.

Ok, so based on above, I just started fresh and created a new project folder, created its own venv folder(python -m venv CattleMgt-venv), etc. as below and copied my .py and data files over:

CattleMgt

    CattleMgt-dist

    CattleMgt-venv

    Bovine25.py

    -------------.py

    ----------.py

    -------.db

I cd to venv folder

I activated this environment

I installed kivy per docs

I tried to run pyinstaller but it's name was not recognized

I uninstalled pyinstaller from the python39\site_packages

I reinstalled pyinstaller

I cd to my CattleMgt-dist folder

I ran pyinstaller Bovine25.py but it could not find Bovine25.py

I cd back CattleMgt folder, ran pyinstaller and it ran as it has been. created a build and dist folder in CattleMgt folder.

Ran from cmd prompt and got the same error.

So if getting the build and dist folders to be created in my CattleMgt-dist folder is the key; how do i do that without moving my .py files into the same folder?

From what I can figure out, the spec file is not created until pyinstaller runs so i can not pre-put that in anyfolder. 

LOST.

[Elliot Garbus]

You might want to find a resource on venv.  I’m at a loss to suggest something useful.

 

I never cd into the venv.

I activate it from the working directory.  I pip install from there.

 

I would put the spec file into CattleMgt-dist

Cd in CattleMgt-dist

Pyinstaller yourspecfile.spec

 

You will need to change the path as appropriate in your spec file if you spec file is not in the same dir as your .py files.

[markR]

Thanks, I am not giving up yet.

Clarification on something you indicated above, I pyinstaller myApp.py not the .spec file. Do I need to be doing something different here?

[Elliot Garbus]

Run pyinstaller using the spec file!

>pyinstaller myspecfile.spec

Issue Resolved:

Do not ever assume you have a "simple" app and can just run pyinstaller against the .py and be off to the races- you will be off in the weeds.

To correct the initial issue of not having a windows provider; in the .spec file  I had to import sdl2 and glew. Also, not understanding why-just followed directions, and in coll(collect) added *{Tree(p) for p in (sdl2.dep_bins +glew.dep_bins)].

Following, it could not find my db even though it was in the folder. I thought it would find it like it did when running it out of environment. I had to add it in the datas=. What a arduous learning experience.

Thanks Elliot for getting me to think about the .spec file.

[Elliot Garbus]

Glad to hear you got it working!
