Error on import numba: module '_godot' has no attribute 'print_override' #238

thetoblin · 2020-09-28T08:08:28Z

I'm on Ubuntu 18.04, Godot 3.2.2 through standard 64-bit download.

I seem to be able to import python libraries by adding a path to where the python libraries are on disk in the Project Settings> General> Filesystem> Python Script> Path using the Godot editor.

I'm using conda, and I've added
/home/[username]/anaconda3/lib/python3.8;
/home/[username]/anaconda3/lib/python3.8/lib-dynload;/home/[username]/anaconda3/lib/python3.8/site-packages

which seems to make packages such as math, numpy, etc importable in Godot. When I try to import a package called numba however, I get the following error:

    if getattr(mod, val.__name__) is not val:
AttributeError: module '_godot' has no attribute 'print_override'

That the code refers to 'print_override' suggests to my mind that there might be many errors that is attempted to be printed, but it fails to do so because of the missing attribute of 'print_override'.

Does anyone have any ideas on what the problem could be? Since it works to import other libraries, such as numpy, there could be something specifically wrong with the numba library. Importing numba in a normal python script works however.

The text was updated successfully, but these errors were encountered:

_godot is a python module we provide that is imported when the Godot engine initialize godot-python plugin.
Hence it shouldn't be imported from python code (but importing it shouldn't be a problem in theory).

The stacktrace suggests numba is doing some magic with the builtins, I guess this is clashing with what godot-python is doing when capturing stdout/stderr.

Capturing stdout/stderr used to involve the replacement of the builtins print and print_stacktrace:

godot-python/pythonscript/_godot_io.pxi

Lines 135 to 150 in 8c36c9b

    
           def enable_capture_io_streams(): 
        
               # flush existing buffer 
        
               sys.stdout.flush() 
        
               sys.stderr.flush() 
        
               # make stdout and stderr the custom iostream defined above 
        
               sys.stdout = GodotIO.get_godot_stdout_io() 
        
               sys.stderr = GodotIO.get_godot_stderr_io() 
        
               # override python print function 
        
               GodotIO._builtin_print = builtins.print 
        
               builtins.print = GodotIO.print_override 
        
               # override traceback.print_exception 
        
               GodotIO._traceback_print_exception = traceback.print_exception 
        
               traceback.print_exception = GodotIO.print_exception_override

However this has changed: now we only replace sys.stdout/stderr. I guess this should fix your current issue.

Can you try with the latest master of Godot-Python ?

thetoblin · 2020-09-28T08:37:40Z

Using the "latest master of Godot-Python" means that I have to compile Godot from source, right? (Sorry to ask). So I have to compile Godot from source, and then somehow include Godot-Python.

correct

So I have to compile Godot from source

you don't need to compile Godot, Godot-Python is a module loaded from the gdnative interface (so basically Godot loads a shared library that initialize the godot-python module)

tl,dr: you can do:

$ python -m venv venv
$ . ./venv/bin/activate
$ pip install -r requirements.txt
$ scons platform=x11-64 example

This should compile godot-python, install it in examples/pong and run this example project.
From there you should be able to copy what is done in the examples/pong to install the compiled godot-python into your own project (basically you should just have to copy or symlink the build/dist/addons/ folder into your project)

thetoblin · 2020-09-29T07:12:19Z

Thanks for replying even to my noob questions! =)

After running

$ python -m venv venv
$ . ./venv/bin/activate

I cloned Godot-Python using git to disc. I then ran pip install -r requirements.txt, which seems to have worked. I then tried to run scons platform=x11-64 example, but it failed due to ``godot_headers/api.json' not found. I therefore went to the Godot headers and cloned it into the godot_headers` folder.

touilleMan · 2020-09-29T07:29:51Z

you miss the godot_headers submodule, to fetch it you should do:

$ git submodule init
$ git submodule update

Received an error again, so I tried to restart the terminal and do everything from scratch. I got an error again. Here is all the terminal outputs:

Looks like you stumble on something new !
I couldn't reproduce your issue on my computer (Pop!_OS 20.04 LTS) with a clean git checkout of the project and a new virtualenv 😢

The compilation part of your scons example command seems surprisingly short (it displays only the compilation of _godot.pyx), are you sure you're working from a clean git repo with no previous build directory ?

For instance here is the build log I got (ignore the final WARNINGS/ERRORS, they are expected when closing the game):

=) we'll see. Probably my fault at some level.

are you sure you're working from a clean git repo with no previous build directory ?

No, I'm not sure. I barely use git (as you may have noticed). How do I find out if it is a clean git repo? Should I delete everything in the Godot-Python folder and clone it again? Or is there some meta-considerations to take care of as well? I will try to google to see if I can figure it out.

thetoblin · 2020-09-29T09:15:25Z

I removed the godot-python repo and cloned it from git again. Then I retraced all the steps. It seems to have worked (see below). I will go figure what the next step is from your comment above. Will return with questions and/or results =)

This should compile godot-python, install it in examples/pong and run this example project.
From there you should be able to copy what is done in the examples/pong to install the compiled godot-python into your own project (basically you should just have to copy or symlink the build/dist/addons/ folder into your project)

So I have created a new Godot project, and then copied the build/dist/addons/ from the compiled godot-python git repo to the main folder of the new Godot project. The file system now looks like this in Godot:

Should I now expect to be able to create .py scripts from Godot? (Because I cannot)

Or should I simply create the python scripts manually using a text editor external to the Godot editor?

touilleMan · 2020-09-29T09:59:56Z

The "language" selector should provide a Python option

You are most likely missing the pythonscript.gdnlib file that should be at the root of your project (this tells Godot about the godot-python plugin and how to load it)

On top of that, your project.godot file should contain:

[gdnative]

singletons=[ "res://pythonscript.gdnlib" ]

this is something you can add by hand, or use the Project -> Project Settings -> GDNative menu from within Godot to enable pythonscript.gdnlib

Note you must then restart Godot before being able to use Python from within Godot

thetoblin · 2020-09-29T10:34:56Z

I copied the pythonscript.gdnlib from another project where I had installed godot-python through the assetlib into the new Godot project with compiled godot-python. Somehow this seems to have added the singletons information, since when I went to Project -> Project Settings -> GDNative the entry of singletons=[ "res://pythonscript.gdnlib" ] was already present.

Now it works to create python scripts in the Godot Editor, and after adding global paths to my conda installation in the Project Settings > Python Script > Path (which I know will make the project unable to export, I'll solve that later), I seem to be able to import some python modules such as math.

I cannot however import other python modules such as numpy and numba. After thinking, I'm postulating that this has to do with the compilation of godot-python we did through venv, since when I try to import those modules through a venv python shell does not work.

My hypothesized solution is to recompile godot-python but with the added modules of numpy and numba in the requirements.txt file, as per the directions here: https://docs.python.org/3/tutorial/venv.html as such:

numpy==1.19.1
numba==0.51.2

I will return with results or questions. If my thinking is wrong, please feel free to intervene =)

thetoblin · 2020-09-29T11:22:18Z

Adding numpy and numba to requirements.txt does not appear to have worked. Trying to import them in a python script in the Godot project still gives the ModuleNotFoundError: No module named [numpy/numba]. I've also tried running the Godot project from a venv shell where numpy and numba are installed, but without success.

Note that in retracing the steps (where I updated the requirements.txt) I did not create a new Godot project. Instead I simply replaced the addons folder from the new compiled godot-python. I don't see how this should affect anything, but I mention it in case it might be relevant.

Question
So, the question now is: how do I import python modules (numba, numpy) in the godot project with the godot-python master addon?

Summary of steps
Below is a summary of the steps I took:

# clone godot-python from git
$ git clone https://github.com/touilleMan/godot-python.git

# add desired python modules to the requirements.txt file in the clone folder. Examples:
numpy==1.19.1
numba==0.51.2

# from within the git-cloned godot-python main folder, run:
$ git submodule init
$ git submodule update
$ python -m venv venv
$ . ./venv/bin/activate
$ pip install -r requirements.txt
$ scons platform=x11-64 example

# create new godot project and copy the pythonscript.gdnlib file from another working godot-python project into the main folder of the new project. The file can for example be acquired from a godot-python godot project where godot-python has been installed through the AssetLib.

# Make sure that 
[gdnative]
singletons=[ "res://pythonscript.gdnlib" ]
# is in the Project -> Project Settings -> GDNative menu. This is to enable pythonscript.gdnlib

# Add the python module import path to the Godot project under Project Settings > Python Script > Path. The python path to use can be found by starting a python shell and running:
import sys
print(sys.path)

# This should give something like this, which should be added to the Python Script > Path. Note that adding absolute paths breaks the project export. Another method to enable python module imports needs to be used:
/home/tobka/anaconda3/lib/python38.zip;/home/tobka/anaconda3/lib/python3.8;/home/tobka/anaconda3/lib/python3.8/lib-dynload;/home/tobka/godot-python/venv/lib/python3.8/site-packages

thetoblin · 2020-10-05T11:03:00Z

Ok, so the problem of how to import modules was solved by going to the [project dir]/addons/pythonscript/ and running

./x11-64/bin/python3 -m ensurepip
./x11-64/bin/python3 -m pip install numba # where numba is a package name.

This allowed me to import numba and other installed packages in godot-python.
