unity-python's Issues

An error happened when I used 'xlrd' to read excel file

I'm sorry to disturb you again and thank you first. There are codes that I wrote to read the excel file:

var engine = global::UnityPython.CreateEngine(); 
var scope = engine.CreateScope();
var paths = engine.GetSearchPaths();
paths.Add(UnityEngine.Application.dataPath + "/UsePythonInUnity/Lib");
engine.SetSearchPaths(paths);
string code = "";
code += "import xlrd" + "\n";
code += "file = 'test.xlsx'" + "\n";
code += "file = file.decode('utf-8')" + "\n";
code += "filename = str(file)" + "\n";
code += "excelfile = xlrd.open_workbook(filename)" + "\n";
code += "sheet1 = excelfile.sheet_by_index(1)" + "\n";
code += "row = sheet1.row_values(1)" + "\n";
code += "line = ''.join('%s' %id for id in row)" + "\n";
var source = engine.CreateScriptSourceFromString(code);
string result = scope.GetVariable<string>("line");

The error info：
Microsoft.Scripting.ArgumentTypeException: expected str, got bytes

I tried to cut down my python codes line by line, and I found the same error happened even if I just used first five lines python codes. But if I just used first four lines python codes, no error would happen. Since I thought the error happened in fifth line python code:
code += "excelfile = xlrd.open_workbook(filename)" + "\n";

But I have checked the type of the variable 'filename' by using 'type()' function, so I can confirm that the type of variable 'filename' is 'str'. Consequently, this error confusing me a lot and I have no idea about the cause of this error. I wuold appreciate it if you can provide some clues. Thanks again!

can this use python3.x ？

Make the integration work "out of the box"

Right now, the Python standard library is not included in the build. The reason for this is because the IronPython library only exposes a method for loading python libraries from the disk (as far as I know). We can accomplish this by putting the Python library in the StreamingAssets folder, but this is a security problem since the library can be trivially edited by any user to do whatever they might want. This is the main reason for why the included python library in unity-python doesn't work in builds right out of the box.

Several issues are affected by this problem:

• The additional steps are not very clear and make the library difficult to use since it doesn't work "out of the box" #10
• It's not clear how to add additional libraries to the project #4, #8
• Adding additional libraries might require the addition of more .NET DLLs to the project in order for the build to work #11

I did find an approach that looks appealing recently... It might be possible to compile the Python libraries into DLLs.

If this works the way I think it does, then I can make an interface for installing Python libraries which fetches the package from pip, compiles it into a DLL, and then adds it to your project. This would fix all of the aforementioned issues.

However, it would be best to keep in mind that Python 2 is being deprecated on January 1st, 2020 with pip to follow suit shortly after. I have never tested the library as it stands today with Python 3 (and I don't have any reason to believe it will work). So, perhaps this work will have to wait until the library is ported to work with Python 3.

using cv2 module occured "SyntaxErrorException: unexpected indent" Error.

Hi,Thank you for this project.
Here is the issue:
I want to use opencv - python to do a little test in unity (to read a texture pixel debug),And I refer to the issue which you answered.

I move the "..Python/Lib/site-packages/cv2" file to my "Assets/Python/lib" Unity Folder.And the picture "is.png" is also under the "Assets/Python/lib" folder too. So I run my code which is worked good on PC python environment. And I got this :"SyntaxErrorException: unexpected indent".

So now I can't to deal with it. So much appreciate if you can help. 👍

can't run a python script and catch the output

I tried to run it and I get no output. There is no documentation about how to retrieve the output of a python script.

Once you execute the script with source.Execute(scope);, how do you get the output?

The type initializer for 'CodecsInfo' threw an exception on Build

I runned ironpython succesfully on editor runtime. I built succesfully MACOSX from iMac and when I run the game, I got the error in title.

HelloWorld works but my code doesn't work. My code works on Editor mode but not in build runtime :)

I have tried to change API Compatibility Level.
I have installed from unitypackage.

The error comes in this line :
source.Execute(scope);

Update IronPython?

I seen IronPython 3 supports NET 4.5 while IronPython 2 still supports NET 2.0, I think the latest version is 2.7.7 or 2.7.8?

Update IronPython to 2.7.9

Update the version of IronPython used by unity-python to 2.7.9, which was released on 2018-10-09.

UnauthorisedAccessException in Android

Thank you for sharing this package. it works well on editor, but when i built it for android and run application in android device it gives.
"UnauthorisedAccessException: Access to path "/" is denied."

it is strange because file is present at this path and i can read the file via readalltext. but it gives me error when i pass the same file path to "ExecuteFile()"

Thanks

After searching for solution in IronPython, there's a common answer that the option has to be enabled:
var options = new Dictionary<string, object>(); options["Frames"] = true; var engine = Python.CreateEngine(options);
But! With: global::UnityPython.CreateEngine(); > CreateEngine cannot get options argument.
Apparently this is fixed in IronPython 2.7.8 - Frames are enabled by default...

Any quick fix?

System.NotSupportedException: Encoding 37 data could not be found. (Error on Build)

This plugin works just fine in the editor, but I get a werid error on the build. The way I'm starting the script goes something like this:

var engine = UnityPython.CreateEngine();
var paths = engine.GetSearchPaths();
// I've copeid the Python folder to StreamingAssets for the libraries to work
paths.Add(Application.streamingAssetsPath + "/Python/Lib");
engine.SetSearchPaths(paths);

try
{
    var source = engine.CreateScriptSourceFromFile(scriptPath);
    source.Compile();
    // script here is a dynamic variable
    script = engine.Runtime.UseFile(scriptPath); // this is where it stops working
    script.GameManager = this;
    script.start();
}
catch (Exception e)
{
    Debug.Log("Error: " + e);
}

The python script I am using uses the threading and Queue libraries, if that helps.

Full Error:

I read comments from some of the previous issues, and tried to import numpy module.
Version of Unity 2018.4, Windows
Here are steps that I took:

1. Install Anaconda, & install virtual environment with python 2.7
2. Install numpy in python 2.7 environment
3. Find the path of python 2.7 libs and add line paths.Add('path_to_lib\\lib'); in examples/pythonlibrary
4. Step 3 gave error and I deleted the line added in step 3
5. I tried copy related folders in libs (all mkl folders & folders with numpy in it) to Python/Libs in the project

Problem encountered:
Both 3 and 4 gives same error:

ImportException: 

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
Here is how to proceed:
- If you're working with a numpy git repository, try `git clean -xdf`
  (removes all files not under version control) and rebuild numpy.
- If you are simply trying to use the numpy version that you have installed:
  your installation is broken - please reinstall numpy.
- If you have already reinstalled and that did not fix the problem, then:
  1. Check that you are using the Python you expect (you're using None),
     and that you have no directories in your PATH or PYTHONPATH that can
     interfere with the Python and numpy versions you're trying to use.
  2. If (1) looks fine, you can open a new issue at
     https://github.com/numpy/numpy/issues.  Please include details on:
     - how you installed Python
     - how you installed numpy
     - your operating system
     - whether or not you have multiple versions of Python installed
     - if you built from source, your compiler versions and ideally a build log

     Note: this error has many possible causes, so please don't comment on
     an existing issue about this - open a new one instead.

Original error was: cannot import _multiarray_umath from numpy.core

"The dll is not allowed to be included or could not be found." exception when building project

Hi sir,
Thanks for sharing this awesome library, it works smoothly in the editor!

However, when I tried to build the project (PC standalone in this case), I got this error which I could not understand why. It said "ArgumentException: The Assembly PresentationFramework is referenced by IronPython.Wpf ('Assets/Libs/Python/IronPython.2.7.9/lib/net45/IronPython.Wpf.dll'). But the dll is not allowed to be included or could not be found.", but I have this .dll file in my Assets folder already.

I set the Scripting Runtime Version to ".NET 4.x Equivalent" and Api Compatibility Level to ".NET 4.x".
I also tried to import IronPython from official website but still got the same error. Could you help me with this problem?

socket.send() - expected str, got bytearray

We need a socket.send () method that takes a bytearray as its argument.

Hi, Thanks to Unity Python.

This time, I run a socket communication Python file made with general Python. I create a bytearray and send it. I tried several attempts to convert it to a string, but it all failed.

I've downloaded the IronPython source separately and tried to build it but it will not work with Unity.

Can you help me?

IronPython.dll But the dll is not allowed to be included or could not be found.

Unity Version: 2019.1.0f2
Unity Python 0.4.1

I got error when tried to build to WebGL.
I got an error with "ArgumentException: The Assembly Mono.Posix is referenced by IronPython ('Assets/Python/IronPython-2.7.9/IronPython.dll'). But the dll is not allowed to be included or could not be found."
