how to import library for python

[ua4ever]

I want to install pip module and pyrogram module for my project in flutter

[Mellak]

Hello, I have the same issue, have you find the solution ?

[godilite]

Any solution yet?

[danyaYatsik]

@srplab , could u help us?

[MariaNabil]

Same issue , is there any solution ?

[sahilcool-nsut]

Still no solution?

[srplab]

1. Install the package in the host environment using pip, for example "pip install markdown"
2. Compress the entire directory of the package into a zip file, and put it in starfiles folder

3. set python import path, for example,

   String assetsPath = await Starflut.getAssetsPath(); int Platform = await Starflut.getPlatform(); if( Platform == Starflut.ANDROID){ await Starflut.copyFileFromAssets("markdown.zip", "flutter_assets/starfiles","flutter_assets/starfiles"); } python.call("import", ["sys"]);

   StarObjectClass pythonSys = await python.getValue("sys"); StarObjectClass pythonPath = await pythonSys.getValue("path"); pythonPath.call("insert",[0,assetsPath+"/flutter_assets/starfiles/markdown.zip"]);

   python.call("import", ["markdown"]); StarObjectClass markdown = await python.getValue("markdown"); String v = await markdown.call("markdown",["## hell-world"]);

Copying your same code, i've having some issues. 1) First issue was related to some importlib_metadata module. So i thought i'll import it the sameway as we are doing the markdown import. 2) After that, i got some error regarding " No module named '_csv' ". I couldn't think of a potential fix for this, as this seems to be an inbuilt file which should have been installed with python, and can't be installed manually.

[srplab]

add _csv.cpython-39.so to the project

[sahilcool-nsut]

Where am i supposed to find this .so file? Will it be available in my system if im on Windows? I cant find any place on the internet to download this

I appreciate your help, but im still facing problems in the installation. Now, it says it cant find the module 'math'. I think the problem is that it cant find the inbuilt cpython files to compile. If possible, can you provide a WORKING example, with appropriate starflut function calls, so that we can succesfully import external libraries?

感谢您的帮助，但我仍然在安装过程中遇到问题。 现在，它说找不到模块“数学”。 我认为问题是找不到内置的cpython文件进行编译。 如果可能，您是否可以提供一个带有适当starflut函数调用的WORKING示例，以便我们可以成功导入外部库？

[srplab]

The missing python module can be found in https://github.com/srplab/starcore_for_android/raw/master/android.python.3.9.0.zip. Add them to the project

[Hong822]

@srplab: Hi I'm trying to import 'requests' packages but keep failing. What I did is,

1. Install python3.9.0

2. download 'requests' by pip install requests.

3. Compress the downloaded package into a zip. (Attached) requests.zip

4. Paste the file in starfiles folder

5. I added the following code as you instructed. `String assetsPath = await Starflut.getAssetsPath(); int Platform = await Starflut.getPlatform(); if( Platform == Starflut.ANDROID){ await Starflut.copyFileFromAssets("requests.zip", "flutter_assets/starfiles","flutter_assets/starfiles"); }

   python.call("import", ["sys"]);

   StarObjectClass pythonSys = await python.getValue("sys"); StarObjectClass pythonPath = await pythonSys.getValue("path"); pythonPath.call("insert",[0,assetsPath+"/flutter_assets/starfiles/requests.zip"]); python.call("import", ["requests"]);`

6. However I still face the error message below. I think Starflut still don't recognize the package.

I/flutter (13614): -1 4 ModuleNotFoundError: No module named 'requests' 0

Could you guide me how to solve this?

Thank you.

[srplab]

1. compress request to zip with folder name
2. requests depends on other python packages, and package them together， See attached file
3. Add the native libraries used below to the project await Starflut.copyFileFromAssetsEx("_struct.cpython-39.so", LibraryPath,null,false); await Starflut.copyFileFromAssetsEx("binascii.cpython-39.so", LibraryPath,null,false); await Starflut.copyFileFromAssetsEx("math.cpython-39.so", LibraryPath,null,false); await Starflut.copyFileFromAssetsEx("_random.cpython-39.so", LibraryPath,null,false); await Starflut.copyFileFromAssetsEx("_sha512.cpython-39.so", LibraryPath,null,false); await Starflut.copyFileFromAssetsEx("_socket.cpython-39.so", LibraryPath,null,false); await Starflut.copyFileFromAssetsEx("_ssl.cpython-39.so", LibraryPath,null,false); await Starflut.copyFileFromAssetsEx("select.cpython-39.so", LibraryPath,null,false); await Starflut.copyFileFromAssetsEx("array.cpython-39.so", LibraryPath,null,false); await Starflut.copyFileFromAssetsEx("_hashlib.cpython-39.so", LibraryPath,null,false); await Starflut.copyFileFromAssetsEx("_blake2.cpython-39.so", LibraryPath,null,false);

4. Before initializing python, set environment variables String docPath = await Starflut.getDocumentPath(); await Starflut.setEnv("TMPDIR",docPath);

   Currently need to modify StarflutPlugin.java as follows(In the next version of starflut, these codes will be merged)： case "starcore_getPlatform" :{ result.success((int)0); } break; case "starcore_setEnv" :{ ArrayList

Hi, i´m doing exactly what you have described but it doesn´t work, also i cant find StarflutPlugin.java so i cant modify it.Here is my debug log:

How to import sth like numpy to the package to use in python code? something like adding the pip installed fikes to site-packages of your python.zip causing this Error for me:

D/starcore(14083): import encodings failed.... D/starcore(14083): ModuleNotFoundError("No module named 'encodings'",) D/starcore(14083): /data/data/com.example.flutter_ocr_test/files:/data/data/com.example.flutter_ocr_test/files/python3.6.zip:/data/data/com.example.flutter_ocr_test/files/libs64:/data/data/com.googlecode.pythonforandroid/files:/sdcard/com.googlecode.pythonforandroid/extras/python:/data/data/com.googlecode.pythonforandroid/files/python/lib/python2.6/lib-dynload:/data/data/com.googlecode.pythonforandroid/files/python/lib/python2.6:/data/data/com.googlecode.pythonforandroid/files/python/lib/python26.zip D/starcore(14083): Py_Initialize: unable to load the file system codec
