@silm,

Apparently it looks like configuration issue on your end where it may not find Aspose.Cells for Python library/jar. So, you should sort it out accordingly. We will also evaluate your issue soon.

Thanks. I dont know where can i refer to get the solution for this. I only install AsposeCells from PIP and dont make any setting in my PC. Please help me solve this issue, thank you

@silm
Please provide us more details: package tool, package script etc. We will investigate the issue.

i’m using VSCode for implementing my script. I use AsposeCells for converting from HTML to Excel with Jpype 1.2.1 . The version of AsposeCell is 22.10.0

@silm
How do you package the scripts to exe?

i’ve used PyInstaller or Auto-py-to-exe but got this error also.

I traced in api.py file and saw that com.aspose.cell wasnt imported, but i can run my script without error. Please help me. Thanks a lot

The issue should be caused by the below code in “__init__.py”

__cells_jar_dir__ = os.path.dirname(__file__)

addClassPath(os.path.join(__cells_jar_dir__, "lib", "aspose-cells-22.10.jar"))

addClassPath(os.path.join(__cells_jar_dir__, "lib", "bcprov-jdk15on-160.jar"))

addClassPath(os.path.join(__cells_jar_dir__, "lib", "bcpkix-jdk15on-1.60.jar"))

addClassPath(os.path.join(__cells_jar_dir__, "lib", "JavaClassBridge.jar"))

The jars cannot be load by JPype correctly when packaging in exe. Please trace “__file__” and “__cells_jar_dir__”, and check if the jars exist in the path.

@silm
Please check them in unpackged tmp folder when running the exe. Please trace the variable values of __file__ and __cells_jar_dir__ when running the exe.

I tried to debug with file and cells_jar_dir . The exe file was packeged so i dont know where can i get these information that you want.

How can i do it? Please help us or can you give me some way to contact by Teams or Skype to solve it faster?

I’m a new begginer in Python and Aspose also. Thank you

@silm
The exe generated by directly using pyinstaller example.py will indeed have the problems you mentioned. Assuming example.py is your application.
Below is my solution:

  1. run pyinstaller example.py, there will be an example.spec file generated.
  2. edit example.spec like below:
mydatas = [('./aspose-cells-22.11.jar', '.'),
				('./bcprov-jdk15on-160.jar', '.'),
				('./bcpkix-jdk15on-1.60.jar', '.'),
				('./JavaClassBridge.jar', '.') ]

a = Analysis(
    ['example.py'],
    pathex=[],
    binaries=[],
    datas=mydatas,
    hiddenimports=[],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=block_cipher,
    noarchive=False,
)
  1. copy the jars (in asposecells/lib folder where installed) to the same folder of example.py,
  2. add the following code to the beginning of example.py
import os

from jpype import *

__cells_jar_dir__ = os.path.dirname(__file__)

addClassPath(os.path.join(__cells_jar_dir__, "aspose-cells-22.11.jar"))

addClassPath(os.path.join(__cells_jar_dir__, "bcprov-jdk15on-160.jar"))

addClassPath(os.path.join(__cells_jar_dir__, "bcpkix-jdk15on-1.60.jar"))

addClassPath(os.path.join(__cells_jar_dir__, "JavaClassBridge.jar"))
  1. edit __init__.py (in asposecellsfolder where installed) of aspose as below:
from __future__ import absolute_import

__all__ = ['api']
  1. run pyinstaller example.spec
    Now your example.exe should work well.

@silm,

We are sorry that the suggested solution does not work on your end. We will look into it further and get back to you soon.

Thanks a lot for your support. Hoping the solution from you soon. It looks like the lib havent added into exe package. When i run into Atempping ‘datas’ into exe , notthing happen and it’s up. Thanks again Aspose Team.

@silm
Please change your jar name to aspose-cells-22.10.jar in below 2 places:
mydatas = [('./aspose-cells-22.10.jar', '.'),

addClassPath(os.path.join(__cells_jar_dir__, "aspose-cells-22.10.jar"))
