Installing Python Modules

Skip to comments   Jump To End

I tried following the instructions at https://synthiam.com/Support/python-api/add-custom-python-modules but ran into issues so I uninstalled ARC and reinstalled. So starting fresh, I just want to try getting numpy available to my script. I created a new python script in ARC as follows: import sys print(sys.version) print(sys.executable) import numpy

I get the following output:

The import and calls to SYS work (even though executable is empty for some reason), but I would expect to see something along the line of "module not found" for the numpy import. Why am I seeing the above error and what does it mean here?

Thanks Oisin

I did but your webpage squashed it all up into the following line:  import sys print(sys.version) print(sys.executable) import numpy

Further to this I note that the command "add_dll_directory" only came in in python 3.8, so why do I see it here in ARC's version 3.4?

It seems like you're encountering an issue with importing the numpy module in ARC's Python scripting environment. Let's address your concerns step by step:

  1. Python Version in ARC: ARC uses a specific version of Python that might not support all the latest features or modules. The add_dll_directory function is indeed available from Python 3.8 onwards, and if ARC is using Python 3.4, this function won't be available.

  2. Installing Python Modules in ARC: To use external Python modules like numpy in ARC, you need to ensure that the module is installed in the Python environment that ARC uses. Here’s a general approach to do that:

    • Locate ARC's Python Environment: You need to find out where ARC's Python environment is located. This can sometimes be tricky if the sys.executable is not providing the path.
    • Install the Module: Once you have the path, you can use a command prompt to navigate to that directory and use pip to install numpy. For example: 
      cd path\to\arc\python
pip install numpy

  3. Troubleshooting:

    • Check Python Path: If sys.executable is empty, it might indicate an issue with how ARC is configured to use Python. Ensure that ARC is correctly set up to use its Python environment.
    • Error Messages: If you encounter specific error messages when trying to import numpy, please share them here. They can provide more insight into what might be going wrong.

  4. Alternative Solutions:

    • Use JavaScript: If Python is proving too problematic, consider using JavaScript for your scripting needs in ARC. JavaScript is well-supported and might offer a smoother experience.

If you continue to face issues, please provide any error messages or additional details, and I'll be happy to assist further!

So I think I have the following issue happening: I try import numpy and it tells me "No module named 'numpy'". All good.

I run the following install: pip install numpy --target="C:\Users\oisin\Documents\ARC\Python Modules"

It installs numpy version 2.3.1 in the above directory. When I try import it in a script I get "invalid syntax". I am assuming that this is because ARC uses Python 3.4.1 for which I would need an earlier version of numpy?

So I deleted the files from "Python Modules" and tried the following install: pip install numpy==1.16.0 --target="C:\Users\oisin\Documents\ARC\Python Modules" But this generates errors and does not install. This might be because I have Python 3.10.10 installed on my machine. Does all this make sense and if so do I have to downgrade my machine to 3.4.1 and then run the installs?
