Isaac SIM 4.5 seems to have some vulnerabilities in the configuration environment, lacking some Python feature packages

I am using Isaac Sim 4.5, but I’ve encountered significant issues while configuring the environment. It’s different from previous versions. When I set it up in PyCharm, only some of the packages can be imported, while others remain missing.

When I use the “ScriptEditor,” all the packages can be found without any issues.

Previously, when I used Isaac Sim 4.0-4.2 (2023.1), I didn’t face these problems—I just pointed the Python environment to “python.sh,” and it worked fine.

However, after upgrading to Isaac Sim 4.5, this approach no longer works, and only some Python packages are accessible.
I’d like to know how to properly configure the environment in PyCharm, as it seems Isaac Sim 4.5 might have some bugs or issues.

I hope to receive some guidance and assistance

PyCharm is not officially supported. If you’ve successfully used it with Isaac Sim 4.2.0, could you please provide the detailed steps you followed?

@VickNV
Thank you for your response and assistance. I have indeed been using PyCharm consistently with Isaac 2023.1.1, Isaac Sim 4.1, and Isaac Sim 4.2, all in standalone mode.

First, I configured the environment. The image shows my Python environment setup, where I added python.sh to my Python environment for compilation. While some packages were missing (though most were present), I manually located and copied the missing ones into my Python project, then marked them as “Sources Root” using “Mark Directory as → Sources Root”.

However, after upgrading to Isaac Sim 4.5, this method no longer seems to work. Only a very small portion of the packages are usable—most are not.

Is there another way for me to edit the code? If PyCharm is no longer viable, does Isaac Sim 4.5 recommend a different Python editor? Or is there a detailed tutorial on how to properly configure the environment?

Would appreciate further guidance on resolving this!

I used “Visual Studio,” but I encountered some issues. At the same time, I noticed that some people on the forum had the same questions as me.

First, I tried the “Isaac Sim VS Code” method: My steps were “IsaacSim → Windows → VSCode.” I opened “VSCode” ,It ran successfully and created objects without any issues.

However, when I do not use “IsaacSim VS Code Edition” and instead just use “Visual Studio Code,” after setting up the environment, it fails to import the required packages.

However, after I added:

`from isaacsim import SimulationApp

simulation_app = SimulationApp({“headless”: False})
`

all the missing packages were found again, and the program launched successfully without any errors (I even successfully created a GroundPlane). But without from isaacsim import SimulationApp, almost all packages threw import errors.

I also tried PyCharm and encountered the same issue. Additionally, after setting up the environment, the editor provided no code completion at all. I noticed that some users on the forum had similar concerns. So, is this behavior intentional (by design)？
