Each calls `set_runtime` and is sequentially imported by the same parent python file. The second import fails at `set_runtime`. This worked in 3.0.1 (and as far back as 3.0.0a2).\r\n\r\n\r\n-   What commands did you run to trigger this issue? If you can provide a\r\n    [Minimal, Complete, and Verifiable example](http://stackoverflow.com/help/mcve)\r\n    this will help us understand the issue.\r\n\r\n Each module includes the following lines of code:\r\n\r\n```\r\nfrom pythonnet import set_runtime\r\nfrom clr_loader import get_coreclr\r\ndir_name = os.path.dirname(__file__)\r\nlinux_config_path = os.path.join(dir_name, \"pythonnet\", \"linux_config.json\")\r\nset_runtime(get_coreclr(runtime_config = linux_config_path))\r\n```\r\n\r\nlinux_config.json contains the following:\r\n```\r\n{\r\n  \"runtimeOptions\": {\r\n    \"tfm\": \"netcoreapp3.1\",\r\n    \"framework\": {\r\n      \"name\": \"Microsoft.NETCore.App\",\r\n      \"version\": \"3.1.0\"\r\n    }\r\n  }\r\n}\r\n```\r\n\r\n-   If there was a crash, please include the traceback here.\r\n\r\nThe second import throws the following error:\r\n\r\n```\r\nTraceback (most recent call last):\r\n  File \"worker.py\", line 4, in \u003cmodule\u003e\r\n    from modules.job_launcher import JobLauncher\r\n  File \"/tmp/8dba270eb2712ba/deployment_platform/modules/job_launcher.py\", line 25, in \u003cmodule\u003e\r\n    from misc_dir.v2.v2 import V2\r\n  File \"/tmp/8dba270eb2712ba/deployment_platform/misc_dir/v2/v2.py\", line 5, in \u003cmodule\u003e\r\n    set_runtime(get_coreclr(runtime_config = linux_config_path))\r\n  File \"/tmp/8dba270eb2712ba/antenv/lib/python3.8/site-packages/pythonnet/__init__.py\", line 26, in set_runtime\r\n    raise RuntimeError(f\"The runtime {_RUNTIME} has already been loaded\")\r\nRuntimeError: The runtime \u003cclr_loader.hostfxr.DotnetCoreRuntime object at 0x77e5a37ba850\u003e has already been loaded\r\n```\r\n\r\nSeems like this could be related to #2078/#2079, but that's just a guess.","author":{"url":"https://github.com/bayerju-ey","@type":"Person","name":"bayerju-ey"},"datePublished":"2023-09-08T00:41:59.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/2234/pythonnet/issues/2234"}
