Hi @xintang082,

we have this clash, and we are working on this issue. Current workaround is to add this snippet to your script:

ROOT_DIR = f"{ospath.dirname(ospath.abspath(__file__))}/..".replace("\\", "/")
ROOT_LIB_DIR = f"{ROOT_DIR}/lib"
if platform == "win32":
    LIB_DIR = f"{ROOT_LIB_DIR}/windows"
elif platform == "linux":
    LIB_DIR = f"{ROOT_LIB_DIR}/linux"
else:
    raise OSError(
        "OS not supported, please compile dependencies and add value to LIB_DIR"
    )

# Add bin directory to maya plugin path
if "MAYA_PLUG_IN_PATH" in environ:
    separator = ":" if platform == "linux" else ";"
    environ["MAYA_PLUG_IN_PATH"] = separator.join([environ["MAYA_PLUG_IN_PATH"], LIB_DIR])
else:
    environ["MAYA_PLUG_IN_PATH"] = LIB_DIR

# Adds directories to path
syspath.insert(0, ROOT_DIR)
syspath.insert(0, LIB_DIR)

This snippet is all of our examples.
