这个测试文件里为什么是 @pytest.mark.api_linalg_det_vartype 而不是 @pytest.mark.api_linalg_inv_vartype？
然后应该要把 apibase.py 里的

if isfunction(func)

判断改为

if isfunction(func) or callable(func) and not hasattr(func, '__mro__')

使其能够正确识别 builtin_function_or_method 类型（如 paddle.linalg.inv）作为函数而不是类

在paddle/_init_.py最后会 monkey_patch_generated_methods_for_tensor，重新将公开API：paddle.*、paddle.tensor.*、F.* 换成有python接口的，而paddle.linalg.inv导入了原始的pybind的inverse。这里需要看看调整下这一系列导入方式。在patch完之后，再从from paddle.tensor import inverse as inv就没问题。

问题描述

CI 测试中会有 CE-Framework 测试失败，经过本地测试复现失败：

pytest PaddleTest/framework/api/linalg/test_inv.py

这是由于 paddle.linalg.inv 未定义造成的

问题拆解

API 路径缺失：操作在 paddle/phi/ops/yaml/python_api_info.yaml 中仅配置了 paddle.inverse 和 paddle.Tensor.inverse 两个路径，未包含 paddle.linalg.inv
代码生成器限制：monkey_patch_gen.py 中的 ClassifyAPIByPrefix 函数仅支持三种硬编码前缀：

if prefix == "paddle.":
    paddle_func_map.append(...)
elif prefix == "paddle.Tensor.":
    tensor_method_map.append(...)
elif prefix == "paddle.nn.functional.":
    nn_func_map.append(...)
else:
    raise Exception("Unsupported Prefix " + prefix, "API : " + name)

这意味着即使在 python_api_info.yaml 中直接添加 paddle.linalg.inv 也会因不支持前缀而抛出异常
3. paddle.linalg.inv 只是暴露了这个问题，需要为类似的 API 手动添加特殊处理逻辑

解决方案

生成器增强：扩展 monkey_patch_gen.py 以支持通用模块路径

新增 generic_funcs_map 储存 (module_path, method_name, method) 元组
修改 ClassifyAPIByPrefix 函数将未匹配的 paddle.* 前缀纳入通用映射表
在运行时通过 getattr() 动态调用目标模块并设置属性

优点: 未来添加类似路径的 API，如 paddle.fft.* 等时，只要在 yaml 文件中配置即可，方便快捷

修改文件

paddle/fluid/eager/auto_code_generator/generator/monkey_patch_gen.py: 支持通用模块路径
paddle/phi/ops/yaml/python_api_info.yaml: 在 inverse 操作配置中添加 paddle.linalg.inv

修改后测试：

python paddle/test/legacy_test/test_inverse_op.py  # 测试通过
pytest PaddleTest/framework/api/linalg/test_inv.py  # 测试通过

这样能解决一个单点的API导入问题。

但这个是一个共性的问题，后续比如这里的

cholesky, cholesky_inverse, cholesky_solve,

如果下沉也都会遇到类似的问题，调研下更通用的解决方案，参考：

修改patch顺序，提前monkey_patch_generated_methods_for_tensor的位置

修改monkey_patch_generated_methods_for_tensor逻辑，目前只会根据python_api_info.yaml里的paddle.*来配置patch，如果这个name支持paddle.linalg.inv或任意其他路径的patch也能解决问题

+            -1

整体合并成一套逻辑，这一块整体重构，不用在之前局限的设计上打补丁
