+# Inference with Python or C++ Prediction Engine
+
+Since the 2.x branch, inference with Python or C++ prediction engines has been a significant feature. This functionality allows users to load OCR-related models and perform inference without installing the wheel package.
+
+Due to differences in pre-processing, post-processing, and concatenation details compared to the wheel package, the inference results may slightly vary, and the two cannot be directly interchanged.
+
+For specific usage instructions, please refer to the following documents:
+
+* [Inference with Python Prediction Engine](../../version2.x/legacy/python_infer.md)
+* [Inference with C++ Prediction Engine](../../version2.x/legacy/cpp_infer.md)
+* [List of Supported Models](../../version2.x/legacy/model_list_2.x.md)
