## Summary of Changes Hello @Dayuxiaoshui, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the PyTorch frontend for TVM Relax by introducing support for several key operations. It enables the conversion of PyTorch models that utilize sparse matrix multiplications and random number generation, as well as `as_strided` operations, into TVM Relax modules. This broadens the range of PyTorch models that can be successfully compiled and optimized by TVM. ### Highlights * **Sparse Matrix Operations**: Added support for PyTorch sparse matrix multiplication (`_sparse_mm`) and sparse addmm operations (`_sparse_addmm`) within the Relax frontend, converting sparse inputs to dense for processing. * **Random Number Generation**: Implemented support for `torch.randn` by introducing a `_randn` method, which currently acts as a placeholder by emitting `relax.op.zeros` until native random number generation is available in TVM. * **Tensor Conversion Utility**: Introduced a new static method `_convert_pytorch_tensor_to_tvm` to handle the robust conversion of PyTorch tensors to TVM tensors, including the necessary conversion of sparse PyTorch tensors to dense format and a fallback mechanism for DLPack conversion failures. * **Strided Tensor Support**: Added support for `torch.as_strided` operations, specifically for view-like cases where the provided strides align with a contiguous layout, translating them to `relax.op.reshape`. * **Operation Registration**: Registered the newly added `_sparse_mm.default`, `_sparse_addmm.default`, `mul`, `as_strided.default`, and `randn.default` operations in the `create_convert_map` to enable their translation during the conversion process. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
