`hpvm_reload` : Reloads HPVM weights (format used in `model_params` found here: [ADD link to Google Drive]) from directory specified in Benchmark constructor.
`hpvm_reload` : Reloads HPVM weights ('.bin' binary format used in `model_params` found here: https://gitlab.engr.illinois.edu/llvm/hpvm/-/tree/approx_hpvm_reorg_keras/hpvm/test/dnn_benchmarks/model_params) from directory path specified in the [Benchmark class constructor](https://gitlab.engr.illinois.edu/llvm/hpvm/-/blob/approx_hpvm_reorg_keras/hpvm/projects/keras/src/Benchmark.py#L17).
`keras_reload`: Reloads weights in Keras `.h5` file format
`keras_reload`: Reloads weights in Keras `.h5` file format with path to file specified in [Benchmark class constructor](https://gitlab.engr.illinois.edu/llvm/hpvm/-/blob/approx_hpvm_reorg_keras/hpvm/projects/keras/src/Benchmark.py#L20)
`frontend`: Invokes the HPVM frontend and dumps weights (in HPVM `.bin` format) in directory specified
`frontend`: Invokes the HPVM frontend and dumps weights (in HPVM `.bin` format) in the output directory specified. The constructor requires two paths:
*`data_dir`: Directory to dump weights specified specified in [constructor](https://gitlab.engr.illinois.edu/llvm/hpvm/-/blob/approx_hpvm_reorg_keras/hpvm/projects/keras/src/Benchmark.py#L21)
*`src_dir`: Directory to dump ApproxHPVM sources in HPVM-C (C with HPVM compiler intrinsics) specified in [constructor](https://gitlab.engr.illinois.edu/llvm/hpvm/-/blob/approx_hpvm_reorg_keras/hpvm/projects/keras/src/Benchmark.py#L22)
