Review comment:
Because `use_sparse` only works for MLP, we should not expose it as a
top-level argument of `get_network`. We can move all sparse-related code into a
single branch. In this way, readers who are not interested in sparse-related
stuff only need to ignore this branch instead of ignoring code in multiple
places.
```suggestion
elif name == "sparse-mlp":
from tvm.relay import data_dep_optimization as do
from tvm.topi.sparse.utils import random_sparse_dense_params
mod, params = relay.testing.mlp.get_workload(
batch_size=batch_size, dtype=dtype, image_shape=image_shape,
num_classes=1000
)
bs_r = 1
bs_c = 1
sparsity = 0.85
mod, params = ddo.simplify_fc_transpose.convert(mod["main"], params)
# This is a test workload that manually transforms a dense model to
sparse
params = random_sparse_dense_params(mod, params, bs_r=bs_r,
bs_c=bs_c, density=1 - sparsity)
# Currently we only support to conver dense matmul to sparse dense
matmul
mod, params = ddo.bsr_dense.convert(mod, params, (bs_r, bs_c),
sparsity_threshold=0.8)
mod = tvm.IRModule.from_expr(mod)
else:
raise ValueError("Network not found.")
