-# TVM Runtime Frontend Support
-
-This crate provides an idiomatic Rust API for [TVM](https://github.com/apache/incubator-tvm) runtime frontend. Currently this requires **Nightly Rust** and tested on `rustc 1.32.0-nightly`
-
-## What Does This Crate Offer?
-
-Here is a major workflow
-
-1. Train your **Deep Learning** model using any major framework such as [PyTorch](https://pytorch.org/), [Apache MXNet](https://mxnet.incubator.apache.org/) or [TensorFlow](https://www.tensorflow.org/)
-2. Use **TVM** to build optimized model artifacts on a supported context such as CPU, GPU, OpenCL and specialized accelerators.
-3. Deploy your models using **Rust** :heart:
-
-### Example: Deploy Image Classification from Pretrained Resnet18 on ImageNet1k
-
-Please checkout [examples/resnet](examples/resnet) for the complete end-to-end example.
-
-Here's a Python snippet for downloading and building a pretrained Resnet18 via Apache MXNet and TVM
-
-```python
-block = get_model('resnet18_v1', pretrained=True)
-
-sym, params = relay.frontend.from_mxnet(block, shape_dict)
-# compile the model
-with relay.build_config(opt_level=opt_level):
- graph, lib, params = relay.build(
- net, target, params=params)
-# same the model artifacts
-lib.save(os.path.join(target_dir, "deploy_lib.o"))
-cc.create_shared(os.path.join(target_dir, "deploy_lib.so"),
- [os.path.join(target_dir, "deploy_lib.o")])
-
-with open(os.path.join(target_dir, "deploy_graph.json"), "w") as fo:
- fo.write(graph.json())
-with open(os.path.join(target_dir,"deploy_param.params"), "wb") as fo:
- fo.write(relay.save_param_dict(params))
-```
-
-Now, we need to input the artifacts to create and run the *Graph Runtime* to detect our input cat image
-
-
-
-as demostrated in the following Rust snippet
-
-```rust
- let graph = fs::read_to_string("deploy_graph.json")?;
- // load the built module
- let lib = Module::load(&Path::new("deploy_lib.so"))?;
- // get the global TVM graph runtime function
- let runtime_create_fn = Function::get("tvm.graph_runtime.create", true).unwrap();
- let runtime_create_fn_ret = call_packed!(
- runtime_create_fn,
- &graph,
- &lib,
- &ctx.device_type,
- &ctx.device_id
- )?;
- // get graph runtime module
- let graph_runtime_module: Module = runtime_create_fn_ret.try_into()?;
- // get the registered `load_params` from runtime module
- let ref load_param_fn = graph_runtime_module
- .get_function("load_params", false)
- .unwrap();
- // parse parameters and convert to TVMByteArray
- let params: Vec<u8> = fs::read("deploy_param.params")?;
- let barr = TVMByteArray::from(¶ms);
- // load the parameters
- call_packed!(load_param_fn, &barr)?;
- // get the set_input function
- let ref set_input_fn = graph_runtime_module
- .get_function("set_input", false)
- .unwrap();
-
- call_packed!(set_input_fn, "data", &input)?;
- // get `run` function from runtime module
- let ref run_fn = graph_runtime_module.get_function("run", false).unwrap();
- // execute the run function. Note that it has no argument
- call_packed!(run_fn,)?;
- // prepare to get the output
- let output_shape = &mut [1, 1000];
- let output = empty(output_shape, TVMContext::cpu(0), TVMType::from("float32"));
- // get the `get_output` function from runtime module
- let ref get_output_fn = graph_runtime_module
- .get_function("get_output", false)
- .unwrap();
- // execute the get output function
- call_packed!(get_output_fn, &0, &output)?;
- // flatten the output as Vec<f32>
- let output = output.to_vec::<f32>()?;
-```
-
-and the model correctly predicts the input image as **tiger cat**.
-
-## Installations
-
-Please follow TVM [installations](https://tvm.apache.org/docs/install/index.html), `export TVM_HOME=/path/to/tvm` and add `libtvm_runtime` to your `LD_LIBRARY_PATH`.
-
-*Note:* To run the end-to-end examples and tests, `tvm` and `topi` need to be added to your `PYTHONPATH` or it's automatic via an Anaconda environment when it is installed individually.
-
-## Supported TVM Functionalities
-
-### Use TVM to Generate Shared Library
-
-One can use the following Python snippet to generate `add_gpu.so` which add two vectors on GPU.
-
-```python
-import os
-import tvm
-from tvm import te
-from tvm.contrib import cc
-
-def test_add(target_dir):
- if not tvm.runtime.enabled("cuda"):
- print("skip {__file__} because cuda is not enabled...".format(__file__=__file__))
- return
- n = te.var("n")
- A = te.placeholder((n,), name='A')
- B = te.placeholder((n,), name='B')
- C = te.compute(A.shape, lambda i: A[i] + B[i], name="C")
- s = te.create_schedule(C.op)
- bx, tx = s[C].split(C.op.axis[0], factor=64)
- s[C].bind(bx, tvm.thread_axis("blockIdx.x"))
- s[C].bind(tx, tvm.thread_axis("threadIdx.x"))
- fadd_cuda = tvm.build(s, [A, B, C], "cuda", target_host="llvm", name="myadd")
-
- fadd_cuda.save(os.path.join(target_dir, "add_gpu.o"))
- fadd_cuda.imported_modules[0].save(os.path.join(target_dir, "add_gpu.ptx"))
- cc.create_shared(os.path.join(target_dir, "add_gpu.so"),
- [os.path.join(target_dir, "add_gpu.o")])
-
-
-if __name__ == "__main__":
- import sys
- if len(sys.argv) != 2:
- sys.exit(-1)
- test_add(sys.argv[1])
-```
-
-### Run the Generated Shared Library
-
-The following code snippet demonstrates how to load and test the generated shared library (`add_gpu.so`) in Rust.
-
-```rust
-extern crate tvm_frontend as tvm;
-
-use tvm::*;
-
-fn main() {
- let shape = &mut [2];
- let mut data = vec![3f32, 4.0];
- let mut arr = empty(shape, TVMContext::gpu(0), TVMType::from("float32"));
- arr.copy_from_buffer(data.as_mut_slice());
- let mut ret = empty(shape, TVMContext::gpu(0), TVMType::from("float32"));
- let mut fadd = Module::load(&Path::new("add_gpu.so")).unwrap();
- let fadd_dep = Module::load(&Path::new("add_gpu.ptx")).unwrap();
- assert!(fadd.enabled("gpu"));
- fadd.import_module(fadd_dep);
- fadd.entry();
- function::Builder::from(&mut fadd)
- .arg(&arr)
- .arg(&arr)
- .set_output(&mut ret)?
- .invoke()
- .unwrap();
-
- assert_eq!(ret.to_vec::<f32>().unwrap(), vec![6f32, 8.0]);
-}
-```
-
-**Note:** it is required to instruct the `rustc` to link to the generated `add_gpu.so` in runtime, for example by
-`cargo:rustc-link-search=native=add_gpu`.
-
-See the tests and examples custom `build.rs` for more details.
-
-### Convert and Register a Rust Function as a TVM Packed Function
-
-One can use `register_global_func!` macro to convert and register a Rust
-function of type `fn(&[TVMArgValue]) -> Result<TVMRetValue>` to a global TVM **packed function** as follows
-
-```rust
-#[macro_use]
-extern crate tvm_frontend as tvm;
-use std::convert::TryInto;
-use tvm::*;
-
-fn main() {
- register_global_func! {
- fn sum(args: &[TVMArgValue]) -> Result<TVMRetValue> {
- let mut ret = 0f32;
- let shape = &mut [2];
- for arg in args.iter() {
- let e = empty(shape, TVMContext::cpu(0), TVMType::from("float32"));
- let arg: NDArray = arg.try_into()?;
- let arr = arg.copy_to_ndarray(e).unwrap();
- let rnd: ArrayD<f32> = ArrayD::try_from(&arr).unwrap();
- ret += rnd.scalar_sum();
- }
- let ret_val = TVMRetValue::from(&ret);
- Ok(ret_val)
- }
- }
-
- let shape = &mut [2];
- let mut data = vec![3f32, 4.0];
- let mut arr = empty(shape, TVMContext::cpu(0), TVMType::from("float32"));
- arr.copy_from_buffer(data.as_mut_slice());
- let mut registered = function::Builder::default();
- let ret: f64 = registered
- .get_function("sum", true)
- .arg(&arr)
- .arg(&arr)
- .invoke()
- .unwrap()
- .try_into()
- .unwrap();
-
- assert_eq!(ret, 14f64);
-}
-```

-//! This module implements the [`NDArray`] type for working with *TVM tensors* or
-//! coverting from a Rust's ndarray to TVM `NDArray`.
-//!
-//! One can create an empty NDArray given the shape, context and dtype using [`empty`].
-//! To create an NDArray from a mutable buffer in cpu use [`copy_from_buffer`].
-//! To copy an NDArray to different context use [`copy_to_ctx`].
-//!
-//! Given a [`Rust's dynamic ndarray`], one can convert it to TVM NDArray as follows:
-//!
-//! # Example
-//!
-//! ```
-//! # use tvm_frontend::{NDArray, TVMContext, DataType};
-//! # use ndarray::{Array, ArrayD};
-//! # use std::str::FromStr;
-//! use std::convert::TryFrom;
-//!
-//! let a = Array::from_shape_vec((2, 2), vec![1f32, 2., 3., 4.])
-//! .unwrap()
-//! .into_dyn(); // Rust's ndarray
-//! let nd = NDArray::from_rust_ndarray(&a, TVMContext::cpu(0), DataType::from_str("float32").unwrap()).unwrap();
-//! assert_eq!(nd.shape(), Some(&mut [2, 2][..]));
-//! let rnd: ArrayD<f32> = ArrayD::try_from(&nd).unwrap();
-//! assert!(rnd.all_close(&a, 1e-8f32));
