+
+Candle is a minimalist ML framework for Rust with a focus on performance (including GPU support) 
+and ease of use. Try our online demos: 
+[whisper](https://huggingface.co/spaces/lmz/candle-whisper),
+[LLaMA2](https://huggingface.co/spaces/lmz/candle-llama2),
+[T5](https://huggingface.co/spaces/radames/Candle-T5-Generation-Wasm),
+[yolo](https://huggingface.co/spaces/lmz/candle-yolo),
+[Segment
+Anything](https://huggingface.co/spaces/radames/candle-segment-anything-wasm).
+
+## Get started
+
+Make sure that you have [`candle-core`](https://github.com/huggingface/candle/tree/main/candle-core) correctly installed as described in [**Installation**](https://huggingface.github.io/candle/guide/installation.html).
+
+Let's see how to run a simple matrix multiplication.
+Write the following to your `myapp/src/main.rs` file:
+```rust
+use candle_core::{Device, Tensor};
+
+fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let device = Device::Cpu;
+
+    let a = Tensor::randn(0f32, 1., (2, 3), &device)?;
+    let b = Tensor::randn(0f32, 1., (3, 4), &device)?;
+
+    let c = a.matmul(&b)?;
+    println!("{c}");
+    Ok(())
+}
+```
+
+`cargo run` should display a tensor of shape `Tensor[[2, 4], f32]`.
+
+
+Having installed `candle` with Cuda support, simply define the `device` to be on GPU:
+
+```diff
+- let device = Device::Cpu;
++ let device = Device::new_cuda(0)?;
+```
+
+For more advanced examples, please have a look at the following section.

+## FAQ
+
+### Why should I use Candle?
+
+Candle's core goal is to *make serverless inference possible*. Full machine learning frameworks like PyTorch
+are very large, which makes creating instances on a cluster slow. Candle allows deployment of lightweight
+binaries.
+
+Secondly, Candle lets you *remove Python* from production workloads. Python overhead can seriously hurt performance,
+and the [GIL](https://www.backblaze.com/blog/the-python-gil-past-present-and-future/) is a notorious source of headaches.
+
+Finally, Rust is cool! A lot of the HF ecosystem already has Rust crates, like [safetensors](https://github.com/huggingface/safetensors) and [tokenizers](https://github.com/huggingface/tokenizers).
+
+
+### Other ML frameworks
+
+- [dfdx](https://github.com/coreylowman/dfdx) is a formidable crate, with shapes being included
+  in types. This prevents a lot of headaches by getting the compiler to complain about shape mismatches right off the bat.
+  However, we found that some features still require nightly, and writing code can be a bit daunting for non rust experts.
+
+  We're leveraging and contributing to other core crates for the runtime so hopefully both crates can benefit from each
+  other.
+
+- [burn](https://github.com/burn-rs/burn) is a general crate that can leverage multiple backends so you can choose the best
+  engine for your workload.
+
+- [tch-rs](https://github.com/LaurentMazare/tch-rs.git) Bindings to the torch library in Rust. Extremely versatile, but they 
+  bring in the entire torch library into the runtime. The main contributor of `tch-rs` is also involved in the development
+  of `candle`.
+
+### Common Errors
+
+#### Missing symbols when compiling with the mkl feature.
+
+If you get some missing symbols when compiling binaries/tests using the mkl
+or accelerate features, e.g. for mkl you get:
+```
+  = note: /usr/bin/ld: (....o): in function `blas::sgemm':
+          .../blas-0.22.0/src/lib.rs:1944: undefined reference to `sgemm_' collect2: error: ld returned 1 exit status
+
+  = note: some `extern` functions couldn't be found; some native libraries may need to be installed or have their path specified
+  = note: use the `-l` flag to specify native libraries to link
+  = note: use the `cargo:rustc-link-lib` directive to specify the native libraries to link with Cargo
+```
+or for accelerate:
+```
+Undefined symbols for architecture arm64:
+            "_dgemm_", referenced from:
+                candle_core::accelerate::dgemm::h1b71a038552bcabe in libcandle_core...
+            "_sgemm_", referenced from:
+                candle_core::accelerate::sgemm::h2cf21c592cba3c47 in libcandle_core...
+          ld: symbol(s) not found for architecture arm64
+```
+
+This is likely due to a missing linker flag that was needed to enable the mkl library. You
+can try adding the following for mkl at the top of your binary:
+```rust
+extern crate intel_mkl_src;
+```
+or for accelerate:
+```rust
+extern crate accelerate_src;
+```
+
+#### Cannot run the LLaMA examples: access to source requires login credentials
+
+```
+Error: request error: https://huggingface.co/meta-llama/Llama-2-7b-hf/resolve/main/tokenizer.json: status code 401
+```
+
+This is likely because you're not permissioned for the LLaMA-v2 model. To fix
+this, you have to register on the huggingface-hub, accept the [LLaMA-v2 model
+conditions](https://huggingface.co/meta-llama/Llama-2-7b-hf), and set up your
+authentication token. See issue
+[#350](https://github.com/huggingface/candle/issues/350) for more details.
+
+#### Missing cute/cutlass headers when compiling flash-attn
+
+```
+  In file included from kernels/flash_fwd_launch_template.h:11:0,
+                   from kernels/flash_fwd_hdim224_fp16_sm80.cu:5:
+  kernels/flash_fwd_kernel.h:8:10: fatal error: cute/algorithm/copy.hpp: No such file or directory
+   #include <cute/algorithm/copy.hpp>
+            ^~~~~~~~~~~~~~~~~~~~~~~~~
+  compilation terminated.
+  Error: nvcc error while compiling:
+```
+[cutlass](https://github.com/NVIDIA/cutlass) is provided as a git submodule so you may want to run the following command to check it in properly.
+```bash
+git submodule update --init
+```
+
+#### Compiling with flash-attention fails
+
+```
+/usr/include/c++/11/bits/std_function.h:530:146: error: parameter packs not expanded with ‘...’:
+```
+
+This is a bug in gcc-11 triggered by the Cuda compiler. To fix this, install a different, supported gcc version - for example gcc-10, and specify the path to the compiler in the CANDLE_NVCC_CCBIN environment variable.
+```
+env CANDLE_NVCC_CCBIN=/usr/lib/gcc/x86_64-linux-gnu/10 cargo ...
+```
+
+#### Linking error on windows when running rustdoc or mdbook tests
+
+```
+Couldn't compile the test.
+---- .\candle-book\src\inference\hub.md - Using_the_hub::Using_in_a_real_model_ (line 50) stdout ----
+error: linking with `link.exe` failed: exit code: 1181
+//very long chain of linking
+ = note: LINK : fatal error LNK1181: cannot open input file 'windows.0.48.5.lib'
+```
+
+Make sure you link all native libraries that might be located outside a project target, e.g., to run mdbook tests, you should run:
+
+```
+mdbook test candle-book -L .\target\debug\deps\ `
+-L native=$env:USERPROFILE\.cargo\registry\src\index.crates.io-6f17d22bba15001f\windows_x86_64_msvc-0.42.2\lib `
+-L native=$env:USERPROFILE\.cargo\registry\src\index.crates.io-6f17d22bba15001f\windows_x86_64_msvc-0.48.5\lib
+```
+
+#### Extremely slow model load time with WSL
+
+This may be caused by the models being loaded from `/mnt/c`, more details on
+[stackoverflow](https://stackoverflow.com/questions/68972448/why-is-wsl-extremely-slow-when-compared-with-native-windows-npm-yarn-processing).
+
+#### Tracking down errors
+
+You can set `RUST_BACKTRACE=1` to be provided with backtraces when a candle
+error is generated.
