Installation issues on Apple M1 Pro.

Hi I am trying to install this on my Apple M1 Pro. I am getting the following error. Tried installing rustc but it did not help. Any workaround is appreciated.

running build_ext
      running build_rust
      info: syncing channel updates for 'nightly-2020-05-14-aarch64-apple-darwin'
      info: latest update on 2020-05-14, rust version 1.45.0-nightly (75e1463c5 2020-05-13)
      error: target 'aarch64-apple-darwin' not found in channel.  Perhaps check https://doc.rust-lang.org/nightly/rustc/platform-support.html for available targets
      error: can't find Rust compiler
      
      If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.
      
      To update pip, run:
      
          pip install --upgrade pip
      
      and then retry package installation.
      
      If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

  note: This error originates from a subprocess, and is likely not a problem with pip.

Never mind. I figured it out. Made several changes to the files under the model folder to align it with the latest version of the Transformer.
