-# Building torchaudio packages for release
-
- ## Anaconda packages
-
- ### Linux
-
- ```bash
-docker run -it --ipc=host --rm -v $(pwd):/remote soumith/conda-cuda bash
-cd remote
-PYTHON_VERSION=3.7 packaging/build_conda.sh
-```
-
-To install bz2,
-```bash
-cd /opt/conda/conda-bld/linux-64/
-# install dependencies
-conda install pytorch-cpu=1.1.0
-conda install sox
-# install torchaudio
-conda install /opt/conda/conda-bld/linux-64/torchaudio-cpu-0.2.0-py27_1.tar.bz2
-```
-
-To upload bz2,
-```bash
-anaconda upload -u pytorch /opt/conda/conda-bld/linux-64/torchaudio*.bz2
-```
-
- ### OSX
-
- ```bash
-# create a fresh anaconda environment / install and activate it
-PYTHON_VERSION=3.7 packaging/build_conda.sh
-```
-
-To install bz2,
-```bash
-cd /Users/jamarshon/anaconda3/conda-bld/osx-64/
-# activate conda env (e.g
-conda info --envs
-conda activate /Users/jamarshon/minconda_wheel_env_tmp/envs/env2.7
-# install dependencies
-conda install pytorch-cpu=1.1.0
-conda install sox
-# install torchaudio
-# and then try installing (e.g
-conda install /Users/jamarshon/anaconda3/conda-bld/osx-64/torchaudio-0.2.0-py27_1.tar.bz2
-```
-
-To upload bz2,
-```bash
