linux:

pip install horovod

pip install horovod --no-cache-dir

HOROVOD_WITH_MXNET=1 pip install horovod[mxnet]

`HOROVOD_WITH_MXNET=1 pip install horovod[mxnet]==0.19 --no-cache-dir`

下载自己安装：

[https://pypi.org/project/horovod/\#files][https_pypi.org_project_horovod_files]

python setup.py build --force develop

并不是所有版本都支持，支持的版本说明：

frameworks:

$ pip install horovod[tensorflow,keras,pytorch,mxnet,spark]

In addition to specifying framework requirements individually, you can require all frameworks collectively:

$ pip install horovod[all-frameworks]

This is useful when building Horovod as part of a larger collection of dependencies at once, relying on the pip compiler to determine the correct install order.

### TensorFlow ###

To ensure that Horovod is built with TensorFlow support enabled:

$ HOROVOD_WITH_TENSORFLOW=1 pip install horovod[tensorflow]

To skip TensorFlow, set `HOROVOD_WITHOUT_TENSORFLOW=1` in your environment.

If you’ve installed TensorFlow from [PyPI][], make sure that the `g++-4.8.5` or `g++-4.9` or above is installed.

### PyTorch ###

To ensure that Horovod is built with PyTorch support enabled:

$ HOROVOD_WITH_PYTORCH=1 pip install horovod[pytorch]

To skip PyTorch, set `HOROVOD_WITHOUT_PYTORCH=1` in your environment.

If you’ve installed PyTorch from [PyPI][PyPI 1], make sure that the `g++-4.9` or above is installed.

### MXNet ###

To ensure that Horovod is built with MXNet CPU support enabled:

$ HOROVOD_WITH_MXNET=1 pip install horovod[mxnet]

Some MXNet versions do not work with Horovod:

*  MXNet 1.4.0 and earlier have [GCC incompatibility issues][]. Use MXNet 1.4.1 or later with Horovod 0.16.2 or later to avoid these incompatibilities.
 *  MXNet 1.5.1, 1.6.0, 1.7.0, and 1.7.0.post1 are missing MKLDNN headers, so they do not work with Horovod. Use 1.5.1.post0, 1.6.0.post0, and 1.7.0.post0, respectively.
 *  MXNet 1.6.0.post0 and 1.7.0.post0 are only available as mxnet-cu101 and mxnet-cu102.

To skip MXNet, set `HOROVOD_WITHOUT_MXNET=1` in your environment.

### Keras ###

Standalone Keras support is currently only available for the TensorFlow backend.

To ensure that Horovod is built with Keras support available:

$ HOROVOD_WITH_TENSORFLOW=1 pip install horovod[tensorflow,keras]

There are no plugins built for Keras, but the TensorFlow plugin must be enabled in order to use Horovod with Keras.

### Spark ###

Horovod can be used with Spark in combination with any of the frameworks above.

To ensure Horovod has all the necessary requirements in order to run on top of Spark:

$ pip install horovod[spark]
