### Активация виртуального окружения

Активируйте виртуально окружение командой:

//// tab | Linux, macOS

<div class="termy">

```console
$ source ./env/bin/activate
```

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console
$ .\env\Scripts\Activate.ps1

# Note that "_push" cache configs write to GCS buckets and require

# public read-only cache.
# The cache configs are different for MacOS and Linux

Das erstellt ein Verzeichnis `./env/` mit den Python-Binärdateien und Sie können dann Packages in dieser lokalen Umgebung installieren.

### Umgebung aktivieren

Aktivieren Sie die neue Umgebung mit:

//// tab | Linux, macOS

<div class="termy">

```console
$ source ./env/bin/activate
```

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console
$ .\env\Scripts\Activate.ps1

#    build. This should also match the system you're using--you cannot build
#    the TF MacOS package from Linux.
#      Ex. linux_x86        -- x86_64 Linux platform
#      Ex. linux_x86_cuda   -- x86_64 Linux platform, with Nvidia CUDA support
#      Ex. macos_arm64      -- arm64 MacOS platform
# 3. Add modifiers. Some modifiers for local execution are:
#      Ex. disk_cache -- Use a local cache

## Managing hermetic Python

To make sure that TensorFlow's build is reproducible, behaves uniformly across
supported platforms (Linux, Windows, MacOS) and is properly isolated from
specifics of a local system, we rely on hermetic Python (see
[rules_python](https://github.com/bazelbuild/rules_python)) for all build
and test commands executed via Bazel. This means that your system Python
installation will be ignored during the build and Python interpreter itself
