A smaller CPU-only TensorFlow package is also available:

```
 pip install tensorflow-cpu
```

To update TensorFlow to the latest version, add the `--upgrade` flag to the
commands above.

*Nightly binaries are available for testing using the
[tf-nightly](https://pypi.python.org/pypi/tf-nightly) and
[tf-nightly-cpu](https://pypi.python.org/pypi/tf-nightly-cpu) packages on PyPI.*

你的伺服器（群）是可以被「消耗／利用」的「資源」，你的程式會使用 CPU 的計算時間，以及可用的 RAM 記憶體。

你想要消耗／利用多少系統資源？直覺上可能會想「不要太多」，但實際上，你大概會希望在「不當機」的前提下「盡可能用多一點」。

如果你花錢租了 3 台伺服器，卻只用了它們少量的 RAM 與 CPU，那你可能是在「浪費金錢」💸、也「浪費伺服器電力」🌎 等。

在那種情況下，可能更好的是只用 2 台伺服器，並以更高的比例使用它們的資源（CPU、記憶體、磁碟、網路頻寬等）。

另一方面，如果你有 2 台伺服器，且你使用了它們「100% 的 CPU 與 RAM」，某個時刻一個行程會要求更多記憶體，伺服器就得用磁碟當作「記憶體」（這可能慢上數千倍），甚至「當機」。或是某個行程需要做計算時，必須等到 CPU 再度空閒。

In that case, it could be better to have only 2 servers and use a higher percentage of their resources (CPU, memory, disk, network bandwidth, etc).
