我需要将Tensorflow添加到我的require.txt中。首先，我添加了没有特定版本的“ tensorflow”，但是在Gitlab-CI中，lints向我提供了我需要添加特定版本的信息，因此我添加了它，它看起来像“ tensorflow == 2.0.0-rc0”，但是在Gitlab中-CI我知道了：

ERROR: Could not find a version that satisfies the requirement tensorflow==2.0.0-rc0 (from -r requirements.txt (line 2)) (from versions: none)
ERROR: No matching distribution found for tensorflow==2.0.0-rc0 (from -r requirements.txt (line 2))

CI返回：

$ python --version
Python 3.8.0
$ pip install --upgrade pip
Requirement already up-to-date: pip in /usr/local/lib/python3.8/site-packages (19.3.1)
$ pip install --upgrade setuptools
