pkg_resources.DistributionNotFound:找不到'wheel>=0.26；python_version >= "3"‘分发版，它是tensorboard所必需的

Question

当我从unity安装ml-agent时，我遇到了一个问题。在这一刻，我无法修复它。我正在通过anaconda运行env。我输入命令：mlagents-learn来验证安装

(unity_envIAJ) C:\Users\Rui\Documents\GitHub\ml-agents-release_10>mlagents-learn
Traceback (most recent call last):

    needed = self.resolve(parse_requirements(requirements))

During handling of the above exception, another exception occurred:

pkg_resources.DistributionNotFound: The 'wheel>=0.26; python_version >= "3"' distribution was not found and is required by tensorboard

python版本: 3.8.0张板: 2.4.0轮: 0.36.2

Answer 1

我必须将numpy更改为正确的版本，然后卸载所有与tensorboard和tensorflow相关的软件包，并仅通过conda tensorboard进行安装。
