安装信号处理和机器学习工具箱 Bob 的问题

Question

我正在尝试从以下位置安装软件包：https://gitlab.idiap.ch/bob/bob.paper.ijcb2021_vision_transformer_pad。

我必须编辑 spec-file.txt 以使用每个包中可用的最早版本更新丢失的链接，并且还修改了构建文件以通过 http 而不是 ssh 连接。我在 Ubuntu 20.04 中使用 conda + mamba 并安装了 bob.extension，但是在运行 buildout 时我无法超越这一点。有关如何解决此问题的任何提示？谢谢。

这是我通过buildout得到的提示：

从您的评论看来，您安装了许多不同的 Python 版本； 2.7、3.6、3.7 和 3.8。

通常，安装多个版本的 Python 3 本身并不是问题。但它可能会导致错误。 特别是因为通常是一个python3链接，它只能指向一个版本。

所以我怀疑发生的事情是您为另一个 Python 版本安装了 bob.extensions，而不是您为 bob.paper 使用的那个版本。 或者你将它安装在不同的虚拟环境中（如果你正在使用那些）！

我的建议是检查您是否真的需要所有不同的版本。如果没有，请记下您为不同的 Python 版本安装了哪些软件包，并确定您需要哪些软件包。 然后删除除 3.8 之外的所有 Python 版本，并确保有一个链接 python3 指向 python3.8。 然后安装所有先决条件和bob.extensions 和bob.paper。

我从未在非 Windows 机器上使用过 conda，通常我会建议坚持使用来自 python.org 的 python，或者您的发行版中包含的任何软件包。
