答案1
現在，PyPI 上列出的 opendr 最新版本（從中pip提取檔案）是版本 0.78。當您使用Python 3時，此版本僅列出支援Python 2。
我需要為 Python 3 安裝 opendr。
那你可能會希望用谷歌搜尋類似“opendr python 3“。這會傳回如下結果這個 GitHub 問題和這個 GitHub 問題討論該主題。簡而言之，似乎至少有一種方法可以安裝 opendr 和一些附加軟體套件（CentOS 沒有直接討論），而另一種選擇是安裝專案的分支。
列出的分叉 (Python 3)
需要注意的是，OSMesa API 似乎是一個癥結點。在上面的兩個 GitHub 問題中都間接引用了它，這個堆疊溢位問題以及您自己的錯誤輸出。
