ExecutableNotFound: failed to execute ['dot', '-Tsvg'], make sure the Graphviz executables are on yo
問題發生
在使用xgboost自帶功能繪圖的時候出現了問題
ExecutableNotFound: failed to execute ['dot', '-Tsvg'], make sure the Graphviz executables are on your systems' PATH
尋找原因
原因:graphviz本身是一個軟體,需要額外下載,並將其bin加入環境變數之中。
解決
下載工具包
Windows下前往 graphviz官網下載即可
ubuntu可以直接sudo apt install graphviz
亦可,如果不行,請前往graphviz官網下載
環境依賴請參考—— Ubuntu下安裝依賴的幾個解決方案
檢視檔案詳情(Windows,Linux通用命令)
下載完成後,使用dot -verison
命令,查詢bin資料夾地址,圖中白條處
Ubuntu環境下加入環境變數
然後加入環境變數,source /etc/profile
使其生效。
export PATH=$PATH:/usr/lib/x86_64-linux-gnu/graphviz
此時錯誤已經解決,可以繼續執行xgboost程式碼了。
