【中文标题】如何让 tkinter 与 Blender v2.90 一起工作？【英文标题】：How do I get tkinter to work with Blender v2.90? 【发布时间】：2021-12-07 17:11:40 【问题描述】：我正在尝试获取一个使用 tkinter 运行的 Blender python 脚本。它应该打开一个 3d 面部对象，以允许用户改变鼻子以进行鼻整形手术。但是，它在很大程度上依赖于 tkinter 提供 GUI 以允许用户选择必要的文件的能力；并且代码不会超过它的导入语句。
代码如下：
import bpy

import tkinter as tk
from tkinter import filedialog

#select original data points xlsx file
def selectDataPointsFile():

dataPointsFile_path = filedialog.askopenfilename(filetypes=[("Excel files", "*.xlsx")])
activate += 1
if (activate == 3):
addPointsAndFaceButton['state'] = tk.NORMAL
newDataPointsButton['state'] = tk.NORMAL
#select new data points xlsx file
def selectNewDataPointsFile():
global newDataPointsFile_path
global activate
newDataPointsFile_path = filedialog.askopenfilename(filetypes=[("Excel files", "*.xlsx")])
activate += 1
if (activate == 3):
addPointsAndFaceButton['state'] = tk.NORMAL
faceObjectButton['state'] = tk.NORMAL
#select patient face obj file
def selectFaceObjectFile():
global faceObjectFile_path
global activate
faceObjectFile_path = filedialog.askopenfilename(filetypes=[("Object files", "*.obj")])

#select patient face obj file

这是它输出的错误：
我想知道问题是否可能是我没有正确地将 tkinter 安装到 Blender ./Scripts/modules 文件夹中...
感谢任何帮助，并在此先感谢。
【问题讨论】：
这能回答你的问题吗？ ImportError DLL load failed importing _tkinter @RandomDavis 没有，重新安装 64 位和 32 位 python 都没有解决这个问题。即使更改 Blender 在自己的文件结构中使用的 python 版本。 Blender 允许您使用自己的 gui 创建面板、按钮、文件对话框等，因此实际上不需要使用 tkinter。只需使用搅拌机。有关 Blender 脚本的更多详细信息，建议查看 Blender Stack Exchange。 @SylvesterKruin 谢谢，我去看看。我希望我不必重写这个程序，但我想我可能不得不这样做。 @godpleasehelp：我希望它不会那么难（我自己从来没有在 Blender 中编写过脚本）。但作为奖励，使用 Blender gui 工具将使它看起来是 Blender 原生的。 :-) 【参考方案1】：我已经使用 Blender 的内置 GUI 而不是 tkinter 重写了代码。
