export PATH="$PATH:/usr/local/bin/graphviz" 替换/usr/local/bin/graphviz 为你的 Graphviz bin 目录的实际路径。 验证安装: 安装完成后,你可以在命令行或终端中输入 dot -V(注意是大写的 V)来检查 Graphviz 是否安装成功。如果安装成功,你应该能看到 Graphviz 的版本信息。 重新运行代码: 在确认 pydot、...
在 Linux 和 macOS 中,你可以在终端中执行: exportPYTHONPATH="/path/to/my_project/utils:$PYTHONPATH" 1. 在Windows 中,你可以在环境变量设置中进行类似操作,这样在运行 Python 代码时就不需要手动修改sys.path了。 三、序列图示例 为了更直观地理解模块导入的流程,以下是一个简单的序列图,展示了main.py如何...
添加环境路径: # 添加graphviz环境路径 importos os.environ["PATH"]+=os.pathsep+'D:/ProgramData/Anaconda3/envs/pytorch-py36/Library/bin/graphviz/' 1. 2. 3. 搜索路径: importsys importos # 打印当前python搜索模块的路径集 print(sys.path) # 打印当前文件所在路径 print("os.path.dirname(__file...
