然后点击确定即可。此时Pycharm底部会出现File Transfer栏,显示代码文件的同步信息: 此时运行代码,使用的就是服务器的Python解释器。后续对代码的每一次修改,都会在保存后自动上传服务器。 5.3. 常见问题 在文件同步过程中,若出现报错: Failed to change timestamp of the file ...

Many techniques are applied to minimize the overall overhead during code execution to reduce the inevitable skew introduced by VizTracer (the report saving part is not as critical). For example, VizTracer tries to use the CPU timestamp counter instead of a syscall to get the time when available...
