我如何运行 sphinxtrain 脚本？

Question

我正在使用 sphinx 构建我自己的声音识别模型，我一步一步按照教程进行操作，一切正常，直到我应该运行 sphinixtrain 的 python 脚本（它的作用是在正常情况下执行一组 perl 文件抛出终端）但对我来说，程序只用选择的编辑器一个一个地打开文件而不执行它们！（观看其他教程视频，下面的代码工作正常）

培训师代码：

    print("Failed to find sphinxtrain binaries. Check your installation")
    exit(1)

 # Perl script want forward slashes

Answer 1

解决此问题的另一种方法是在 os.system 调用中明确调用 Perl 解释器

即

ret = os.system('perl ' + sphinxpath + "/scripts/" + step)

Answer 2

通过将 perl 文件（带有 pl 扩展名）关联到 perl.exe 解决
