python - windows 10安装后无法导入theano

Question

经过一周的努力，我仍然无法解决这个问题。我正在考虑放弃并在虚拟机上运行theano；似乎没有任何对 Windows 10 的支持!还是我错了？有一个简单的解决办法吗？

>>> import theano

嗯，不能将字节连接到 str 吗？这是什么意思？

您遇到的错误似乎是由于另一个子进程使用与您尝试编写的脚本相同的资源造成的。虽然这听起来微不足道，但我建议确保您具有管理员权限，或者至少具有所需资源的权限，和/或重新启动计算机以终止使用该模块的子进程。您还可以查看任务管理器并使用 python 终止任何/所有其他进程，但这可能需要更长的时间。(这可能是使用“资源”try_march_3v6ffkv9.exe的程序)
