無法載入 DLL 'Microsoft.Quantum.Simulator.Runtime.dll' (CentOS 7)

Question

我正试图让Microsoft的量子开发工具包在 CentOS 7 机器上工作。 我按照说明安装了dotnet，以及"Hello World"的琐碎dotnet工作。我还从yum安装了Visual Studio，并从Visual Studio资源管理器安装了Visual Studio的Microsoft Quantum Development Kit for Visual Studio。

克隆他们的 github 存储库后。我尝试：

dotnet_vm: Teleportation$ cd ~/Quantum/Samples/Teleportation/
dotnet_vm: Teleportation$ scl enable rh-dotnet21 bash
dotnet_vm: Teleportation$ dotnet run
/home/user/Quantum/Microsoft.Quantum.Canon/Microsoft.Quantum.Canon.csproj : warning NU1603: Microsoft.Quantum.Canon depends on NETStandard.Library (>= 2.0.2-servicing-25519-03) but NETStandard.Library 2.0.2-servicing-25519-03 was not found. An approximate best match of NETStandard.Library 2.0.2 was resolved. [/home/user/Quantum/Samples/Teleportation/TeleportationSample.csproj]

这看起来像相同的错误。 我尝试了我认为是 linux 等效的解决方案：

cp ~/.nuget/packages/microsoft.quantum.development.kit/0.2.1809.701-preview/runtimes/linux-x64/native/Microsoft.Quantum.Simulator.Runtime.dll ~/.nuget/packages/microsoft.quantum.development.kit/0.2.1809.701-preview/lib/netstandard2.0/

我仍然收到相同的错误。 另外，我的计算机上没有启用AVX指令集(这可能是一个潜在的问题？

例如

grep flags /proc/cpuinfo 
flags       : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm nopl pni cx16 hypervisor lahf_lm abm
flags       : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm nopl pni cx16 hypervisor lahf_lm abm
dotnet_vm: Teleportation$ 

我没有任何Windows经验，这些看起来不像典型的Linux库(不是.so或.a(。

问题： 我如何让它工作？

Answer 1

Microsoft.Quantum.Simulator.Runtime.dll是一个普通的Linux库(.so(，只是重命名了它，以便更容易支持跨平台。

它看起来确实与您链接的问题类似，但是您应该查看Ubuntu答案：使用ldd找出依赖项是什么并安装缺少的任何内容。就像那篇帖子一样，问题很可能是你错过了libgomp，但我不熟悉 CentOS。

未启用 AVX 会使速度变慢，尤其是在处理大量量子比特时，但您仍然应该能够运行。

Answer 2

按照 El capi 的回答，我查看了链接到的库：

例如

dotnet_vm: gcc-5.1.0$ ldd /home/user/.nuget/packages/microsoft.quantum.development.kit/0.2.1809.701-preview/lib/netstandard2.0/Microsoft.Quantum.Simulator.Runtime.dll

/lib64/ld-linux-x86-64.so.2 (0x00007f1fb656a000)

为了解决与 GLIBCXX_3.4.21 相关的版本控制问题，我安装了 gcc-5.1.0(及其依赖项(。 然后运行代码：

dotnet_vm: Teleportation$ dotnet run
