无法加载 DLL 'Microsoft.Quantum.Simulator.Runtime.dll'

Question

尝试通过运行传送示例程序验证我的 Q# 环境时出现无法加载 DLL 'Microsoft.Quantum.Simulator.Runtime.dll' 错误。

dotnet build
dotnet run

platform windows 7 64 bit with AVX enabled. vscode with .NET Core SDK 2.0


Unhandled Exception: System.DllNotFoundException: Unable to load DLL 'Microsoft.Quantum.Simulator.Runtime.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
   at Microsoft.Quantum.Simulation.Simulators.QuantumSimulator.Init()
   at Microsoft.Quantum.Simulation.Simulators.QuantumSimulator..ctor(Boolean throwOnReleasingQubitsNotInZeroState, Nullable`1 randomNumberGeneratorSeed, Boolean disableBorrowing)
   at Microsoft.Quantum.Examples.Teleportation.Program.Main(String[] args) in C:\opt\workspace\quantum\Quantum\Samples\Teleportation\Program.cs:line 13

Answer 1

复制 Microsoft.Quantum.Simulator.Runtime.dll 来自 C:\Users\{user}\.nuget\packages\microsoft.quantum.development.kit[=12=].2.1802.2202-preview\runtimes\win10-x64 到 C:\Users\{user}\.nuget\packages\microsoft.quantum.development.kit[=13=].2.1802.2202-preview\lib\netstandard2.0。虽然我没有用较旧的 Microsoft Quantum 开发工具包版本对此进行测试，但 0.2.1802.2202 版本似乎有问题。确保检查 AVX 是否可用，您可以使用 CPU-Z 工具在说明部分进行检查。

然后运行 dotnet run 这应该导致

Round 0:        Sent False,     got False.
Teleportation successful!!

Round 1:        Sent True,      got True.
Teleportation successful!!

Round 2:        Sent False,     got False.
Teleportation successful!!

Round 3:        Sent False,     got False.
Teleportation successful!!

Round 4:        Sent False,     got False.
Teleportation successful!!

Round 5:        Sent False,     got False.
Teleportation successful!!

Round 6:        Sent False,     got False.
Teleportation successful!!

Round 7:        Sent True,      got True.
Teleportation successful!!

模拟器只有 tested/supported Windows 10。我强烈建议升级您的系统。

Answer 3

在 Ubuntu bionic 下，我不得不安装 libgomp1 因为 Microsoft.Quantum.Simulator.Runtime.dll 依赖于 libgomp.so.1.

sudo apt install libgomp1

这里可以看到依赖

ldd -r ~/.nuget/packages/microsoft.quantum.development.kit/0.2.1802.2202-preview/runtimes/linux-x64/native/Microsoft.Quantum.Simulator.Runtime.dll

linux-vdso.so.1 (0x00007ffcbb4f4000)

libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fd536e99000)
