您好，我有一个项目，具有以下文件夹结构（抽象）：

.
└── root/
    ├── ExRate_Service/
    │   ├── MyOwnPythonScripts... 
    │   └── Program.py
    ├── ExRate_API/
    │   ├── ExRate_API/
    │   │   ├── Classes...
    │   │   ├── ExRate_API.csproj
    │   │   └── Program.cs
    │   ├── ExRate_API.Tests/
    │   │   └── Tests...
    │   └── ExRate_API.sln
    └── Dockerfile

Dockerfile包含以下内容，并且构建时没有错误：

WORKDIR /app

COPY --from=package /app/out ExRate_API
ENTRYPOINT ["dotnet", "ExRate_API/ExRate_API.dll"]
EXPOSE 80

下面是调用python脚本的API代码（我有这个方法的第二个版本，如果它不在容器中，它就运行，当API在本地运行而没有容器时，它工作正常）

public string getOutputInContainer(string targetCurrency, string baseCurrency)
        {
            _logger.LogInformation($"Container method running");

            var scriptPath = "/app/ExRate_Service/Program.py";

            var output = string.Empty;
            var process = new Process
            {
                StartInfo = new ProcessStartInfo
                {
                    FileName = "/usr/local/lib/python3.9",
                    Arguments = scriptPath + $" -b {targetCurrency} -t {baseCurrency}",
                    UseShellExecute = false,
                    RedirectStandardOutput = true,
                    RedirectStandardError = true,
                    CreateNoWindow = true
                },
                EnableRaisingEvents = true
            };

            process.ErrorDataReceived += (sender, e) =>
            {
                if (!string.IsNullOrEmpty(e.Data))
                {
                    _logger.LogInformation($"Error from process: {e.Data}");
                }
            };
            process.OutputDataReceived += (sender, e) =>
            {
                if (!string.IsNullOrEmpty(e.Data))
                {
                    _logger.LogInformation($"Output from process: {e.Data}");
                    output += e.Data;
                }
            };

            process.Start();
            process.BeginErrorReadLine();
            process.BeginOutputReadLine();
            process.WaitForExit();

            _logger.LogInformation($"Raw output: {output}");

            var historicalData = JsonConvert.DeserializeObject<Dictionary<string, object>>(output.Substring(0, output.IndexOf("}") + 1));
            var forecast = JsonConvert.DeserializeObject<Dictionary<string, object>>(output.Substring(output.IndexOf("}") + 1));

            _logger.LogInformation($"Forecast: {JsonConvert.SerializeObject(forecast)}");

            var result = new Dictionary<string, Dictionary<string, object>>();
            result.Add("historicalData", historicalData ?? new Dictionary<string, object>());
            result.Add("forecast", forecast ?? new Dictionary<string, object>());

            _logger.LogInformation($"Result: {JsonConvert.SerializeObject(result)}");

            var json = JsonConvert.SerializeObject(result, Formatting.Indented);

            _logger.LogInformation($"Final JSON: {json}");

            return json;
        }

当API在容器中使用此命令docker run -ti --rm -p 8080:80 exrate运行时，我收到以下错误：

当我进入容器的bash控制台时，我可以看到python3和dependeinces都安装好了，它们都在那里。那么为什么我的脚本找不到numpy（假设那是第一个失败的）或任何其他的呢？
我不是一个 Docker Maven，这是我第一次尝试建立一个如此复杂的容器。
整个项目托管在github here上
任何帮助或指示将不胜感激。
