title: Iron python cannot find {"No module named numpy"}
body: <p>I am attempting to launch a python file from a c# program using Iron python but i am getting the error ironpython.runtime.exceptions.importexception{"No module named numpy"} although the python file does import numpy</p>
  
  <p>c# code:</p>
  
  <pre><code>private void btnStartPython_Click(object sender, EventArgs e)
      {
          ScriptEngine engine = Python.CreateEngine();
           engine.ExecuteFile(@"C:\Users\matth\Desktop\testmctest.py");
      }
  </code></pre>
  
  <p>python code:</p>
