title: How can I disable numba debug logging when DEBUG env variable is set?
body: <p>I have a lot of numba compiled functions and classes in my code. For the sake of testing I have to run my program like this:</p>
  
  <pre><code>DEBUG=True python3 main.py
  </code></pre>
  
  <p>But when I start my program like this, numba prints tons of debug messages to stderr. These messages look like this:</p>
  
  <pre><code>2020-02-05 16:28:30,886 - numba.interpreter - DEBUG - label 0:
  __numba_self_ = arg(0, name=__numba_self_) ['__numba_self_']
  args = arg(1, name=args)                 ['args']
  $4load_attr.1 = getattr(value=__numba_self_, attr=find) ['$4load_attr.1', '__numba_self_']
  $8call_function_ex.3 = call $4load_attr.1(*args, func=$4load_attr.1, args=[], kws=[], vararg=args) ['$4load_attr.1', '$8call_function_ex.3', 'args']
  $10return_value.4 = cast(value=$8call_function_ex.3) ['$10return_value.4', '$8call_function_ex.3']
  return $10return_value.4                 ['$10return_value.4']
  </code></pre>
  
  <p>How can I disable this output, without unsetting DEBUG environment variable?</p>
