<p>How to resolve the error no module named pandas when one node (in Airflow's DAG) is successful in using it(pandas) and the other is not?</p>

<p>I am unable to deduce as to why I am getting an error no module named pandas.</p>

<p>I have checked via <code>pip3 freeze</code> and yes, the desired pandas version does show up.</p>

<p>I have deployed this using docker on a kubernetes cluster.</p>

<p><a href="https://github.com/apache/incubator-airflow/blob/v1-10-stable/setup.py#L292" rel="nofollow noreferrer">Pandas is generally required</a>, and sometimes used in some hooks to return dataframes. Well, it's possible that Airflow was installed with <code>pip</code> and not <code>pip3</code> possibly being added as a Python 2 module and not a Python 3 module (though, using <code>pip</code> should have installed Pandas when one looks at the <a href="https://github.com/apache/incubator-airflow/blob/v1-10-stable/setup.py#L292" rel="nofollow noreferrer"><code>setup.py</code></a>).</p>

<p>Which Operator in your DAG is giving this error?
Do you have any PythonVirtualEnvironmentOperators or BashOperators running <code>python</code> from the command line (and thus possibly not sharing the same environment that you're checking has <code>pandas</code>)?</p>
