QUESTION
I have Airflow deployed in virtual env and in case I try to execute PythonVirtualenvOperator with import of the Airflow module (to get Variables for example) it gives me the AttributeError. Guess I do not fully understand how Airflow executes VirtualenvOperator, and therefore what to do to overcome it, so any suggestions and insights will be highly appreciated
My test DAG code
...ANSWER
Answered 2021-Apr-19 at 16:29It seems that you are confusing the use-cases for PythonVirtualenvOperator and PythonOperator.
If you simply want to run a Python callable in a task (callable_virtualenv()
in your case) you can use PythonOperator. In this case, it does not matter if you installed Airflow in a virtual environment, system wide, or using Docker.
What happens in your code is the following: PythonVirtualenvOperator
creates another virtual environment (which is completely unrelated to the one in which you run Airflow), installs Airflow into it, and tries to import Variable
. But this another Airflow installation is not configured and that is why you get those exceptions. You could set the AIRFLOW_HOME
environment variable for this second Airflow installation to the same directory as used by the first Airflow installation, and this should actually work, but it looks like an overkill to me.
So, what you can do is install colorama
into the same environment in which you installed Airflow and replace PythonVirtualenvOperator
by PythonOperator
.
BTW, those print()
inside the callable would be redirected into a log file and not printed to terminal, so it probably does not make much sense to use colorama
with them.

QUESTION
Currently working on a regression problem with tf2.0
. In order to prepare my dataset, I have used the following code:
ANSWER
Answered 2020-Jun-11 at 13:50Problem is that when you stack multiple LSTMs, we should use the argument, return_sequences = True
in LSTM Layer.
It is because if return_sequences = False
(default behavior), LSTM will return the Output of the Last Time Step
. But when we stack LSTMs, we will need the Output
of the Complete Sequence
rather than just the Last Time Step
.
