I am trying to deploy an Airfow DAG to MWAA.
My requirements.txt:
apache-airflow[amazon] == 3.2.0
I import EcsOperator like this:
from airflow.contrib.operators.ecs_operator import EcsOperator
However, I get this error:
Broken DAG: [/usr/local/airflow/dags/mydag.py] Traceback (most recent call last):
File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
File "/usr/local/airflow/dags/mydag.py", line 4, in <module>
from airflow.contrib.operators.ecs_operator import EcsOperator
ImportError: cannot import name 'EcsOperator' from 'airflow.contrib.operators.ecs_operator' (/usr/local/lib/python3.7/site-packages/airflow/contrib/operators/ecs_operator.py)
What am I doing wrong here?

You might be referencing a different version (1.10.12?) of the Airflow documentation.
airflow.contrib.operators.ecs_operator (1.10.12)
The documentation for 3.2.0 is here. You can import the EcsOperator like this:
from airflow.providers.amazon.aws.operators.ecs import EcsOperator
airflow.providers.amazon.aws.operators.ecs (3.2.0)
The correct requirements.txt:
(empty)
And the correct import:
from airflow.providers.amazon.aws.operators.ecs import ECSOperator
Note the casing!
There are several issues here so I'll compile a detailed answer since privious answers didn't cover all of them.
First, the updated import path (provider release 3.2.0) is:
from airflow.providers.amazon.aws.operators.ecs import EcsOperator
The reason this doesn't work for you is because you install the provider with extras as:
apache-airflow[amazon]
as explained in the provider extra docs when installing provider in that manner you get the provider version which was released at the time of the Airflow version that you are using. Thus you are not guaranteed to get the updated provider version. So in case you are using Airflow 2.2.4 (latest at the time of writing this answer) you will get Amazon provider version 3.0.0 which is not the most recent one.
To get updated provider you should install it as:
pip install apache-airflow-providers-amazon
if you like to pick a specific version then:
pip install apache-airflow-providers-amazon==3.2.0
Please note that you should always install from constraint files provided by Airflow. Example:
pip install "apache-airflow-providers-amazon" --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-main/constraints-3.7.txt"
Note that the provider is referring to constraints-main which constantly updated and not to constraints-2.2.4 or any other specific Airflow version.
You can read more about it in the doc about Installation and upgrading of Airflow providers separately.
I am trying to call rpy2.robjects which is giving below mentioned error. I am using rpy2 package(3.4.5) in python 3.5.10. R installed version is 3.4.1.

I am running this command from AWS EC2 instance where it is required to call an R function from python.
The same command is working in windows after setting R_HOME.
In EC2 instance, tried 2 paths for R_HOME,
os.environ['R_HOME'] = '/usr/lib64/R/'
or '/usr/bin/R'
The issue persists in both cases.
R.home is '/usr/lib64/R/' (R prompt)
rpy2 3.4.x requires Python >=3.6 as described in the documentation (installation section). The error you see is because Python 3.5 did not support typing.
You need to upgrade your Python version. Python 3.5 support ended 1 year ago and its not safe to use it - you may be exposed to unpatched security bugs. Given that support for 3.6 ends in two months I would recommend upgrading straight to 3.7 or 3.8.

I receive the following error:

Can I get some guidance on what is missing?
Looks like the module for Azure-Core has not been installed.
Run
pip install azure-core
Since the error you re receiving is below :
from azure.core.exceptions import ResourceNotFoundError
I want to use the raspberry pi to send values to the Oracle11g database, but when I run import cx_Oracle syntax for that process, I get the following error:
Traceback (most recent call last):
File "/home/pi/20190222ex01.py", line 1, in <module>
import cx_Oracle
File "/usr/lib/python3/dist-packages/thonny/backend.py", line 317, in _custom_import
module = self._original_import(*args, **kw)
ImportError: No module named 'cx_Oracle'
How can I solve this problem?
Update: Oracle has released Oracle Instant Client ARM64: https://www-sites.oracle.com/database/technologies/instant-client/linux-arm-aarch64-downloads.html
It means, that you have not installed module cx_Oracle.
First you must install Oracle driver with PIP:
python -m pip install cx_Oracle --upgrade
Hope it helped you.

When I add 'MongoDBLibrary' library in the RIDE it showing in red (means library is not installed properly),
when i ran the same using eclipse + Maven project i got the following error

Make sure you have installed PyMongo (or bson):
pip install pymongo
pip install bson (don't know if still required then)
