QUESTION
I can plot a standard SkewT chart with mixing lines up to the default of p=600hPa, using the default call plot_mixing_lines() But I wanted to extend them up to the upper troposphere. I tried to do the following:
ANSWER
Answered 2021-Dec-03 at 18:55The problem here is that all the values in plevs are strings rather than values. I fixed that up with a plevs = list(map(int, plevs)), but you might find it easier to try:
QUESTION
Working to update an AWS Lambda function that relies on Flask / zappa that was originally written by another programmer. If Python modules are not imported / used by the scripts that are running in Lambda, can I remove them without any problem from requirements.txt?
The example file provided by AWS seems to have very few requirements. I just want to make sure that Cloudwatch continues to work and I'm not deleting things that AWS depends on implicitly.
Some of the packages that I am considering removing (since not imported by the Python scripts) include:
durationpypyrsistentplacebopytzpycparsertroposphereboto3
i.e. removing pyarrow and scikit-learn cut the redeploy time down from 3 minutes to 2 minutes. AWS Lambda also uses less RAM over shorter duration to execute.
ANSWER
Answered 2021-Sep-17 at 01:28It's hard to say as the dependencies vary across applications.
As far as I know, scikit-learn is a huge library and is not used by AWS. However, if your application or another package in your application uses it as a dependency, removing it might break your application.
Similarly pyarrow is also used by many packages. Some of the packages of your application could be using it internally.
I'm not sure but boto3 can also be removed as it's always available by default by AWS. But you might want to keep it since you'll be needing it for running the application locally.
For all other packages, I suggest you create a dependency tree of your packages using pipdeptree This will serve as starting point to determine which can could be removed.
QUESTION
I want to use AWS API Gateway HTTP API instead of old REST with my lambda functions, for pricing reasons.
Difference here: https://docs.aws.amazon.com/apigateway/latest/developerguide/http-api-vs-rest.html
What is the option in Zappa for this?
...ANSWER
Answered 2021-Sep-07 at 12:57As of Sept 2021, there is no support for HTTP API Gateways. There is an issue created to add support here: https://github.com/zappa/Zappa/issues/851
QUESTION
I wrote a script to import the characterization factors of the LCIA method EF 3.0 (adapated) on Brightway. I think it works fine as I see the right characterization factors on the Activity Browser (ex for the Climate Change method : but when I run calculations with the method, the results are not the same as on Simapro (where I got the CSV Import File from) : And for instance the result is 0 for the Climate Change method. Do you know what can be the issue ? It seems that the units are different but it is the same for the other methods that are available on Brightway.
Besides, I saw on another question that there would be a method implemented to import the EF 3.0 method, is it available yet ? Thank you very much for your help.

Answered 2021-Sep-01 at 15:29In LCA there's no agreement on elementary flows and archetypical emission scenarios / context (https://doi.org/10.1007/s11367-017-1354-3), and implementations of the impact assessment methods differ (https://www.lifecycleinitiative.org/portfolio_category/lcia/).
It is not unusual that the same activity and same impact assessment method returns different results in different software. There are some attempts to improve the current practices (see e.g , https://github.com/USEPA/LCIAformatter).
QUESTION
I'm trying to render information about planets.
================APP FILE============================
...ANSWER
Answered 2021-Jul-27 at 15:47It should be match.params.name beacuse you defined the dynamic path as /planets/:name which stores the dynamic value in as name
if you defined the route path like this /planets/:id, then the dynamic value would be saved as id

I'm trying to add an if statement in add_resource of troposphere, but I can't. Is there any workaround to do so?

QUESTION
Using Troposphere and Python I have created an AWS NLB. It works fine, I am just trying to add a new property to it. The property I am trying to add is "deregistration_delay.connection_termination.enabled". But when I try and update my stanza It does not like my syntax.
Here is my code block with the TargetGroupAttribute that I am trying to add.
...ANSWER
Answered 2021-Jun-03 at 16:29I was able to resolve the issue. I'm not sure why this was the case but I was able to successfully deploy the NLB with the Deregistration attribute enabled by the following.

QUESTION
I have a working Troposphere template that brings up my environment with a classic load balancer. I am modifying it to have the load balancer port 443 listener come up using the SSL Negotiation policy(cypher) ELBSecurityPolicy-TLS-1-2-2017-01.
It will let me generate the cloudformation yaml but when I try to create the stack using the generated yaml I get the error "Encountered unsupported property PolicyType" while it is trying to create the load balancer.
PolicyType is supported by Troposphere but not in AWS CF??
Any clues as to what I am doing wrong? Is there a better way?
I can not find any examples of updating the SSL negotiation using the Troposphere framework.
Here is the snippet of my Troposphere ELB listener code section that I think should do the magic -
...ANSWER
Answered 2021-Feb-26 at 06:18The Classic Load Balancer Policies should be specified under the Policies property, not the Listeners property. https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-elb.html#cfn-ec2-elb-policies
Remove the elb.Policy( ... ) from the Listerners=[ ...] property and add the Policies = [ elb.Policy( ... ), ... ] property to the LoadBalancer resource / object.

QUESTION
I'm using a Troposphere script to provision a CloudWatch metric filter and an alarm. In CloudWatch, it's possible to manually create an alarm that goes off based data that is aggregated from logs by the metric filter, but I would like to link the filter and alarm within the Troposphere script to save the manual labor if possible.
Here's what I have for the script (NOTE: there are some other resources defined and referenced below that are omitted for brevity):
...ANSWER
Answered 2020-Jun-05 at 08:04Based on the comments.
The issue was that Ref("metricNamespace") was different then "AWS/Logs"`. Subsequently, the MetricFilter and the Alarm were using different namespaces.
Setting the namespaces to the same value of BATCH-ERRORS fixed the problem.

Install troposphere
You can use troposphere like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
