SSL: CERTIFICATE_VERIFY_FAILED

[GEMSS3D]

Hi,

I installed Climada using step by step approach using anaconda. When I tried to run the test script, I get error message as "SSL: CERTFIFCATE_VERIFY_FAILED"

Can you please help me as what I am doing wrong here? I used the previous version in Matlab. I need to use this as soon as possible. Any help is greatly appreciated.

Thanks
Venkat

I do not know this error. @emanuel-schmid : do you have an idea what is the issue?

[emanuel-schmid]

@GEMSS3D - thanks for the inquiry. Don't know yet what's wrong. Are you connecting through a proxy maybe?

(which would be totally fine, I'm just trying to close in the source of this problem)

[GEMSS3D]

Hi,
Thanks for your feedback. I am not sure as to what you mean by proxy. I exactly followed the step by step approach after creating climada_env. I tried to install on my personal laptop. It doesn't work there either. I am not sure as what could be the problem. I am using latest version of anaconda. Any suggestions as how to install on windows 10 will be very useful for me. Thanks. Venkat

[emanuel-schmid]

Thank you.
Hm. I think it's not so much related to the installation but rather to the internet-connection. From what I see in the error message, the installation has been successfull.
Just to make sure - when you open this link

https://climada.ethz.ch/data-api/v1/dataset/?name=atl_prob_no_name&status=test_dataset&limit=100000

in a browser you get something like this:

[{"uuid": "ccfc9b14-db29-4504-91a7-716acb07f2e2", "data_type": {"data_type": "tropical_cyclone", ... , "expiration_date": null}]

and there is no warning about the connection not being secure?

[GEMSS3D]

Hi, Thanks for the follow up. I finally found that I have to install pip install python-certifi-win32 to get it work on my laptop and desktop machines. It is all working now. Thanks for the follow up. I will also provide this info in the github forum. Thanks Venkat Venkat S.

Oh? Many thanks for the solution! Good to know.
To be honest - I don't really understand how this solved the problem. But as long as it did, that's probably fine. (;
Best, Emanuel
