Acumos model onboarding python CLI

Question

I'm trying to onboard a simple python model from CLI as shown in the related tutorial . After providing the onboarding token (user:api-token) I'm getting the error below. The Acumos platform has been deployed using the AIO tools using prep-deploy process. I was able to dump the same model and onboard using the web UI.

UPDATE

I've solved by adding the following line into the python script:

os.environ['CURL_CA_BUNDLE'] = ""

In addition to that I also had to change the push url ("acumos/onboarding-app/v2/models") as it was wrongly reported in the acumos python client library ("acumos/onboarding-app/v2/push").

Answer 1

I recomend you to add the following in your python script

os.environ['CURL_CA_BUNDLE'] = ""

it will skip the certificate verification
