I'm using the latest version of the "Deep learning on images." When running the macro to install a pretrained model we get the following error:

    Hi @brian-walheim

    Considering there is "SSL: CERTIFICATE_VERIFY_FAILED" while accessing storage.googleapis.com there are two possible root causes:

    • OS truststore has missing ROOT CA certs that can validate certs signed by Google Trust Services LLC
    • there is an HTTP_PROXY in your env that interfere with SSL certs.

    You will need to work with your sysadmin/network team to fix that. You can check that you can successfully connect to this site with the next CLI command: 

    curl -vvv https://storage.googleapis.com

    Getting HTTP/1.1 400 Bad Request is fine but if you get SSL verification failed -> something environmental on your side.

    I tried the curl command and got the following output

    Hi @brian-walheim

    Thanks for the test. So this indeed confirmes that that SSL cert in your proxy has expired. Notice the issuer:

    issuer: E=acsgmgmt@ngc.com,CN=Northrop Grumman Proxy CA,O=Northrop Grumman,L=McLean,C=us
    * NSS error -8162 (SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE)
    * The certificate issuer's certificate has expired.

    While here is the example what it should be like: 

    curl -vvv https://storage.googleapis.com
* About to connect() to storage.googleapis.com port 443 (#0)
*   Trying 74.125.193.128...
* Connected to storage.googleapis.com (74.125.193.128) port 443 (#0)
* Initializing NSS with certpath: sql:/etc/pki/nssdb
*   CAfile: /etc/pki/tls/certs/ca-bundle.crt
  CApath: none
* SSL connection using TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
* Server certificate:
*   subject: CN=storage.googleapis.com
*   start date: May 30 11:27:43 2022 GMT
*   expire date: Aug 22 11:27:42 2022 GMT
*   common name: storage.googleapis.com
*   issuer: CN=GTS CA 1C3,O=Google Trust Services LLC,C=US
