Tests Failing due to SSL verification error.

Issue Summary: SSL Certificate Failures in AutoKeras Tests

Problem AutoKeras tests are failing due to SSL certificate verification errors when downloading datasets and pre-trained model weights from Google Cloud Storage URLs.

Failing Tests

test_structured_data_infer_col_types - Titanic dataset download test_resnet_pretrained_build_return_tensor - ResNet50 weights test_resnet_pretrained_with_one_channel_input - ResNet50 weights test_xception_pretrained_build_return_tensor - Xception weights test_xception_pretrained_with_one_channel_input - Xception weights test_greedy_oracle_populate_doesnt_crash_with_init_hps - EfficientNet weights Root Cause [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate

Proposed Solution

Replace network downloads with pre-bundled local files:

Add titanic_train.csv and titanic_test.csv Add models directory with ResNet50, Xception, and EfficientNet weights Modify test_utils.py to use local paths instead of downloads Impact All tests pass offline without network dependencies or SSL workarounds.
