I have my data in a (93894, 8320) numpy array. All good so far. When I go to np.concatenate it with another array that's (93894, 1), it crashes Colab every single time, even though it's handled the larger tasks just fine.
model_data = np.concatenate((model_data_minus_labels, all_labels), axis=1)
I've switched to high-RAM runtime, tried switching from CPU to GPU and back, and am using Colab Pro.
