Every TensorFlow CUDA library error — libcublas, libcudart, libnvinfer, cuDNN internal errors, and conda not detecting CUDA — traced to one of four root causes, with the diagnostic order to work through them.
The pandas errors that cost the most time — SettingWithCopyWarning, Int64Index attribute errors, silent assignment failures, and merge row explosions — each traced to the small number of concepts that actually cause them.
