When does this happen?
IF ValueError: Total number of attention heads must be divisible by tensor parallel size when loading a model with tensor parallelism.
How others solved it
THEN Ensure the tensor parallel size is a divisor of the model's num_attention_heads. For example, a model with 32 attention heads supports TP sizes 1, 2, 4, 8, 16, 32. Avoid unsupported sizes like 3, 5, 6, 7.
