einsum 怎么读

einsum 在英语中的标准读法是 「ine sum」（/ˈaɪnsʌm/）。

Clip of "Einstein summation" — the tensor-contraction primitive in NumPy/PyTorch/JAX (np.einsum, torch.einsum); NumPy docs confirm it "Evaluates the Einstein summation convention on the operands" (docs state the meaning, not the pronunciation). Stress on the first syllable: INE-sum, where "ein" rhymes with the start of Einstein /aɪn/ (like "wine"). Non-native devs commonly say "EEN-sum" (/iːn/) or "AYN-sum" (/eɪn/, as in "rein"); the German "ei" digraph is /aɪ/, not /iː/ or /eɪ/. Non-obvious because the clipped "ein-" hides its origin in the surname Einstein.
