Nearest I can go is Heracleum, possibly H. nepalense.
It is a possibility. But Hogweed has papaya like leaves, lobes give palmate shape, here they are pinnatifid.

This is what Flowers of Himalayas (Pollunin and Stainton) writes about H. nepalense: Lower leaves pinnate with toothed, deeply lobed or pinnately cut large leaflets, the upper leaves ternate. A more mature specimen with fully open flowers and fruits could be better interpreted.
