Is using pip install shopifyAPI for python module causing errors?

[rikutonakamura7]

I am getting multiple variants as follows

I'm using pip install shopifyAPI

variant_ids = "342523524,24535242,...."
shopify_variants = shopify.Variant.find(ids=variant_ids, limit)

Sometimes it works, sometimes it doesn't. 

Is this correct? Or is it a source of error?
