**Rating:** 2.5/5.0 stars

**Reviewed by:** Etienne P. | Senior Machine Learning Engineer, Small-Business (50 or fewer emp.)

**Reviewed Date:** July 14, 2021

**What do you like best about Chainer?**

imperative programming. cupy was visionnary.

**What do you dislike about Chainer?**

nothing, but pytorch ecosystem grew very fast and i started using it instead

**Recommendations to others considering Chainer:**

i would need to have a fresh look at it...

**What problems is Chainer solving and how is that benefiting you?**

all of what i did with pytorch i could have done it with chainer most probably. i am not sure if there is also a chainer.DataLoader.
