Why people look for alternatives to Calvin
The complaints that come up most often in public discussion — reviews, forums and community threads. Not our opinion, and not the vendor's marketing.
- Dataset download is 517GB with slow speeds and frequent corruption.
- EGL setup on Ubuntu is error-prone, 'failed to EGL with glad'.
- Documentation on data collection is sparse and confusing.
- Training can get stuck, with iterations taking ~24 seconds each.
