Known Issues

Heavily memory and CPU usage

• TabNine’s local deep learning completion might be enabled by default. It is very CPU-intensive if your device can’t handle it. You can check by typing “TabNine::config” in any buffer (your browser should then automatically open to TabNine’s config page) and disable Deep TabNine Local (you will lose local deep learning completion). More details here.

ICON displayed error

If candidate icons of tabnine displayed unnormally capf icon error, try set kind-icon-mapping for tabnine:

• With all-the-icons

(add-to-list 'kind-icon-mapping '(tabnine "ai" :icon "cloud" :face shadow) t)

• With all-the-icons-nerd-fonts

(add-to-list 'kind-icon-mapping `(tabnine ,(nerd-icons-codicon "nf-cod-hubot") :face font-lock-warning-face) t)
