Offline mode tutorial: where is the "offline environment" and how to Create a "virtual environment"?

[kucingkembar]

hi, sorry for my bad English, and I am quite a newbie
I am quite confused with the offline tutorial
"Now, move everything in the dlt directory to your offline environment. Create a virtual environment:"
-where is the "offline environment"?
and
-how to Create a "virtual environment"?
I using windows 11 and python 3.9

Offline environment means where you want to use your model without internet access. So maybe in PC A, you have internet and you can download dl-translate and other pip packages. Then you transfer the content of your folder via a USB key to PC B, where you don't have internet.

You can find out instructions on virtualenvs with this quick search query. The first result shows you how to create a virtual env.

thank you for the reply xhlulu,

1. is there any default "virtual environment" in windows 10?, or I must create it?
2. if I must create it, can you make the bat or ps1 script?
3. can you provide the links to the offline data? i download via python script always stuck at teens percentage
4. sorry if this is out of topic, if I need online for translation, why does this "mt = dlt.TranslationModel()" load so many resources to the RAM?

You must create it. I don't usually use Windows so i'm not aware of the best practices, but it's something you should be able to find on Google.

The instructions in the readme is the only way I am aware for downloading the weights and libraries to run this offline. You might need a more stable or faster internet connection - there's many GBs of files to download.

This uses a quite large multilingual model, which takes a lot of memory, whether it's running on CPU or GPU. If you can't allow that locally, you might want to look into external hosting services (Huggingface, GCP, AWS, etc.)

thank you again for the reply xhlulu,
I will stick to online mode,

anyway
is there any change in the future you will only use 2 languages instead of 50 languages at once?
I think it will cut down 48/50 data needed to load to RAM
something like this:

import dl_translate as dlt
mt = dlt.TranslationModel(source=dlt.lang.HINDI, target=dlt.lang.ENGLISH)
text_hi = "संयुक्त राष्ट्र के प्रमुख का कहना है कि सीरिया में कोई सैन्य समाधान नहीं है"
mt.translate(text_hi)

I've thought about adding bilingual models from MarianNMT (they have a few hundred models for two-directions and are much smaller). However this is already covered by easynmt, which was created at the same time as this library and now also uses huggingface in the backend. They also have a neat implementation for bilingual models so definitely recommend checking it out.

thank you xhlulu for the reply,
I am very satisfied with the answer
