Very useful tool!
And how to import the exported model to ollama?

how to import the exported model to ollama?

Just need to do ollama create (model_name) 😎

https://github.com/ollama/ollama/blob/main/docs/import.md

Problem in macos:

OK! I fixed some bugs and make the script support the bash on macOS.

Thanks for your using and reporting! 😄

Now "-" is default.

Simple fix is

FETCH_BLOB_FILE_NAME() {
    echo "${1/:/-}"
}

I'm using the Docker version of Ollama, and I found that running your script has the following error. After analyzing the manifest, I found that the digest is separated by a colon : between the sha and the subsequent string sha:xxx, while in the blobs, it's sha-xxx, which causes the following error:

I modified it and now it works normally:

Oh OK. Because I was using 0.1.29 so I didn't notice that it's already upgraded to be 0.1.42 now.
Wow! Time flies so fast 😎

Upgraded! Thanks for reporting. 😄

@supersonictw thank you.
For Ollama 0.3.4 OLLAMA_HOME must be set to "/usr/share/ollama/.ollama"

"/usr/share/ollama/.ollama"

OK but I need to check it both on Linux and macOS.

Please specify the OLLAMA_HOME variable on your own first, thanks.

I'm a little busy recently... Thanks for your reporting! 😃

A little problem with this script: it can't correctly handle models using Apache 2.0 license(or any other license whose text contains %), because the % character in the license text is not escaped when passing to the printf command.

solved this by escaping the license text first

        LICENSE=$(cat $BLOB_FILE_PATH)
        ESCAPED_LICENSE=$(echo "$LICENSE" | sed 's/%/%%/g')
        printf "$TYPE_NAME \"\"\"$ESCAPED_LICENSE\"\"\"\n" >>"$EXPORT_MODEL_FILE_PATH"
        ;;

./ollama-export qwen2:0.5 excute occur:
./ollama-export.sh: line 86: printf: `)': invalid format character ,but model already exported

./ollama-export qwen2:0.5 excute occur: ./ollama-export.sh: line 86: printf: `)': invalid format character ,but model already exported

try this

@AndersonALAC @cnopens
Oops! 😟
Thanks for your inform that make me realized it might be a security concern due to non-escaped printf.
The new patch already applied! Thanks for reporting again! 🥇

@sokovnich
The patch already applied!
Linux can recognize their OLLAMA_HOME automatically. 🐧

@supersonictw thank you

i got an warning while exporting llava:34b model:
/ollama-export.sh: line 103: warning: command substitution: ignored null byte in input

i inspected the llava model manifest file, and the warning is maybe caused by the mediaType: projector:

{
      "mediaType": "application/vnd.ollama.image.projector",
      "digest": "sha256:83720bd8438ccdc910deba5efbdc3340820b29258d94a7a60d1addc9a1b5f095",
      "size": 699956416
    }

there is no blob file corresponding to the sha256 digest under ollama models/blob folder

Hi, I can use this script to export the model that I have already downloaded using for example "ollama pull" right?
This exported model I can then use to fine tune using LoRA?
I understood that I cannot fine tune using ollama and hence have to export the model, fine tune outside, then import it back to Ollama to use it with ollama inference?

(I am totally new to AI models)

Hello! @vasanthnagkv

This exported model I can then use to fine tune using LoRA?

Yes if the model is llama model based. It's related to ggerganov/llama.cpp#6680

import it back to Ollama to use it with ollama inference

The script can be worked with ollama create for importing, it's compatible.
