Failures when using PyTorch local build vs. binaries #1134
Description
🐛 Describe the bug
I ran into an issue with loading the tokenizer, which was root caused to me using my local PyTorch build.
After building the aoti runner, I ran the following command: cmake-out/aoti_run exportedModels/stories15M.so -z /home/angelayi/.torchchat/model-cache/stories15M/tokenizer.model -i "Once upon a time”
With my local build, the above command ran into the error: couldn't load /home/angelayi/.torchchat/model-cache/stories15M/tokenizer.model which is from the sentencepiece tokenizer. Specifying -l 2 doesn't change anything as this is the default setting.
Changing to -l 3 results in the following error:
terminate called after throwing an instance of 'std::invalid_argument'
what(): invalid encoder line:
zsh: IOT instruction (core dumped) cmake-out/aoti_run ../lucy_stories15M.so -z ../tokenizer.model -l 3 -i
After re-running ./install/install_requirements.sh, this installs PyTorch version at 08142024, and runs successfully.
So I tried today's nightly (09112024) using pip3 install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cu121, and this also runs successfully.
Going back to my local PyTorch build, I checked out the commit 26e5572 which corresponds to the cutoff of today's nightly, and built PyTorch locally. This runs into the initial error with the tokenizers.
I still didn't figure out how to run with my local PyTorch build, but quoting Nikita, this is motivation to create a docker/venv story :P
