## Running TimesFM on the benchmark
|
||||
|
||||
Install the environment and the package as detailed in the main README and then follow the steps from the base directory.
|
||||
We need to add the following packages for running these benchmarks. Follow the installation instructions till before `poetry lock`. Then,
|
||||
|
||||
```
|
||||
conda activate tfm_env
|
||||
TF_CPP_MIN_LOG_LEVEL=2 XLA_PYTHON_CLIENT_PREALLOCATE=false python3 -m experiments.long_horizon_benchmarks.run_eval \

||||
--model_path=<model_path> --backend="gpu" \
|
||||
poetry add git+https://github.com/awslabs/gluon-ts.git
|
||||
poetry add git+https://github.com/amazon-science/chronos-forecasting.git
|
||||
poetry lock
|
||||
poetry install --only pax
|
||||
```
|
||||
Note that for now only the pax version runs on this benchmark, because we had to remove the old tf dependency from the pytorch version. We will fix this issue soon.
|
||||
|
||||
To run the timesfm on the benchmark do:
|
||||
|
||||
```
|
||||
poetry run python3 -m experiments.long_horizon_benchmarks.run_eval \
|
||||
--model_path=google/timesfm-1.0-200m --backend="gpu" \
