+Tokenized (Llama 2) verison of [NousResearch/dolma-v1_7-30B](https://huggingface.co/datasets/NousResearch/dolma-v1_7-30B) as a [Nanotron](https://github.com/huggingface/nanotron) dataset split into 10 GB chunks.
+
+To download:
+```shell
+huggingface-cli download --repo-type dataset --local-dir dolma-v1_7-30B-tokenized-llama2-nanoset --local-dir-use-symlinks False NousResearch/dolma-v1_7-30B-tokenized-llama2-nanoset
+```
+
+To recombine:
+```shell
+cat dolma-v1_7-30B-tokenized-llama2-nanoset_input_ids.npy.* > dolma-v1_7-30B-tokenized-llama2-nanoset_input_ids.npy
+rm -rf dolma-v1_7-305B-tokenized-llama3-nanoset
+```
+
+Can also be used directly with numpy, for example
+```python
+import numpy as np
+
+dataset_buffer_mmap = np.memmap("dolma-v1_7-30B-tokenized-llama2-nanoset_input_ids.npy",
+  mode="r", order="C", dtype=np.int32)
+dataset_buffer = memoryview(dataset_buffer_mmap)
+dataset_number_of_tokens = int(len(dataset_buffer))
+```
