How do I get all tokens in a AutoTokenizer?
Output
There are a few ways to get all tokens in an AutoTokenizer:
1. Using the `get_vocab()` method:
| from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
vocab = tokenizer.get_vocab() # Returns dict of {token: token_id}
# Get all tokens
all_tokens = list(vocab.keys())
|
2. Using the `vocab` property (if available):
| tokens = list(tokenizer.vocab.keys())
|
3. Converting token IDs to tokens:
| # Get tokens by converting all possible token IDs
vocab_size = tokenizer.vocab_size
all_tokens = [tokenizer.convert_ids_to_tokens(i) for i in range(vocab_size)]
|
4. Using `tokenizer.all_special_tokens` to get just the special tokens:
| special_tokens = tokenizer.all_special_tokens
|

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
# Get vocabulary
vocab = tokenizer.get_vocab()
# Get all tokens
all_tokens = list(vocab.keys())
# Print first 10 tokens
print("First 10 tokens:", all_tokens[:10])
# Print vocabulary size
print("Vocabulary size:", len(all_tokens))
# Get special tokens
special_tokens = tokenizer.all_special_tokens
print("Special tokens:", special_tokens)

Note that different tokenizer implementations might have slightly different methods available, but `get_vocab()` is generally the most reliable way to get all tokens.

Output
There are a few ways to get all tokens in an AutoTokenizer. Here are the main methods:
1. Using get_vocab():
| from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
vocab = tokenizer.get_vocab() # Returns dictionary of {token: token_id}
# Get all tokens
all_tokens = list(vocab.keys())
|
2. Using vocab_dict or vocab property (not available for all tokenizers):
| # For some tokenizers
all_tokens = list(tokenizer.vocab.keys())
|
3. Using the conversion from ids:
| # Get tokens by converting all possible ids
vocab_size = tokenizer.vocab_size
all_tokens = [tokenizer.convert_ids_to_tokens(i) for i in range(vocab_size)]
|
4. For special tokens specifically:
| # Get special tokens
special_tokens = tokenizer.all_special_tokens
|

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
# Get complete vocabulary
vocab = tokenizer.get_vocab()
all_tokens = list(vocab.keys())
# Print some information
print(f"Vocabulary size: {len(vocab)}")
print(f"First 10 tokens: {all_tokens[:10]}")
print(f"Special tokens: {tokenizer.all_special_tokens}")
|
Note:
- Different tokenizer types might have slightly different methods to access their vocabulary
- The get_vocab() method is the most reliable way across different tokenizer types
- The vocabulary includes regular tokens and special tokens
- Some tokens might appear as weird characters or subwords, which is normal for subword tokenizers

|
3. Using all_special_tokens and vocab:
| tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
# Get both regular tokens and special tokens
all_tokens = list(tokenizer.get_vocab().keys())
special_tokens = tokenizer.all_special_tokens
all_tokens_with_special = all_tokens + special_tokens
|
Note that the exact tokens will depend on the specific model/tokenizer you're using. Different models use different vocabularies and tokenization schemes.
Example with counts:
| tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
vocab = tokenizer.get_vocab()
print(f"Vocabulary size: {len(vocab)}")
print(f"Number of special tokens: {len(tokenizer.all_special_tokens)}")
print("\nFirst 10 tokens:")
for token in list(vocab.keys())[:10]:
print(f"{token}: {vocab[token]}")

1. Using get_vocab():
| from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
vocab = tokenizer.get_vocab() # Returns dictionary of token: id pairs

2. Using vocab_size and convert_ids_to_tokens():
| tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
all_tokens = [tokenizer.convert_ids_to_tokens(i) for i in range(tokenizer.vocab_size)]
|
3. If the tokenizer has a direct vocab attribute:
| tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased")
if hasattr(tokenizer, 'vocab'):
all_tokens = list(tokenizer.vocab.keys())
|
Note that different tokenizer implementations might have slightly different ways to access their vocabulary. The get_vocab() method is generally the most reliable approach as it's standardized across different tokenizer types.

vocab = tokenizer.get_vocab()
all_tokens = list(vocab.keys())
# Print first 10 tokens
print("First 10 tokens:", all_tokens[:10])
print("Vocabulary size:", len(all_tokens))
|
This will give you access to all tokens in the tokenizer's vocabulary.

# Convert IDs to tokens
all_tokens = [tokenizer.convert_ids_to_tokens(id) for id in all_token_ids]
|
4. For specific special tokens:
| # Get just special tokens
special_tokens = tokenizer.all_special_tokens
# Get special token IDs
special_token_ids = tokenizer.all_special_ids
|
The first method using get_vocab() is generally the most reliable and recommended approach since it returns the complete vocabulary as a dictionary mapping tokens to their IDs.
