Getting: AttributeError: 'BertTokenizer' object has no attribute 'encode'
# 🐛 Bug

## AttributeError: 'BertTokenizer' object has no attribute 'encode'

Model, I am using Bert

The language I am using the model on English

The problem arises when using:
```
    input_ids = torch.tensor([tokenizer.encode("raw_text", add_special_tokens=True)]) 
```

The tasks I am working on is:

##Text Summary for the following paragraph of text 
 <code>
"['26The Indian organic market\nhave begun to disrupt the market with their one-of-a-kind \nofferings.', 'In an effort to promote a healthier lifestyle, these \n\nplayers are playing a pivotal role by providing consumers with \n\nwholesome organic produce.', 'Since the organic food segment is still at a nascent stage \nin India, both the Government and private players need \n\n\n\ninvolved.', 'The organic farming industry in India holds immense \n\npotential to grow, provided it receives steady investment \n\n\n\nlike incentivizing organic cultivation, food processing, \n\n\n\nof the challenges faced by the organic sector today can be \n\ngrouped into three heads:\n\nŁ \n\nlengthy procedures, international validity, inadequate \ncertifying agencies and inadequate supporting infrastructure \n\n\n\n\ncost of internal audits and documentation is approximately \n\n\n\nreduced, it is expensive for many small groups of farmers or \nindividual farmers.', 'Ł \nThere is also a gap in the \n\nrequirements.', 'Additionally, key trading partners have \ntraditionally demonstrated a lack of willingness to sign \n\nequivalence arrangements.', 'Ł \nThe \n\n\nprocess of the farm or crop cannot be placed in the organic \n\n\nharvest is sold as conventional crops, thereby causing the \nfarmer to incur a loss.', 'Ł \ncommodities: \nDairy products have a different standard while \nmeat has a different standard .', 'The process of standardization \n\nof organic coconut will be different from that of the value-\n\nadded products of coconut.', 'Therefore, a company having \n\nand maintain multiple records as per the applicable standards.', 'Ł \n\nnumber of producers in the world yet they cultivate less than \n1% of the organic area.', 'The conventional production system is \nmore lucrative given the land fragmentation.', 'Ł Lack of incentives for farmers: \nThe transition from \n\nconventional to organic farming is accompanied by high \ninput costs and low yields in the initial years.', 'The cost of \ngoing completely organic is quite high, due to the high cost \n\nof organic manure.', 'The commercially available bio-manure \nproducts may not be completely organic, and therefore the \n\n\nThis is one of the many reasons why farmers are skeptical \nwhen it comes to shifting from conventional to organic \nfarming.', 'In such cases, the farmers choose to play it safe by \n\npracticing conventional methods of farming.', 'Ł Lack of standardized organic agriculture inputs and subsidy \non organic inputs:\n Farmers also face an acute shortage of \nquality standardized organic agriculture inputs, which are \noften much more expensive than conventional agricultural \n\ninputs.', 'There are no subsidies from the Government on \nagriculture inputs, especially biofertilizers and biopesticides, \nmaking the cost of cultivation for organic farming quite high.', 'Unless the farmers use their own farm grown manure in \nlarge quantities, they are unable to meet the expenses.', 'Lack \nof proper organic inputs often results in low yield making \n\norganic farming unsustainable for the farmers.', 'Ł Lack of organic cultivation research and extension: \nThe \n\ncurrent research and extension on organic farming are much \nlesser than that on conventional farming.', 'There is a lack of \n\n\nStrong government support for producing non-GMO

are very limited for organic, for example, the ATMA \nscheme focuses more on conventional farming.', 'There is no \n\ntimely advisory available for organic pest and disease control \n\nmeasures.', 'Processor-level challenges\nŁ Supply chain issues: \nMany farmers are apprehensive of \n\norganic farming since it involves high production costs.', 'The emphasis on collection, transportation and storage of \nfresh organic produce is very high.', 'Due to relatively low \n\nvolumes, the marketing and distribution chain of organic food \n\nvery high.', 'For example, organic produce cannot be stored in \n\ngovernment warehouses that practice chemical treatment of \nstorage areas.', 'High demand and low supply further create \n\n\nthese products have higher price markups than conventional \nproducts.', 'Additionally, many sellers mix the produce from \ndifferent geographical regions to help attain a competitive \n\nprice, thus compromising the geographical origin norm.', 'Ł Lack of a proper organic supply chain is felt more acutely in \n\nhilly, tribal and remote areas that have a high potential for \n\ninfrastructure.', 'Ł Global competitiveness:\n A major challenge India faces is \n\nthat of increasing its share in the global organic food export \nmarket, in lieu of global competitiveness.', 'There often exists a \ndichotomy between international quality and safety standards \n\nand Indian organic stands, which puts Indian produce at a \ndisadvantage.', 'Ł Lack of proper branding and packaging: \n\nof organic products require separate packing material that is \nnatural and requires distinctive branding that distinguishes \norganic from conventional products.', 'At present, there is \n\nan absence of regulations on labeling standards.', 'There is

## To reproduce

Steps to reproduce the behavior:

1. In the first Imported torch 
```Python
import torch
from pytorch_pretrained_bert import BertTokenizer, BertModel, BertForMaskedLM
import logging
```
2. defined models : 
```
MODELS = [(BertModel,       BertTokenizer,       'bert-base-uncased') ] 
```
3.
```
# Let's encode some text in a sequence of hidden-states using each model:
for model_class, tokenizer_class, pretrained_weights in MODELS:
    # Load pretrained model/tokenizer
    tokenizer = tokenizer_class.from_pretrained(pretrained_weights)
    model = model_class.from_pretrained(pretrained_weights)
```
4. If I am trying to encode with following code 
```
    # Encode text
   <code> input_ids = torch.tensor([tokenizer.encode("raw_text", add_special_tokens=True)])  # Add special tokens takes care of adding [CLS], [SEP], <s>... tokens in the right way for each model.
    with torch.no_grad():
        last_hidden_states = model(input_ids)[0]
```
I am getting following error 
```

      3 with torch.no_grad():
      4     last_hidden_states = model(input_ids)[0]  # Models outputs are now tuples

AttributeError: 'BertTokenizer' object has no attribute 'encode'
```
## Expected behavior
Tokenization should get completed
