googletrans stopped working with error 'NoneType' object has no attribute 'group'

Python

Python Problem Overview

I was trying googletrans and it was working quite well. Since this morning I started getting below error. I went through multiple posts from stackoverflow and other sites and found probably my ip is banned to use the service for sometime. I tried using multiple service provider internet that has different ip and stil facing the same issue ? I also tried to use googletrans on different laptops , still same issue ..Is googletrans package broken or something google did at their end ?

>>> from googletrans import Translator
>>> translator = Translator()
>>> translator.translate('안녕하세요.')

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    translator.translate('안녕하세요.')

Python Solutions

Solution 1 - Python

Update 06.12.20: A new 'official' alpha version of googletrans with a fix was released

Install the alpha version like this:

pip install googletrans==3.1.0a0

Translation example:

translator = Translator()
translation = translator.translate("Der Himmel ist blau und ich mag Bananen", dest='en')
print(translation.text)
#output: 'The sky is blue and I like bananas'

In case it does not work, try to specify the service url like this:

from googletrans import Translator
translator = Translator(service_urls=['translate.googleapis.com'])
translator.translate("Der Himmel ist blau und ich mag Bananen", dest='en')

See the discussion here for details and updates: https://github.com/ssut/py-googletrans/pull/237

Update 10.12.20: Another fix was released

As pointed out by @DesiKeki and @Ahmed Breem, there is another fix which seems to work for several people:

pip install googletrans==4.0.0-rc1

Github discussion here: https://github.com/ssut/py-googletrans/issues/234#issuecomment-742460612

In case the fixes above don't work for you

If the above doesn't work for you, google_trans_new seems to be a good alternative that works for some people. It's unclear why the fix above works for some and doesn't for others. See details on installation and usage here: https://github.com/lushan88a/google_trans_new

#pip install google_trans_new

from google_trans_new import google_translator  
translator = google_translator()  
translate_text = translator.translate('สวัสดีจีน',lang_tgt='en')  
print(translate_text)
#output: Hello china

Solution 2 - Python

Update 01/12/2020: This issue re-emerged lately, (apparently) caused once again by some changes on the Google translation API.

A solution is being discussed (again) in this Github issue. Although there is not a definitive solution yet a Pull Request seem to be solving the problem: https://github.com/ssut/py-googletrans/pull/237.

While we wait for it to be approved it can be installed like this:

$ pip uninstall googletrans
$ git clone https://github.com/alainrouillon/py-googletrans.git
$ cd ./py-googletrans
$ git checkout origin/feature/enhance-use-of-direct-api
$ python setup.py install

Original Answer:

Apparently it's a recent and widespread problem on Google's side. Quoting various Github discussions, it happens when Google sends you directly the raw token.

It's being discussed right now and there is already a pull request to fix it, so it should be resolved in the next few days.

For reference, see:

https://github.com/ssut/py-googletrans/issues/48 <-- exact same problem reported on the Github repo https://github.com/pndurette/gTTS/issues/60 <-- seemingly same problem on a text-to-speech library https://github.com/ssut/py-googletrans/pull/78 <-- pull request to fix the issue

To apply this patch (without waiting for the pull request to be accepted) simply install the library from the forked repo https://github.com/BoseCorp/py-googletrans.git (uninstall the official library first):

$ pip uninstall googletrans
$ git clone https://github.com/BoseCorp/py-googletrans.git
$ cd ./py-googletrans
$ python setup.py install

You can clone it anywhere on your system and install it globally or while inside a virtualenv.

Solution 3 - Python

Try google_trans_new. It solved the problem for me https://github.com/lushan88a/google_trans_new

> pip install google_trans_new

from google_trans_new import google_translator  
  
translator = google_translator()  
translate_text = translator.translate('Hola mundo!', lang_src='es', lang_tgt='en')  
print(translate_text)
-> Hello world!

Solution 4 - Python

Update 10.12.20: New Alpha Version Release (Stable Release Candidate) is released: 4.0.0-rc1

It can be installed as follows:

pip install googletrans==4.0.0-rc1

Usage:

translation = translator.translate('이 문장은 한글로 쓰여졌습니다.', dest='en')
print(translation.text)
>>This sentence is written in Korean.
detected_lang = translator.detect('mein english me hindi likh raha hoon')
print(detected_lang)
>>Detected(lang=hi, confidence=None)
detected_lang = translator.detect('이 문장은 한글로 쓰여졌습니다.')
print(detected_lang)
>>Detected(lang=ko, confidence=None)

Solution 5 - Python

Updated Answer as of 2021 Sept

pip uninstall googletrans==4.0.0-rc1

pip install googletrans==3.1.0a0

The 3.1.0a0 version works with bulk translation too!

Solution 6 - Python

Here is an unofficial fix to this problem as Darkblader24 stated in: https://github.com/ssut/py-googletrans/pull/78

Update gtoken.py like this:

    RE_TKK = re.compile(r'TKK=eval\(\'\(\(function\(\)\{(.+?)\}\)\(\)\)\'\);',
                        re.DOTALL)
    RE_RAWTKK = re.compile(r'TKK=\'([^\']*)\';',re.DOTALL)

    def __init__(self, tkk='0', session=None, host='translate.google.com'):
        self.session = session or requests.Session()
        self.tkk = tkk
        self.host = host if 'http' in host else 'https://' + host

    def _update(self):
        """update tkk
        """
        # we don't need to update the base TKK value when it is still valid
        now = math.floor(int(time.time() * 1000) / 3600000.0)
        if self.tkk and int(self.tkk.split('.')[0]) == now:
            return

        r = self.session.get(self.host)

        rawtkk = self.RE_RAWTKK.search(r.text)
        if rawtkk:
            self.tkk = rawtkk.group(1)
            return

Solution 7 - Python

By the time of this answer, you can solve it with the following:

Uninstall your installed version of

pip uninstall googletrans

Install the following version

pip install googletrans==4.0.0rc1

I hope this will works for you as it worked for me.

You can try it now:

from googletrans import Translator
translator = Translator()
ar = translator.translate('مرحبا').text
print(ar)

Solution 8 - Python

This worked for me:

pip install googletrans==4.0.0-rc1

Original answer can be found here: https://github.com/ssut/py-googletrans/issues/234#issuecomment-742460612

Solution 9 - Python

pip uninstall googletrans googletrans-temp
pip install googletrans-temp

Worked for me in Win10 and Ubuntu 16 (Python 3.6) as of 2019.2.24 -- Refer to one of the replies in https://github.com/ssut/py-googletrans/issues/94. The old fix pip install git+https://github.com/BoseCorp/py-googletrans.git --upgrade does not work any more over here.

Solution 10 - Python

Fixed is here https://pypi.org/project/py-translator/

$ pip3 install py_translator==1.8.9

from py_translator import Translator
s = Translator().translate(text='Hello my friend', dest='es').text
print(s)

> out:Hola mi amigo

Solution 11 - Python

googletrans is not supported in latest python so you need to unistall it

install new googletrans ( pip install googletrans==3.1.0a0)

Solution 12 - Python

Making the following change to gtoken made it work for me:

RE_TKK = re.compile(r'tkk:\'(.+?)\'')      

def __init__(self, tkk='0', session=None, host='translate.google.com'):
    self.session = session or requests.Session()
    self.tkk = tkk
    self.host = host if 'http' in host else 'https://' + host

def _update(self):
    """update tkk
    """
    # we don't need to update the base TKK value when it is still valid
    r = self.session.get(self.host)        
    
    self.tkk = self.RE_TKK.findall(r.text)[0]
    
    now = math.floor(int(time.time() * 1000) / 3600000.0)
    if self.tkk and int(self.tkk.split('.')[0]) == now:
        return

    # this will be the same as python code after stripping out a reserved word 'var'
    code = unicode(self.RE_TKK.search(r.text).group(1)).replace('var ', '')
    # unescape special ascii characters such like a \x3d(=)

I obtained this snippet from the ticket here.

Note that this is slightly different from other change suggested earlier by Kerem.

For other uninitiated folks like me, gtoken.py can be found within AppData\Local\Continuum\anaconda3\site-packages\googletrans on a Windows machine using Anaconda. To find AppData, go into the address bar in file explorer, type '%AppData%', and hit Enter.

Solution 13 - Python

It turns out putting the call whithin a try/except block solved the problem for me

try:
    langs = translator.detect(update.message.text)
    if langs.lang == 'en':
        foo(translator.translate(update.message.text,dest='zh-cn').text)
    else:
        bar(translator.translate(update.message.text,dest='en').text)
except Exception as e:
    print(e)

Solution 14 - Python

This is how I fixed my problem.

pip3 uninstall googletrans
pip3 install googletrans==3.1.0a0

First you need to uninstall the previous version and the install the 3.1.0 version.

Solution 15 - Python

Use the translators package from here

  1. It works (;
  2. Supports more then google

Installation:

... pip install translators --upgrade

Usage:


    >>> import translators as ts
    Using Israel server backend.
    >>> ts.google('שלום' , to_language = 'es')
    'Hola'
