I created a virtual environment for python2.7 and I installed caffe using the command conda install -c conda-forge caffe. But when I try to import caffe, its throwing the following error.
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

ImportError: libopencv_highgui.so.3.3: cannot open shared object file: No such file or directory
Can anyone tell me how to resolve this error?
The package info after I installed caffe (if this info is useful to debug)

Did I import the wrong version of TensorFlow?
i try to install my website on a webserver which is in CentOS 7 with Django 2.0.6 and Python 3.6.
I installed : mysql-connector = 2.1.6,
mysql-connector-python = 8.0.11,
MySQL-python = 1.2.5,
mysqlclient = 1.3.12,
PyMySQL = 0.8.1
And when i run this command :
python3.6 manage.py migrate
I have this error :
File "MYPYTHONPATH/python3.6/site-packages/django/db/backends/mysql/base.py", line 36, in <module>
raise ImproperlyConfigured("mysqlclient 1.3.3 or newer is required; you have %s" % Database.__version__)
django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.3 or newer is required; you have 1.2.5
But in the base.py file :
try:
import MySQLdb as Database
except ImportError as err:
raise ImproperlyConfigured(
'Error loading MySQLdb module.\n'
'Did you install mysqlclient?'
) from err
from MySQLdb.constants import CLIENT, FIELD_TYPE # isort:skip

version = Database.version_info
if version < (1, 3, 3):
raise ImproperlyConfigured("mysqlclient 1.3.3 or newer is required; you have %s" % Database.__version__)
I dont understand what can i do for resolving this kind of problem !
I hope someone can help me on =)
Okay, i solved it with the answer of this thread.
No module named MySQLdb
pip install PyMySQL
and then add this two lines to your Project/Project/init.py
import pymysql
pymysql.install_as_MySQLdb()
Works on WIN and python 3.3+

I got a similar post on Stack Overflow : can't pip install mysql-python
That is for Ubuntu. But still I tried to install python-dev as suggested in the answer of that post using pip and got the following error :

Thanx in advance!!
python-dev is the wrong python-dev; it seems some rogue Chineeze took the name and created a package that installs a backdoor.
Real python-dev is a development package for Debian/Ubuntu installable with apt. You don't need it in MacOS. If you have done brew install python (or python3) you should already have all necessary development files.

I successfully installed NLTK 2.0.4, but when I tried to download the NLTK packages, i.e.
nltk.download('stopwords')
it doesn't work, so I am trying to install an updated version of NLTK for python 3 but it gives this error:

Is there any way to install NLTK for python33?
First install python3-pip then use it to install pyyaml
$ sudo apt-get install python3-pip
$ sudo pip3 install pyyaml
$ wget http://www.nltk.org/nltk3-alpha/nltk-3.0a3.tar.gz
$ tar -xzvf nltk-3.0a3.tar.gz
$ cd nltk-3.0a3/
$ sudo python3 setup.py install
