I'm trying to import QHash class from PyQt5.QtCore but no luck.
I got an error
AttributeError: module 'PyQt5.QtCore' has no attribute 'QHash'
Could anyone know how to do it?
Thanks a lot.

I tried the below line of code, but it is giving me the below error
y = rnn_cell_impl._linear(slot_inputs, attn_size, True)
AttributeError: module 'tensorflow.python.ops.rnn_cell_impl' has no attribute '_linear'
I am currently using Tensorflow version 2.10, I tried with all possible solutions by using
#from tensorflow.contrib.rnn.python.ops import core_rnn_cell
or
#from tensorflow.keras.layers import RNN
still no solution.
Can someone help me with the same?
I have imported norm as:
from scipy.stats import norm
I want to find out the version using:
print(scipy.__version__)
but it is raising an error called:
NameError: name 'scipy' is not defined
if i am using this:
print(norm.__version__)
but it is raising another error called:
AttributeError: 'norm_gen' object has no attribute '__version__'
Please help me to solve this issue.
Thanks
The line from scipy.stats import norm doesn't make the name scipy available in your current namespace. To use scipy.__version__, you must first import scipy.
In [57]: import scipy
In [58]: print(scipy.__version__)

Why doesn't accessing unittest.mock.patch throw an attribute error when I import testfixtures in the below code?
I myself suspect that it is because testfixtures might be importing unittest.mock somewhere internally however, is there any way I could change this behavior if I want unittest.mock to always be imported explicitly and get an AttributeError otherwise?
import unittest
import sys
import os
import testfixtures
class Test(unittest.TestCase):
#unittest.mock.patch('sys.version_info', (2,7,0))
def test_version(self):
assert(sys.version_info < (3,0,0))
Accessing unitest.mock without importing it should throw an AttributeError but that's not the case when testfixtures is imported.
I saw this statement
from django import forms
the folder structure is
django\
__init__.py
forms\
__init__.py
..(continues)
My doubt is instead of the above statement why cant we imports forms like this.
import django.forms
when i tried this in pycharm. it says unused import statement.
the following is my code:
#from django import forms
import django.forms
from .models import Post
class PostForm(forms.ModelForm):
class Meta:
model = Post
fields = ('title', 'text',)
it gives me error
class PostForm(forms.ModelForm):
NameError: name 'forms' is not defined
From python's docs,
... when using syntax like import item.subitem.subsubitem, each item
except for the last must be a package; the last item can be a module
or a package but can’t be a class or function or variable defined in
the previous item.
Then since its __init__.py designates forms as a package, you should be able to import it via import django.forms. Accessing its members will be different since where before you wrote forms.x now you would write django.forms.x.
I have a python project that do the following import
from PyQt4 import QtGui, QtCore
I would like to change the cursor's shape at certain point, for example, I would create a new QCursor object
self.cursor_oh = QCursor()
self.cursor_oh.setShape()
most documentation and searches I did indicate to just set the shape using enum type such as:
Qt.OpenHandCursor
But, such enum is not recognized and it always results in the following error message:
AttributeError: 'module' object has no attribute 'OpenHandCursor'
So, what am I missing here?
Apparently, the Qt namespace is under QtCore, so by adding the QtCore qualifier, it found all of the Qt cursor types.
I haven't tried this in PyQt4 but in PyQt6 it has to be:
QtCore.Qt.CursorShape.OpenHandCursor
