I just started to learn tensorflow and happened to get through a Future Warning generated by the IPython console.
Here's the block of code:
import tensorflow as tf
x1 = tf.constant(4)
print(x1)
I saved it with the name "hello.py" and executed it on IPython console line by line.
The command gets executed successfully, but ends up with a warning.

In [2]: x1 = tf.constant(4)

I can't understand why am I getting this warning. Is there any way to fix this?
Tensorflow version: 1.10.2
Python IDE: Spyder (Anaconda)
OS: Windows 10 x64
use this command line
pip install h5py==2.8.0rc1
there maybe something wrong with package h5py,just upgrade it can solve your problem

This is my very first experience with sympy. I am usingDEbian bullseye with pythong. I installed git then "git clone https://github.com/sympy/sympy.git" Following that:
abraca#SS:~/SymPy$ python3

>>> from sympy import *
>>> x = symbols('x')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'symbols' is not defined
>>> quit()
What have I done wrong?
Here is what my tree looks like, starting from my root directory:
abraca#SS:~$ ls SymPy/sympy/sympy
abc.py core integrals polys tensor

benchmarks discrete logic sandbox unify
calculus external matrices series utilities
categories functions multipledispatch sets vector
codegen galgebra.py ntheory simplify
combinatorics geometry parsing solvers
concrete holonomic physics stats
conftest.py __init__.py plotting strategies
Installing sympy via git never worked. Here is what did work (note the all important 3, placed after python, not pip):
sudo apt install python3-pip
pip3 install sympy
From then on it all works:

After installing pandas am able to import in cmd as below :

But when am importing pandas in Spyder in IPython 6.5.0 console I get below error:

Please suggest the solution to resolve this issue.I have tried reinstalling the pandas package almost 6-7 times.
I think you should open anaconda command prompt by searching it in windows search bar . Now write there "conda install -c anaconda pandas" and try again to run the program
When I run import keras in the Jupyter Notebook cell, it crashes with the following message:
The kernel appears to have died. It will restart automatically.

Using TensorFlow backend.
Illegal instruction
tensorflow 1.9.0
tensorflow-gpu 1.9.0
tensorflow-tensorboard 1.5.1
The problem was that my obsolete processor did not support AVX. It was necessary to install the version of tensorflow no older than 1.5
I am writing the following code in Jupyter notebook.
import tensorflow as tf
g = tf.Graph()
And I encounter the following error while executing this simple code.
AttributeError: module 'tensorflow' has no attribute 'Graph'
If I execute the same from the console. It works. Any idea what's happening here.
More information:(test is my virtualenv)

Make sure you haven't called any of your python files as 'tensorflow.py'
I resolved this issue by restarting Jupyter Notebook kernel. It's weird.
A simple solution worked for me.
From anaconda navigator first go to environments and create a tensorflow environment like this image
I named it tensorflow. Then from the right select all from the drop down menu and search for tensorflow.
Select it and hit apply. It will download some additional packages along with tensorflow. When you are done, select tensorflow from home and you should be good to go. Here it works.
Check if TensorFlow is installed in Anaconda/Environments. If not, just search and install. Then try to run g=tf.Graph() again. It worked for me.
Note: The example output is an ipython (an enhanced python programming console) feature instead of a python 3 standard (#DTing). One can obtain a list of member functions by dir(libname) command when the default console is used (#Matthew Runchey).
In a python 2.7 console, one has the command libname. to print out member functions of an imported library libname .
The expected output should be something like:
>>> import hashlib
>>> hashlib.
hashlib.algorithms hashlib.new hashlib.sha224 hashlib.sha384
hashlib.md5 hashlib.sha1 hashlib.sha256 hashlib.sha512
(the example is taken from around 0:13 in this video: https://youtu.be/dG3tOsGEYP4 )
However, my python 3.4 console (Win7 x64) gave a syntax error.
>>> import hashlib
>>> hashlib.
File "<stdin>", line 1
hashlib.
^
SyntaxError: invalid syntax
So what is the correct way of doing the same thing in python 3?
dir(module_name)
This prints a list of the functions in whatever you imported.
>>>import hashlib
>>>dir(hashlib)
['__all__', '__builtin_constructor_cache', '__builtins__', '__cached__', '__doc__', '__file__', '__get_builtin_constructor', '__loader__', '__name__', '__package__', '__spec__', '_hashlib', 'algorithms_available', 'algorithms_guaranteed', 'md5', 'new', 'pbkdf2_hmac', 'sha1', 'sha224', 'sha256', 'sha384', 'sha512']
That is not a feature of python, rather an ipython tab completion feature.
