I used to use Anaconda 4.3.1 (64-bit) along with Python 3.6.0 and have written several codes and all of them worked fine. I also used Jupyter (Notebook Server 5.0.0) and Spyder too. They all work and my codes were able to run correctly. After recent updates on Anaconda, Spyder and Python all my recent Python codes (those worked before the updates) are not working.
Any Suggestions?
Could you please let me know how I can go back to Anaconda 4.3.1 with Python 3.6.0?
Thank you in advance for an early reply.
Best Regards
I uninstalled and did fresh installation of Anaconda a few times but no
changed with same errors.
Please see below for the error messages:

matplotlib should plot the figure without any issues.

I'm having serious problems with wandb on a nVidia pytorch image using arm64 architecture. No info online on how to solve this problem. Cannot even start a project with wandb.init()

It seems wandb hasn't been installed correctly in your case.
I am having a problem as i upload my model in drive and mount it in Colab module imports are working fine in previous cell as i gave the root path and sys.append() it , I am using (tf.compat.v1) you can see it in ouptut, but still getting this error also tried (tensorflow v2) and used tf.io.gfile but still same error. Kindly help me

Try to downgrade TF 1.15 from TF 2.x, your issue will be resolved.
Please refer code as shown below
!pip uninstall tensorflow
!pip install tensorflow==1.15
import tensorflow as tf
If you are looking for simple solution for Colab, please use %tensorflow_version 1.x magic command, which does for you without un-installation.
%tensorflow_version 1.x
import tensorflow as tf
I am using python 3.7, plotly 3.8.1 and cufflinks 0.15 and got the below error, please kindly help.
Ipython code -

This is a bug with integration between plotly 3.8.X and was reported on the cufflinks github issue tracker. A fix was merged, but I don't think that it is released yet.
Edit: 09/05/19 and 21/06/19 Updated my conda environment, but the bug remains.
I installed pytorch using pip3 command for my windows pc without GPU support.
But when I tried to import torch it is giving an error.
At first, there was a different error saying numpy version not matching and I updated the numpy to the latest version.
import torch
RuntimeError Traceback (most recent call last)

I reinstalled anaconda and then created a virtual environment for pytorch.Now everything works fine
If you are running this in colab, remember to restart your runtime after installing your modules with pip.
I try to do a basic igraph plotting in an IPython notebook:
fn = 'misrables.gml'
gr = igraph.Graph.Read_GML(fn)
igraph.plot(gr)
instead of seeing a graph I see this:
Out[7]: <igraph.drawing.Plot at 0x1120d6978>
How do I persuade IPython to actually show the graphics?
Some clarifications
Inline matplotlib works fine, so this is not the issue.
I have cairo installed:
import cairo
cairo.version
output: 1.10.0
Calling _repr_svg() on the plot object results in an error:
TypeError Traceback (most recent call last)
/Users/boris/Documents/workspace/communityAnalysis/src/utils.py in <module>()
----> 1 z = ig.plot(gr)._repr_svg_()
/usr/local/lib/python3.4/site-packages/igraph/drawing/__init__.py in _repr_svg_(self)
362 # No idea why this is needed but python crashes without
363 context.show_page()
--> 364 surface.finish()
365 # Return the raw SVG representation
366 return io.getvalue()
TypeError: string argument expected, got 'bytes'
Do you have the Cairo library and its Python bindings installed on your machine? The Plot object of igraph has a _repr_svg_ method that should be enough for IPython to show the plot, but _repr_svg_ uses Cairo behind the scenes to draw the graph into an SVG file, so if you don't have Cairo, _repr_svg_ probably throws an exception that IPython swallows, and then you get an ordinary repr() representation for the plot.
Update: based on the updated post, it turned out that the problem was that _repr_svg_ was not prepared for Python 3.x as it used a StringIO object where a BytesIO object would have been appropriate. Replacing io = StringIO() with io = BytesIO() at the beginning of the function and replacing return io.getvalue() with return io.getvalue().decode() at the end solves the problem. (from io import BytesIO is also needed at the top of igraph/drawing/__init__.py). A bug report has been filed on GitHub; the issue will be fixed in the next minor release.
Update: the issue is now fixed in the development version; see this commit for a patch.
Update for igraph 0.7.1 in python 3.7.4 and IPython 7.8.0
if you install the package with:
conda install python-igraph
Then you can simply use
igraph.plot(gr).show()
and in Ubuntu a .png will be displayed automatically in a separate window with ImageMagick
