AttributeError: 'PhotoImage' object has no attribute '_PhotoImage__photo'
So I was doing a project in pycharm. how do I Solve this problem?

line 35, init self.bg = ImageTk.PhotoImage(file="unnamed.png")
Where is the file unnanmed.png located?
Use :
self.bg= ImageTk.PhotoImage(Image.open(file_path))
file_path should be full or relative path of the file if it is not in the root directory.

Python-Bitcoinlib - FileNotFoundError: Could not find module 'libeay32'

I suspect this is a bit of a newb question, but I'm trying to run the following code using IDLE Shell 3.9.1:
from bitcoin.rpc import RawProxy
p = RawProxy()
info = p.getblockchaininfo()
print(info['blocks'])
And I am getting the following error:

FileNotFoundError: Could not find module 'libeay32' (or one of its dependencies). Try using the full path with constructor syntax.
Any thoughts on how to get beyond this? Thanks for your help!

Can not import theano after installation windows 10

I've still not been able to resolve this problem, after working on it for a week.
I'm thinking of giving up and just running theano on a virutal machine; there just doesn't seem to be any support out there for Windows 10!
Or am I wrong; is there an easy fix to this?

Um, can't concat bytes to str? What does this mean?

The error you are experiencing appears to result from another sub-process utilizing the same resources as the script you are attempting to write. Although it sounds trivial, I would recommend making sure that you have admin privileges, or at least privileges to the desired resources, and/or restart your computer to kill the sub-process using that module. You could also look in the task manager and kill any/all other processes using python, but that might take longer.
(This may be the program using the "resource" try_march_3v6ffkv9.exe)

Python: Broken Pipe Error For PyNomo Example (in function Nomographer)

I am using pycharm on Python 2.7. I have installed PyNomo. I am trying to run this small example from the official site. Code is available on the link, I have simply copy pasted it. I get the following error:

The error is in the final line of the code:

I have looked at other questions with "broken pipe error": here,here, and here. But none of them are helpful to me.
Any indication on how to solve would be very helpful.

PyNomo uses a TeX installation to typeset text. Maybe this is missing resulting in a broken pipe. You need to be able to run a file hello.tex with the content Hello, world!\bye on a command line tex hello.tex. It should result in a file hello.dvi. If not you need to install a TeX distribution like TeXLive.
