Python 64 bit on windows: OSError: [WinError 193] %1 is geen geldige Win32-toepassing

For a long time I'm using a 32-bit python interpreter without a problem. Lately I installed a 64-bit interpreter and installed Anaconda which python has the following info:
Python 3.7.3 (default, Apr 24 2019, 15:29:51) [MSC v.1915 64 bit (AMD64)] :: Anaconda, Inc. on win32
When I try to run some code for example
'Import pandas as pd' then I get the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\sveno\Anaconda3\lib\site-packages\pandas\__init__.py", line 13, in <module>

self._handle = _dlopen(self._name, mode)
OSError: [WinError 193] %1 is geen geldige Win32-toepassing
Deleting the 32-bit version does not solve the problem

Nanomsg import error

I'm having problems using NanoMsg. I was using default sockets before but then someone pointed out that this was a bad idea. So I searched to get a better package and found NanoMsg. When I tried importing I got this error:

Any solutions?

Raspberry Pi Radio Transmitter Error

I have read that the Raspberry Pi is capable of transmitting FM.
I have downloaded the script and put on the directory "/home/pi/".
Then I have executed following commands in the terminal over putty:

I have ensured that the soundfile "left_right.wav" is in the same directory.
I don't know why this error is throwed.
I use Raspbian as OS, if this is revelant...

I'm trying to install pyquery on Windows and I get the following error when I try to do selects like this d('p:first'). Everything else seems to be working. Any idea what am I missing? This issue happens only on my windows machine, on my MAC works fine.

I had installed pyquery with "easy_install pyquery" and this was causing this error.
I removed it and then installed it from https://github.com/gawel/pyquery with python setup.py install and now it's working.
