First, thank you Joachim for pyILPer.

I can't get it to run and I am not familiar enough with Python to deal with the error.
I downloaded and installed Anaconda.
I updated and I have Python 3.6.1
I installed LIFUtils

When I installed Anaconda, it gave me an option to either modify the PATH (Not recommended) or register it (I chose this option).

I added the channels for bug400
I installed pyILPer
I updated all

Here is a version listing and the error I get when I try to run pyILPer. It seems to fail at when loading QT5?

Any thoughts?

Did you install Miniconda first?

I see that you have an Anaconda3 folder in ProgramData. I do not, so maybe that's a clue.

That is a clue, maybe. I thought that Miniconda is supposed to be just a minimal Anaconda installation to save space, so I just installed the full Anaconda. But, it's certainly something to try. Thanks Dave.

(P.S. Thanks, too for your "HP" parts on Shapeways)

Please try to run pyilper from the ANACONDA command prompt. You should find this entry in the
Windows start menu. This should set the proper environment to call ANACONDA applications.

Thank you Joachim. That's what I did. From the Anaconda command window, I get the following error. It seems to crash when trying to set up the QtGUI and Qtwidgets.

So, I've had a go at uninstalling and re-installing Anaconda both for "all" users and just for me, I also did it unchecking and checking the box to allow the installer to modify the system PATH and verified that the library path where the PyQt5 dll's are located is in the PATH.

I verified that PyQt5 is in fact installed (it's in the list) but it still crashes in the pyilpermain.py file at line 136 which is:
"from PyQt5 import QtCore, QtGui, QtWidgets"

I highly doubt it is the fault of pyILPer, but something in my installation/configuration. I've searched the Anaconda boards but have not found anything that has helped. Anyone have any ideas?

Hi Dave,

Yes, great suggestion. ILPer is installed and working great.

I am more and more convinced that Anaconda/Miniconda have a configuration issue with my particular system, although I have nothing special or odd installed/running.

I will pursue this on the Anaconda forums and I have just installed a plain Python package and will try to run pyILPer in that environment. I am simply very intrigued by the HP plotter emulation. Way back when, I had interfaced my HP41 with a Radio Shack 4 pen mini plotter that used a 4 inch wide paper roll. I loved it. I want to explore the plotter stuff now with my 71 and 41.

I appreciate your ideas.

David

You can check if it is an Anaconda-only problem with:

- Open an Anaconda prompt
- Type "python". This starts the python interpreter. It should say:
Python 3.6.1 ... Anaconda custom ... (xx-bit) ...
- type:
from PyQt5 import QtCore, QtGui, QtWidgets

If this throws an error it is an issue of the Anaconda installation.
Exit the interpreter with Ctrl-Z

It is most likely a problem of missing or incompatible DLLs. Unfortunately not an Windows expert
to give an advice how to check dependencies.

I did a clean install of Anaconda (Python 3.6, 64bit) and pyILPEER on a Windows 10 64 bit system
with no issues.

Did you install a 32 bit version of Anaconda on a 64 bit Windows? This could cause trouble.

Regards
Joachim

Thank you Joachim. I get the same error, procedure could not be found. It is a 64 bit Anaconda on Windows 10 Professional 64 bit.

I noticed in your instructions, when you type "python" your installation information says "... Anaconda custom ..." I did not do a custom installation. What is custom about your installation?

Thank you for your help

Hi,

your list of installed software (post #1) is the same as mine. The startup message of my python interpreter is:

Code:

Python 3.6.1 |Anaconda custom (64-bit)| (default, May 11 2017, 13:25:24) [MSC v.1900 64 bit (AMD64)] on win32

Type "help", "copyright", "credits" or "license" for more information.

>>>

My only variation of the standard installation is that I changed the installation path.

On stackoverflow there are recommendations to use the depends.exe utility (please google the link) to check for unresolved dll entries.

You should start the utility in the Anaconda prompt and examine the file: (Anaconda path)\lib\site-packages\PyQt5\QtCore.pyd. Note: the message "... missing ... function ... in delay-load dependent module" indicates that this reference to a dll function is resolved at runtime. Most likely the application provides fall backs if the required function could not be found.
This can not be checked by depends.exe.

Regards
Joachim

Thank you for all your time and help Joachim. I have some positive progress to report. I did a basic Python 3.6 install without the Anaconda wrapper and I think it was able to install pyILPer and when typing in the line "from PyQt5 ..." that was giving me the error as you suggested I try in Anaconda, it seems to execute in the bare Python environment just fine. This leads me even further to the conclusion this is really an Anaconda configuration/installation error.

I'll give that depends.exe a try, too, but I may just stick with what seems to be on a path that will work. I think I managed to "install" pyILPer, but I have not studied Python enough to actually know how to use the environment and use pyILPer, but when I get a little time to study Python, I think I'll be able to run everything there. Anaconda sure makes Python easier, I think, but I'll be happy to just run your excellent application!

David
