Missing module 'ephem' #1

Closed kzembower closed 4 years ago

kzembower commented 4 years ago

After successfully following directions to install on Linux, got this error:

$ python3 skyalmanac.py

Even after installing module 'ephem' still get same error:

Let me know if you need me to test anything.

I have no Linux installation to test on, however here is an idea I found on the web:

sudo apt-get update
sudo apt-get install python-ephem

Link: How to install python-ephem on Ubuntu 16.04

or to install on Python3:

sudo apt-get update -y
sudo apt-get install -y python3-ephem

Link: How To Install "python3-ephem" Package on Ubuntu

Also may be useful: How to Install python3-ephem software package in Ubuntu 17.04

Cannot install pyephem for python3

Let me know if this helps as I need to update the Linux installation instructions. Andrew P.S. I already responded by email with other suggestions.

Hi, Andrew, thanks for the suggestion.

That seemed to work, but the error remains the same:

I appreciate your willingness to help. I really enjoyed using the old PyAlmanac.

You are using Python3, so please try:

sudo apt-get update -y
sudo apt-get install -y python3-ephem

I'm sure we can get this to work. What Linux software are you using? The original code was Python 2. The original Pyalmanac web site now contains a Pyalmanac version for Python 3, but there is a link to Pyalmanac in a Python 2 version on my GitHub site.

I think my email never reached you... could you also attempt to run this code (a simple test):

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import ephem

m = ephem.Mars('2003/8/27')
msg = "%s %s %.10f" %(m.name, m.elong, m.size)
txt = "Mars -173:00:34.2 25.1121063232"
print(msg)

if msg != txt:
    print("   --- INCORRECT ---")
else:
    print("   ==> correct answer <==")

Also, as this is a PyEphem installation issue, I wrote an email to the author, Brandon Rhodes, at: brandon@rhodesmill.org

Kind Regards, Andrew

Hi, Andrew,

Well, installing python3-ephem seemed to fix one problem, but revealed another:

$ sudo apt-get install python3-ephem ... The following NEW packages will be installed: python3-ephem ... Unpacking python3-ephem (3.7.6.0-7build1) ... Setting up python3-ephem (3.7.6.0-7build1) ... $ python3 skyalmanac.py Traceback (most recent call last): File "skyalmanac.py", line 20, in import tables File "/home/kevin/SkyAlmanac/SkyAlmanac-Py3-master/tables.py", line 24, in from alma_skyfield import * File "/home/kevin/SkyAlmanac/SkyAlmanac-Py3-master/alma_skyfield.py", line 24, in from skyfield.api import Topos, Star, load ModuleNotFoundError: No module named 'skyfield' $ sudo apt-get install skyfield ... E: Unable to locate package skyfield $ sudo apt-get install python3-skyfield ... E: Unable to locate package python3-skyfield $ sudo apt-get install python-skyfield ... E: Unable to locate package python-skyfield $

As you can see, I tried a couple of logical options, without success.

Not sure what you're asking re: What Linux software I'm using. I only run Linux, and use a great variety of Linux software.

I've only received three emails from you, none of them long. Two were in regard to this issue, and the first one was in regard to the patch I developed for the previous author of PyAlmanac regarding date printing. It's subject was "Re: [rodegerdts/Pyalmanac] Fix for lack of printing date in meridian passage tables (#1)"

Let me know how I can help. Thanks for working on this issue.

@kzembower — My guess is that your system has both Python 2 and Python 3 installed, and that you are installing packages under Python 2 with the pip command. This leaves the separate Python 3 install without any of the packages you are looking for.

If you install the Ubuntu package python3-pip, you will get a pip3 binary that installs packages for Python 3. Running pip3 install ephem skyfield should hopefully get you up and running.

I always use "virtual environments" instead of trying to install things system-wide. Other folks who are more involved in the science community used the Anaconda ecosystem. One of the more modern guides to installing packages (though maybe not the best? I've not read many of the new ones) is:

https://packaging.python.org/tutorials/installing-packages/

Hopefully the above hints will get things working for you!

aendie commented 4 years ago

One more tip - if you enjoyed using the old Pyalmanac, you can of course stay with Pyalmanac. This does not require the new Skyfield package. Download (don't fork) either the Python 2 or Python 3 version depending whether you want to remain with Python 2 or "upgrade" to and run it with Python 3.

Pyalmanac for Python 2 is here: https://github.com/aendie/Pyalmanac-Py2 Pyalmanac for Python 3 is here: https://github.com/aendie/Pyalmanac-Py3

Good luck and let us know if this works. Pyalmanac runs fastest!

P.S. "Re: [rodegerdts/Pyalmanac] Fix for lack of printing date in meridian passage tables (#1)" is a PULL request to Enno's GitHub site from 7 Nov 2017 and is obsolete. That's why I closed it. It is no longer relevant (and incompatible with the latest version).

kzembower commented 4 years ago

Brandon and Andrew, thanks so much for devoting so much time and energy to helping me.

Brandon, you are absolutely right that I run both Python2 and 3. You would also be correct in assuming that I don't know much about administering them.

I believe that your suggestion fixed my problem. At the end of this note, I've pasted in the extensive output of installing the modules and running the skyalmanac program. The only change in your directions that I had to make was to run 'pip3 install ephem skyfield pandas'. The program seemed to run normally after this. However, now it looks like I'm missing pdflatex; I'll investigate this. Also, it looks like nothing was generated when this error occurs; I can't find anything in the current directory with today's date.

Brandon or Andrew, by the way, did either of you accept my pull-request to fix the code to print the date in meridian passage tables, in the original PyAlmanac?

Also, I noticed that there are PDF document included for A4 paper. Any chance to amend these for North American 'letter' size paper?

Thanks, again, for all your help. Let me know if there's anything I can do.

Hi, Andrew, thanks for the tip. I was interested in the SkyAlmanac because I thought it had increase accuracy over PyAlmanac. Time to generate doesn't much matter to me; I run it once then use the pages throughout the year.

Thanks, again, for all your work on this project.

Brandon and Andrew,

I was successful in installing pdflatex, from the package texlive-latex-base. However, there were still some problems. I pasted in the end of the run of 'python3 skyalmanac.py' at the end of this note. No output files were written in this run.

Here are three seemingly significant errors:

! LaTeX Error: File `multirow.sty' not found.

! LaTeX Error: File `tikz.sty' not found.

pdfTeX warning: pdflatex (file ./A4chart0-180_P.pdf): PDF inclusion: found PDF version <1.5>, but at most version <1.4> allowed

pdfTeX warning: pdflatex (file ./A4chart180-360_P.pdf): PDF inclusion: found PD F version <1.5>, but at most version <1.4> allowed

On a completely unrelated note, what's the difference between Traditional and Modern formats?

Thanks, again.

Hopefully the above hints will get things working for you!

Okay. That's good progress you are making. Again I am handicapped not having a Linux (Ubuntu or Debian) installation, but I try to make useful suggestions. Just for information: when using MiKTeX on Windows 10, this includes pdflatex and installs any missing components (such as multirow, tikz, booktabs, colortbl, xcolor, etc.) on-the-fly.

So I simply Googled your error message and came up with this suggestion to install the missing 'multirow' package (I don't know what the following commands mean):

tlmgr update --self
tlmgr install multirow

... and this link was referenced: https://yihui.org/tinytex/

However, since I like the way that MiKTeX is regularly maintained and installs any missing required packages automatically, perhaps you would consider de-installing your current pdlaftex software and installing MiKTeX on Linux? Instructions are here: https://miktex.org/howto/install-miktex-unx

The difference between 't' (traditional) and 'm' (modern) style layout is that 't' looks like the original Pyalmanac tables and also like a printed Nautical Almanac. I designed 'm' to use the booktabs package for some tables as well as a bit of color. This table style is recommended for LaTeX authors.

Here I include two sample mini-almanacs: sample_almanacs.zip Note that a small sample (beginning with the current date) can be created using option 3 or 4.

You are right that the output is only for A4 sized paper - just like the original Pyalmanac. However your suggestion is good and I could look into it. It is sometimes a major battle to squeeze a lot of information onto one page using LaTeX without getting tons of Overflow or Underflow messages from pdflatex. So although it sounds simple, it is an art to achieve the desired result and takes a lot of "tweaking". That letter-sized paper is wider is an advantage - the problem arises that the height is less, but I may manage this by reducing the top and bottom margins. I will look into this as it would be nice to include LETTER size as an option. I'll consider this for a future update.

As always - stay in touch keeping us posted on your progress. Thanks!! Andrew

P.S. MiKTeX would solve the "PDF version <1.5>, but at most version <1.4> allowed" error as MiKTeX can handle it. I don't yet if I can create the older version 1.4 ... I'll look into it.

aendie commented 4 years ago

In this (SkyAlmanac-Py3) repository I recreated and replaced four PDF star charts with PDF v1.4 (previously they were PDF v1.5).

So you should not get the "PDF version <1.5>, but at most version <1.4> allowed" error any more.

Hope this helps - - - Andrew

kzembower commented 4 years ago

Andrew and Brandon, I've achieved significant success. I installed the Ubuntu package 'textlive-full'. It is a monster, with more than 2GB downloaded, and more than 4GB disk space used when unpacked. However, it seems to have all the packages needed for SkyAlmanac.

I didn't download the updated skymap files, but as the pdflatex message was a warning, not an error, it still compiled fine.

Man, are these pages beautiful! Thank you both for all the work you put into this. Your care and craftsmanship really shows.

Let me know if there's anything I can do to help.

Well done! And thanks for your continued efforts. I would like to have better guidelines for installing Skyalmanac on Linux, so I would appreciate your feedback on this.

I have now updated all the PDF files I posted on GitHub to PDF v1.4. They just don't need to be PDF v1.5 which was the default when I built them (using Hipparcos star data from Skyfield).

Your suggestion to implement Letter-formatted output has got me busy. I'm working on it. (There will be a parameter in the config.py file where you choose A4 or Letter.) It involves tweaking margin widths and even removing vertical spacing within tables in critical situations. It will be in the next update I release (initially for Skyalmanac).

aendie commented 4 years ago

All versions of Pyalmanac, SFalmanac and Skyalmanac can now create Letter-sized and A4-sized pages. A parameter in config.py selects the desired paper size.

The publisher on https://thenauticalalmanac.com/ has reported no issues and uses Ubuntu. I will close this issue if I don't hear from you in the near future. Thanks for your cooperation and tips.

aendie commented 4 years ago

I finally got Ubuntu 19.10 installed and I had similar issues as you had. For example, 

! LaTeX Error: File `multirow.sty' not found.
--------------------
! LaTeX Error: File `tikz.sty' not found.
--------------------

but the solution is this: sudo apt install texlive-latex-extra instead of installing texlive-latex-base.

I updated the instructions in GitHub - now for installing on Ubuntu 19.10 or higher (and a tiny change in skyalmanac.py in case no .log or .aux file is created). Thus I finally close this issue and hope you have no more troubles.

P.S. This web site has good information on the various TeX Live packages: https://tex.stackexchange.com/questions/245982/differences-between-texlive-packages-in-linux

kzembower commented 4 years ago

Absolutely, Andy. Please consider this issue closed. Thanks so much for all your work on this project.

I have a just-barely-related question for you, if you have the time. I'm hoping you can answer this based on your work creating the star-chart at the beginning of the Nautical Almanac, and your expertise with Python.

I would like to draw charts and forms like the Universal Plotting Sheet (which I'm sure you're familiar with) or Smith Charts (see https://en.wikipedia.org/wiki/Smith_chart). I know that, with enough work, any computer programming language can do any task, but would you recommend using Python to draw charts of this type? What Python modules would you use? Or, is there another system that you'd use to programmatically draw charts like these?

Thanks for your advice, and again, for all the work you do on the Nautical Almanac and Skyalmanac project.

Great question ... seeing as I studied Electronic Engineering at university (and forgot everything 6 months later). There are many Smith Charts available for download, so I'm guessing that your requirement is to generate your own Smith Chart and draw graphs according to scale on it.

Let's take this offline - reply with your email (add extra spaces and replace the '@' symbol with something). I'd be happy to work with you on this.
