Description of problem: I'm testing python-sympy and trying examples from a book on sympy I've found that 'preview' function from sympy module doesn't work. There are two reasons for this: 1. preview() requires python-pyglet module that is not marked as a dependency of python-sympy (no Requires neither Recommends). 2. python-pyglet is packaged without png submodule (this submodule deliberately removed in spec file without any reason except it duplicates another module's functionality). This causes the following exception in sympy (the output generated by VSCode jupyter plugin): --------------------------------------------------------------------------- ModuleNotFoundError Traceback (most recent call last) <ipython-input-17-3afb3d1abac0> in <module> 1 x,y = symbols('x, y') 2 a = x**3+2*x**2+5*x ----> 3 preview(a) /usr/lib/python3.8/site-packages/sympy/printing/preview.py in preview(expr, output, viewer, euler, packages, filename, outputbuffer, preamble, dvioptions, outputTexFile, **latex_settings) 279 280 if output == "png": --> 281 from pyglet.image.codecs.png import PNGImageDecoder 282 img = image.load(join(workdir, src), decoder=PNGImageDecoder()) 283 else: ModuleNotFoundError: No module named 'pyglet.image.codecs.png' Version-Release number of selected component (if applicable): python-sympy-1.4-5.mga8 How reproducible: always Steps to Reproduce: 1. Install python3-sympy package 2. Try to run the following python code: from sympy import * init_printing(use_unicode=True) x,y = symbols('x, y') a = x**3+2*x**2+5*x preview(a) Expected result: small GTK-based window with formula. Current result is an exception: Traceback (most recent call last): File "./test", line 7, in <module> preview(a) File "/usr/lib/python3.8/site-packages/sympy/printing/preview.py", line 281, in preview from pyglet.image.codecs.png import PNGImageDecoder ModuleNotFoundError: No module named 'pyglet.image.codecs.png'
Please test with python3-sympy-1.4-5.1.mga8 in Core/Updates_testing repo!

It should be 'join(workdir, src)' instead of 'fname' (tested and works). And what do you think about packaging and backporting the latest sympy 1.8? ;)
1.7.1 seems to work, thank you ))

Not a python user, so I am relying on the reporter's Comment 4 for functionality, and checking for a clean install. Installed the python(3)-sympy packages and their many dependencies in a 64-bit MGA8 VirtualBox guest. No installation issues. Attempted to install the python-sphinx-math-dollar packages, but they weren't in the repos, so I assumed they were new dependencies of the updated packages. Used qarepo to download all of the packages listed in Comment 5, then proceeded to the update: The following 6 packages are going to be installed: - lib64gst-gir1.0-1.18.3-1.mga8.x86_64 - python-sympy-doc-1.7.1-1.mga8.noarch - python-sympy-examples-1.7.1-1.mga8.noarch - python-sympy-texmacs-1.7.1-1.mga8.noarch - python3-pyglet-1.5.11-1.mga8.noarch - python3-sympy-1.7.1-1.mga8.noarch Note that python3-pyglet was pulled in as a dependency, as expected after reading Comment 0, but that the python-sphinx-math-dollar packages were not, leading me to now believe they aren't dependencies after all. Confusing, but not unheard of. There were no installation issues with the above packages. With the local qarepo still active, I asked to install the python3-sphinx-math-dollar packages: The following 17 packages are going to be installed: - python-sphinx-locales-3.4.1-2.mga8.noarch - python-sphinx-math-dollar-doc-1.2-1.mga8.noarch - python3-docutils-0.16-1.mga8.noarch - python3-imagesize-1.2.0-2.mga8.noarch - python3-packaging-20.4-1.mga8.noarch - python3-pygments-2.7.4-1.1.mga8.noarch - python3-snowballstemmer-1.9.1-2.mga8.noarch - python3-sphinx-3.4.1-2.mga8.noarch - python3-sphinx-math-dollar-1.2-1.mga8.noarch - python3-sphinx-theme-alabaster-0.7.12-3.mga8.noarch - python3-sphinxcontrib-applehelp-1.0.2-1.mga8.noarch - python3-sphinxcontrib-devhelp-1.0.2-1.mga8.noarch - python3-sphinxcontrib-htmlhelp-1.0.3-1.mga8.noarch - python3-sphinxcontrib-jsmath-1.0.1-3.mga8.noarch - python3-sphinxcontrib-qthelp-1.0.3-1.mga8.noarch - python3-sphinxcontrib-serializinghtml-1.1.4-1.mga8.noarch - python3-sphinx_rtd_theme-0.4.3-4.mga8.noarch As you can see, that drew in a lot more dependencies. But, all installed without issue, so it appears that this is good to go. Validating. Advisory in Comment 5. A number of assumptions in that, so if I am in error, please let me know.
