I'm trying to install djinn-lib with GHC 8.4.1 (from Ubuntu 16.04 apt-get).
$ cabal install djinn-lib
But I get an error about ambiguity in the <> operator as shown at the bottom.
Does anyone know how to go about fixing it?
The cabal version I used was:
$ cabal --version
cabal-install version 2.2.0.0
compiled using version 2.2.0.0 of the Cabal library
The error message is:
$ cabal install djinn-lib

TLDR:
await d.preview() # throws "NameError: name 'launch' is not defined"
# d.preview() # does not throw "NameError: name 'launch' is not defined"; however, it still does not produce the desired image in a jupyter notebook... It's __repr__ prints <coroutine object DashBoard.preview at 0x7f44013aaa70>`
I'm trying to preview a rapids dashboard that is correctly rendering in a separate browser window. However, when I try to preview a rasterized screengrab of the dashboard using the convenient looking plotly method, d.preview(), I keep getting this paradoxical exception, "NameError: name 'launch' is not defined".
await d.preview() works in the documentation here:
https://docs.rapids.ai/api/cuxfilter/stable/themes/Themes.html
I am running rapids21.08 in python3.7 on ubuntu (Pop!_OS 20.10) using an RTX2080 GPU using a jupyter notebook with the default jupyter theme made using $ jt -r, and I am not using any matplotlib funny business. I have run the very common import matplotlib.pyplot as plt command.
This seems like a really common problem which I'm surprised isn't just working... Maybe there's something obvious I'm just missing... Please help me!
The full exception can be found postscript.
Thank you for your time,
Tim
P.S.

This is probably due to the missing pyppeteer package. Installing this in the conda env should resolve the issue:
conda install -c conda-forge pyppeteer>=0.2.6
cuxfilter=21.10 won't have this issue, as the dependency has been added to it.
(Arch linux) I have been having a lot of problems lately with haskell packages. Normally I would fix them fairly easily by updating some packages, but there is probably a root cause to all of them that I cannot figure out. I currently think the most likely explanation is that I went wrong somewhere in the haskell installation process, as I did not use the “haskell platform” but somewhat haphazardly installed packages from all over the place when I needed them. I just performed a system upgrade, and now when I run startx, this is the result. The shared object file it references near the end, libHSxmonad-contrib-0.16-AAxGT3H9yrS67i4YFgpjoh-ghc8.10.1.so, does not in fact exist, but two libHSxmonad-contrib shared object files that end in ghc8.0.2 (which is my ghc —-version) do exist. Also, most of the packages it says are missing I remember installing (some via cabal, some pacman) at some point or another. If it helps, here is my cabal list —-installed, ghc-pkg check, and pacman -Q|grep haskell.
[Arch Linux] I am not sure if this is related, but recently I've been increasingly annoyed by the recurrent frequency of interminable Haskell package updates -- in my case virtually solely triggered by my pandoc installation.
Resolution
yay -Syu ## system update; alt: sudo -Syu
sudo pacman -R pandoc ## uninstall pandoc
## ----------------------------------------
## Repeated cycles (~5-6) of the following, until nothing shown:
sudo pacman -Qdt ## list all packages no longer required
## as dependencies (orphans) ...
sudo pacman -R $(pacman -Qdtq) ## ... and delete them
## ----------------------------------------
yay -Syu ## system update; alt: sudo -Syu
Update. For clarity, run as many cycles as needed of:
sudo pacman -R $(pacman -Qdtq)
To find dependencies , use pactree :
[victoria#victoria ~]$ pactree -h
pactree v1.8.2
Package dependency tree viewer.

Recently a package on CRAN that I am maintaining gets the following error:
(I did not change anything - error just was not present before - CRAN probably added additional checks)
Result: WARN
Output from running autoreconf:
autoheader: warning: missing template: HAVE_GSL_HEADER
autoheader: Use AC_DEFINE([HAVE_GSL_HEADER], [], [Description])
autoreconf: /usr/bin/autoheader failed with exit status: 1
Flavors: r-devel-linux-x86_64-fedora-clang, r-devel-linux-x86_64-fedora-gcc
Here is the link to the CRAN check page:
https://cran.r-project.org/web/checks/check_results_ridge.html
The error seems to appear only for r-devel-linux-x86_64-fedora-clang, r-devel-linux-x86_64-fedora-gcc.
Github Link to package Source Code:
https://github.com/SteffenMoritz/ridge
The package uses the GSL lib. (if somebody wonders about the GSL in the error message)
Unfortunately I only overtook maintenance of the package and don't have too much idea about the C things.
I assume, the error message has nothing to do with the R part of the package. Do I have to add the AC_DEFINE somewhere in the C files?
Could somebody explain me, what exactly the error message says to me. Guess this might already help me to figure things out.
edit:
Think I have to change something in this file (just a guess)
https://github.com/SteffenMoritz/ridge/blob/master/configure.ac
But the code there is the following:
if test "${HAVE_GSL}" = TRUE; then
dnl Define HAVE_GSL_H in src/config.h
AC_CHECK_HEADERS([gsl/gsl_version.h],AC_DEFINE(HAVE_GSL_HEADER), [HAVE_GSL=FALSE])
if test "${HAVE_GSL}" = FALSE; then
AC_MSG_WARN([gsl headers not found, perhaps check the path?])
AC_MSG_WARN([ridge will be installed, but some functions will be
unavailable])
fi
fi
So it seems there is a statement AC_DEFINE(HAVE_GSL_HEADER), [HAVE_GSL=FALSE]).
Put the below into a file called diff.patch or whatever you like in the top directory.
diff --git a/configure.ac b/configure.ac
index e643140..0b256a6 100644
--- a/configure.ac
+++ b/configure.ac
## -22,7 +22,8 ## fi
if test "${HAVE_GSL}" = TRUE; then
dnl Define HAVE_GSL_H in src/config.h
- AC_CHECK_HEADERS([gsl/gsl_version.h],AC_DEFINE(HAVE_GSL_HEADER),[HAVE_GSL=FALSE])
+ AC_CHECK_HEADERS([gsl/gsl_version.h],
+ AC_DEFINE(HAVE_GSL_HEADER, [], [Description]),[HAVE_GSL=FALSE])
if test "${HAVE_GSL}" = FALSE; then
AC_MSG_WARN([gsl headers not found, perhaps check the path?])
AC_MSG_WARN([ridge will be installed, but some functions will be unavailable])
Run patch -p1 < diff.patch.
Now autoreconf should rebuild all just fine.
By trying to compile QGIS from sources on Ubuntu, there is the file /opt/QGIS/cmake/FindSIP.py which content is:
import sipconfig
sipcfg = sipconfig.Configuration()
print("sip_version:%06.0x" % sipcfg.sip_version)
print("sip_version_num:%d" % sipcfg.sip_version)
print("sip_version_str:%s" % sipcfg.sip_version_str)
print("sip_bin:%s" % sipcfg.sip_bin)
print("default_sip_dir:%s" % sipcfg.default_sip_dir)
print("sip_inc_dir:%s" % sipcfg.sip_inc_dir)
# SIP 4.19.10+ has new sipcfg.sip_module_dir
if hasattr(sipcfg, "sip_module_dir"):
print("sip_module_dir:%s" % sipcfg.sip_module_dir)
else:
print("sip_module_dir:%s" % sipcfg.sip_mod_dir)
In Python3.6, the last if/else statement prints:
sip_module_dir:/usr/lib/python3.6/dist-packages
But the string /usr/lib/python3.6/dist-packages doesn't match an existing directory (it is probably part of why I encountered the error:
python/CMakeFiles/python_module_qgis__core.dir/build.make:537: recipe for target 'python/core/sip_corepart0.cpp' failed' failed during build process).
I either have:
/usr/lib/python3/dist-packages
or
/usr/lib/python3.6/site-packages
And it's only in /usr/lib/python3/dist-packages that I have some 'sip' related files (the other directory gives no results):
$ find . -iname "*sip*"
./twisted/protocols/__pycache__/sip.cpython-36.pyc
./twisted/protocols/sip.py
./twisted/test/test_sip.py

./__pycache__/sipdistutils.cpython-36.pyc
./__pycache__/sipconfig.cpython-36.pyc
./sip.cpython-36m-x86_64-linux-gnu.so
I guess there is something to fix within 'sip' itself but don't know where exactly, neither how to do that.

I'm trying to use the rmagic extension for the IPython notebook, using Python 2.7.6 via Enthought Canopy.
When I try the following example:
import numpy as np
import pylab
X = np.array([0,1,2,3,4])
Y = np.array([3,5,4,6,7])
pylab.scatter(X, Y)
%Rpush X Y
%R lm(Y~X)$coef
I get an error:
AttributeError Traceback (most recent call last)

215 except (ri.RRuntimeError, ValueError) as exception:

AttributeError: 'module' object has no attribute 'ri2py'
I can't find anyone else who's had the same problem and don't know enough to solve it myself. There is no definition for ri2py in conversion.py though.
I initially had installed Anaconda and was running python notebook through that, with exactly the same results.
rpy2 (version 2.4.0) installed successfully but when I test it I get 1 expected failure as follows:
python -m 'rpy2.robjects.tests.__init__'
…
testNewWithTranslation (testFunction.SignatureTranslatedFunctionTestCase) ... expected failure
I don't know if that's related.
Can anyone suggest what the problem might be and how I might fix it? Are the versions of python, R, etc. that I'm using compatible or do I need to re-install/update something?
Are you using %load_ext rmagic?
If so, try using %load_ext rpy2.ipython instead.
This is one of the new features in version 2.4.0.
