I just started working through the fast AI course. While trying to load this cell on google collab:
from nbdev.showdoc import *``
I encounter the error: ModuleNotFoundError: No module named 'nbdev'. I've been trying to find an answer to this since a long time and couldnt find anything online. Any help in the matter will be greatly appreciated.
In the Colab environment you need to add:
!pip install nbdev
from nbdev.showdoc import *
it will work.

I am trying to add the BlossomV package in Julia. I am receiving the following error:
*LoadError: BlossomV not properly installed. Please run Pkg.Build("BlossomV")
LoadError: Failed to precompile BlossomV*
On running Pkg.Build("BlossomV"),
I am getting the following error:
*LoadError: IOError: could not spawn setenv(*A lot of attributes are there here*): no such file or directory (ENOENT)*
I am facing this error on both Windows 10 and Ubuntu.
I would appreciate it if anyone could explain what the issue is and how to solve it. Thank you.
BlossomV.jl is just a wrapper around a C library and I bet it is the process of building the C library that's failing. BlossomV is designed around the old approach to handling binary dependencies. It would be great to either rewrite it using pure Julia, or use the modern "artifact" system which is a vastly more robust way to ship binary dependencies.
I want to learn Qt especially for the 3D functionalities and therefore was following this tutorial.
One part of the tutorial is displaying the mesh from a .dae file called object.dae.
When I tried to run my code for the first time, I got the following error:
2:25:52: Starting /home/qt/build-Qt3DTests-Desktop_Qt_5_15_2_GCC_64bit-Debug/Qt3DTests ...
Qt3D.Renderer.SceneLoaders: Qt3DCore::QEntity* Qt3DRender::Render::LoadSceneJob::tryLoadScene(Qt3DRender::QSceneLoader::Status&, const QStringList&, const std::function<void(Qt3DRender::QSceneImporter*)>&) Found no suitable importer plugin for QUrl("file:../Qt3DTests/Models/object1.dae")
22:26:00: /home/qt/build-Qt3DTests-Desktop_Qt_5_15_2_GCC_64bit-Debug/Qt3DTests exited with code 0
I proceeded to clone the repo (tag: STEP_001) and try running it but again I receive the same error.
As this was the first Qt tutorial and C++ code I ever did, I am unsure what could be the problem. Does anybody know what is going wrong? Am I missing some module in my installation or something?
The cause might be this (rare) bug in Qt:

I am running a virtual environment with Python 2.7 for my program.
There seems to be a problem after creating the executable file on windows.
I ran venv/Scripts/pyinstaller.exe -F main.py
everything seems fine. But when i click on the created executable main.exe.
There is an error.
Tried and tested
I have re-installed of pandas and pyinstaller
Implemented the hook-pandas.py to the hooks folder in the environment.
hook-pandas
Ensured the environment is activated.
Checked that the program is running fine before building executable.
Re-created the environment.
Yet after all that, I am prompted with this issue [see Importerror] when I run the executable file.
It is an extreme pain to debug this because the command prompt displaying the error will not pause but close almost immediately.
Similar issues
Looking for Suggestions
I am hoping for suggestions to troubleshoot Pyinstaller. Any resources to read up on would be nice.
Usually, I have no trouble with python as Pycharm has several handy debugging tools that will help me identify the problem
I ran into the same problem and found this thread, but I managed to solve it borrowing from the reference you posted (about pandas._libs.tslibs.timedeltas), so thank you for that!
In that article, the module that resulted in the ImportError was, in fact pandas._libs.tslibs.timedeltas, if you look at the poster's logs. But the error you and I ran into refers to np_datetime instead. So, from the traceback logs, I finally figured out that the code we have to write in hook-pandas.py should be the following:
hiddenimports = ['pandas._libs.tslibs.np_datetime']
Maybe that alone will solve your problem, HOWEVER, in my case, once I solved the np_datetime issue, other very similar ImportError problems arose (also related to hiddenimports regarding pandas), so, in case you run into the same issues, just define hiddenimports as follows:
hiddenimports = ['pandas._libs.tslibs.np_datetime','pandas._libs.tslibs.nattype','pandas._libs.skiplist']
TL;DR:
You can first try to write
hiddenimports = ['pandas._libs.tslibs.np_datetime']
into hook-pandas.py. However, if for some reason you run into the exact same issues I did afterwards, try
hiddenimports = ['pandas._libs.tslibs.np_datetime','pandas._libs.tslibs.nattype','pandas._libs.skiplist']
If you wish to dive deeper (or run into a different pandas ImportError than the ones I did), this is the code in pandas's __init__.py referenced in your traceback log (lines 23 to 35):
from pandas.compat.numpy import *
try:
from pandas._libs import (hashtable as _hashtable,
lib as _lib,
tslib as _tslib)
except ImportError as e: # pragma: no cover
# hack but overkill to use re
module = str(e).replace('cannot import name ', '')
raise ImportError("C extension: {0} not built. If you want to import "
"pandas from the source directory, you may need to run "
"'python setup.py build_ext --inplace --force' to build "
"the C extensions first.".format(module))
From that I went into the
C:\Python27\Lib\site-packages\pandas_libs
and
C:\Python27\Lib\site-packages\pandas_libs\tslibs
folders and found the exact names of the modules that resulted the errors.
I hope that solves your problem as it did mine.
Cheers!
Not sure if any one of you have ever faced this issue. I have tried checking various sources online but nothing solved my issue.
I am following a tutorial on how to create a Meteor+ionic+react application from this link
https://medium.com/#SamCorcos/meteor-react-ionic-mobile-app-part-1-the-basic-template-9355ebf3397f#.qtl4fl5st
when i add the line
ReactRouter=require("react-router");
inside app.browserify.js and run the application, i get the following error.
Error: Cannot find module 'react/lib/invariant'
I am using following versions
react 0.14.3
cosmos:browserify 0.9.3
meteorhacks:npm 1.5.0
npm-container 1.2.0+
I am surely missing something thing here. Can anyone help.
Thanks,
Sri TejN
I found the solution myself. Just install the ReactRouter that is present in the meteor packages and do not include the line “ReactRouter = require(“react-router”);” in the file “ app.browserify.js”. But you can use the variable ReactRouter anywhere else in the code.
Just to confirm, in my case the solution also worked and added ReactRouter package:
meteor add reactrouter:react-router
Then commenting out line:
//ReactRouter = require("react-router");
In file lib/app.browserify.js and running Meteor again fixed the problem.
Thanks Sri Tej Narala.
I'm currently trying to start a play-slick application through the Typesafe Activator, but it fails to load the SBT configuration and I get this error;
/play-slick/build.sbt:30: error: reference to fork is ambiguous;
it is imported twice in the same scope by
import _root_.play.Project._
and import Keys._
fork in run := true
^
Type error in expression
Failed to load project.
Does this mean I have SBT downloaded twice and what can I do to resolve it? Thanks.
Just wanted to say that I came across this exact same issue when trying to use the Play-Slick example linked from the Play Tutorials page.
The solution to get it working seems to have indeed been to follow the suggestion in the Github link that Seth Tisue included in a comment above, where corruptmemory suggested removing the following line from build.sbt:
fork in run := true
In my case, this was enough to convince IntelliJ to open the project and let me tinker with it. (Just in case this is the first result for anyone else coming across this problem)
just remove
fork in run := true
from build.sbt and hit activator clean run from cmd
