I understand how to run a single notebook in Colab. However, I am not sure how to use all files from a repository, i.e to be able to import functions inside Colab notebook?
Thank you.
Let's say we want to run the ipynb file, named as "1-fully-connected-binarized-mnist" residing in the repo "qnn-inference-examples".
https://github.com/maltanar/qnn-inference-examples
The notebook of interest uses customly created QNN library and functions inside that repo. Yes we need to import that function. To do this, we should first upload the repo folder to Google Colab, then correct/modify library and file paths.
0) Open the ipynb file "1-fully-connected-binarized-mnist" on your Colab. You can rename it if you like.
Try to run it, but will probably get some errors (as I did). So let's fix these issues
1) Insert a new code cell at the top of the notebook. And clone the repo on your Colab:
!git clone https://github.com/maltanar/qnn-inference-examples.git
now the new folder "qnn-inference-examples" created under your "content" folder. you should see something like this on the left side. And remember the path "/content/qnn-inference-examples"
2) Now add the second new cell on top:
import sys
sys.path.insert(0,'/content/qnn-inference-examples')
This will fix the issue about not able to find the library location, when trying import the QNN libraries.
3) Manually fix the file links on the existing code, according to the new path. Because the library and files now exist under the folder "/content/qnn-inference-examples":
for example replace:
img = Image.open("7.png")
with
img = Image.open("/content/qnn-inference-examples/7.png")
These steps should do the work

Please see the example below:
!git clone https://www.github.com/matterport/Mask_RCNN.git
from google.colab import files
files.os.chdir('Mask_RCNN')
# To find local version of the library
sys.path.append(os.path.join(ROOT_DIR, 'Mask_RCNN'))
# here is your import
from mrcnn.config import Config

Here is an example project folder structure similar to my actual project.
-repo_folder
--app_folder
---GUI_folder
----GUI1.py
----GUI2.py
---calculations_folder
----calculations1.py
----calculations2.py
---main.py
--cli.py
cli.py points to main.py. Main.py only import GUI1.py. And from there GUI2.py is imported and so on.
Basically, is there an easy way to make sure that all the importing done in each file is included? I have not been able to succesfully export a project with this kind of folder setup succesfully using pyinstaller. I keep getting "Failed to execute script cli" or "No module named GUI".
Could someone make an example of how the code would be import for a project structured like the above?
I'm very new to Golang. I see that in Golang you can import packages directly from Github like:
import "github.com/MakeNowJust/heredoc"
Does that mean I have to remember this URL in order to use this package? IMHO this is not cool. What if later the author of the package removed it or changed the URL? Any ideas?
I would recommend you to read the How to Write Go Code documentation and this blog post.
The path you're seeing in your import line is not a url, but only the path the package is located in (normally relative to $GOROOT/src/pkg or $GOPATH/src). So your package heredoc is most probably located in the directory $GOPATH/src/github.com/MakeNowJust/heredoc.
The recommended way to use external packages is by downloading and installing them via go get. You might want to check out the documentation of go get by go get --help.
The path that import statement refers is just appended to $GOPATH/src. So that import statement basically says "import the package located at $GOPATH/src/github.com/MakeNowJust/heredoc"
What if later the author of the package removed it or changed the URL?
As long as you already have the source files for that package at the expected location, it should be included even if the repo has moved.
dont worry man! you can use glide tool for package management
I'm trying to use import a package for internal use, but I have been having some issues.
My directory structure looks like this:
app/
model/
file1.go
file2.go
...
main.go
When I try to build the program, I get an error that looks something like this:
/usr/local/go/src/pkg/model (from $GOROOT)
I want to be able to call the model programs in any of my other programs in the app simply using:
import "app/model"
What are my options when it comes to doing this?
You import from GOPATH level .. all of your packages should live there.
For example, assuming your application is here:
$GOPATH/src/dtrinh100/app/
..and your package you wish to import is here:
$GOPATH/src/github.com/other/package
Your import would be:
import "github.com/other/package"
You should review the literature around what the GOPATH environment variable is all about. When beginning Go, it is important you understand its purpose and initially, you should place all of your projects/packages inside of the GOPATH.
When you import a custom package, Go looks for its definition in each workspace listed in the GOPATH environment variable. Your custom package should be defined in a src subdirectory.
If you keep your code in a source repository somewhere, then you should use the root of that source repository as your base path. For instance, if you have a GitHub account at github.com/user, that should be your base path.
Note that you don't need to publish your code to a remote repository before you can build it. It's just a good habit to organize your code as if you will publish it someday. In practice you can choose any arbitrary path name, as long as it is unique to the standard library and greater Go ecosystem.
You should use github.com/user as our base path. Create a directory inside your workspace in which to keep source code:
$ mkdir -p $GOPATH/src/github.com/user
You can look at How to Write Go Code for more details.
The default orange tutorial folder is the following:
..\Canopy32\User\Lib\site-packages\Orange\OrangeCanvas\application\tutorials\
What if I want to change this location? Or add another folder?
Also would it be possible to achieve this by simply having a configuration file inside OrangeWidget folder?
Help please,
Many thanks.
You cannot change the default location of tutorials, but you can add additional tutorial folders using entry point in setup.py.
First, you need to create a python package containing schema (ows) files. Then you need to add an entry point in the setup.py pointing to the location of the package you have created.
If the package with custom tutorials can be imported using import my_tutorials, your entry_point will look like this:
ENTRY_POINTS = {
'orange.widgets.tutorials': (
'my_tutorials = my_tutorials',
),
}
I have created a sample add-on that registers additional tutorials. It is available on github:
https://github.com/astaric/orange-custom-tutorials-example
If you download the code and run python setup.py install, you will see a new entry in the tutorials.
Go, Golang : does not make sense that I have to have files before import
I am trying to go to next step but keep getting errors
I have the package that I want to import ready.
All I need to do is to import the external package from github and be able to use it on any code.
So this is what I did.
mkdir $HOME/go
export GOPATH=$HOME/go
go get github.com/user/project
This runs successfully. I downloaded it onto here with source code files from github
/Users/user/go/src/github.com/user/project/project.go
So to use this package that I just import I do
go run /Users/user/Desktop/code.go
But I am getting the following errors
MacBook-Air:~ user$ go run /Users/user/Desktop/code.go
Desktop/code.go:32:8: cannot find package "project" in any of:
/usr/local/go/src/pkg/project (from $GOROOT)
/Users/user/go/src/project (from $GOPATH)
What should I do? AM I missing something? Thanks in advance and please help me. I wrote a lot of code but being very frustrated not being able to distribute it because of this.
The error message says at line 32 in your code.go it can't find package "goling".
Assuming that is a local package you want to use, you need to make sure it is in your GOPATH.
If you set GOPATH then you should develop your code within it, so moving the "goling" directory into /Users/user/go/src is the right thing to do.
Alternatively "goling" could be a typo, so check the imports in code.go. If you want to import an project from github the import should say
import "github.com/user/project"
And you then use the parts of project with a prefix of project.
If that doesn't help you get it working, then post the imports section of code.go.
It looks like you've got the external package in the same folder as your main package which uses it. In go, all packages must be in separate directories. It looks like the github project itself is actually doing that. If you separate the packages into different directories it should work properly.
