I am new to neo4j and have "0" coding background (although trying to learn some). I understand the basic functionalities and am also able to import nodes and relationships using LOAD CSV. However, I absolutely can not make the neo4j-admin import tool work.
I created a new database, included the simplest CSV file in the import folder and tried the following (I will have to explain in the most simple terms - so don't laugh :))
Name of the file is test.csv
Content;
PropertyTest,:LABEL
proptest,TEST
I tried running the neo4j-import file by trying to open it. A black screen opens up and immediately disappears.
I tried ---> bin/neo4j-admin import --id-type=STRING \
--nodes:TEST=test.csv \
--nodes="test.csv" \
Could someone please explain to me with the simplest terms what the steps would be to import this?
Thank you.
The import folder under your Neo4j installation is fine to use but just bear in mind that the dbms.directories.import setting in neo4j.conf is just for the LOAD CSV command, not for neo4j-admin import.
Since your current directory in the command prompt is the bin folder, when you run the import command specifying import/movies.csv then that implies that the CSV file is in a folder called import under the current directory, under the bin folder.
If you run the command this way it should find the CSV files:
neo4j-admin import --nodes=../import/movies.csv --nodes=../import/actors.csv --relationships=../import/roles.csv
.. means the parent directory so running the command this way means to go up to the parent directory and then into the import directory under the parent dir.

Hi guys I have a problem. I cant import my module "browser.py" because i cant load my third directory (here: "enums1").
Everytime I enter the dot after the directory "whatsapp", only par, not and main are shown as the only options.
Load Directory
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 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
Does anybody know how to import the data from GraphenDB into a local DB? The export from graphendb.com gives a zip file with a lot of files. I am not sure how to import those into a local instance of neo4j. Below are some of the contents from the zip folder:
Copy the contents of that zip file into path/to/neo4j/data/graph.db in a local instance of Neo4j. Then restart the Neo4j server.
Or, if you are using the desktop Neo4j application, just click "Choose" and point it to the extracted archive.
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.
