I want to use the open source person re-identification library in Python
on Ubuntu 19.04
with Anaconda
no CUDA
in the terminal PyCharm (or not)
Python version 3.7.3
PyTorch version 1.1.0
For that I have to follow instruction like on their deposite git :
git clone https://github.com/Cysu/open-reid.git
cd open-reid
python setup.py install
python examples/softmax_loss.py -d viper -b 64 -j 2 -a resnet50 --logs-dir logs/softmax-loss/viper-resnet50
I receive the following error:
from sklearn.utils.extmath
import pinvh
ImportError: cannot import name 'pinvh'
I have tried to create virtual environments with previous versions of PyTorch (0.4.1, 0.4.0 and 1.0.1) but I always got:
File "examples/softmax_loss.py", line 12, in <module>
from reid import datasets
ModuleNotFoundError: No module named 'reid'
I do not know how to fix it.
EDIT :
Hi thanks for the answer, the problem is that the import are like :
from reid import datasets
from reid import models
from reid.dist_metric import DistanceMetric
from reid.trainers import Trainer
from reid.evaluators import Evaluator
from reid.utils.data import transforms as T
from reid.utils.data.preprocessor import Preprocessor
from reid.utils.logging import Logger
from reid.utils.serialization import load_checkpoint, save_checkpoint
I tried :
from ../reid import datasets
But I got a
File "examples/softmax_loss.py", line 12
from ../reid import datasets
^
SyntaxError: invalid syntax
EDIT 2 :
After re-installing Python 3.7.3 and pytorch 1.1.0 the problem persist with pinvh... I still got this message :
ImportError: cannot import name 'pinvh' from 'sklearn.utils.extmath'
If you can tell me how to fix it or try to tell me if it works please
Since the directory structure is as below:
/(root)-->|
|
|-->reid |--> (contents inside reid)
|
|
|-->examples | -->softmax_loss.py
|
|-->(Other contents in root directory)
It can be observed that reid is not in the same directory as softmax_loss.py, but instead in the parent directory.
So, in the file softmax_loss.py, at line number 12 and below, replace reid with ../reid, this looks for the directory reid in the parent directory.
The other method is to use: import ../reid as R or any other variable; Then use from R import datasets, and so on
utils.extmath.pinvh was deprecated in scikit-learn version 0.19 and removed in version 0.21. The easy fix is therefore to use an earlier version of scikit-learn.

I'm trying test pylucene library. I have written this code only for import test. It doesn't work. I get

I have run python3.10 -m pip list and there is "lucene" module. if I import lucene work well but python doesn't recognize org module. Why?
UPDATE
I downloaded lucene 9.1 and set environment variable (/etc/environment):
CLASSPATH=".:/usr/lib/jvm/temurin-17-jdk-amd64/lib:/home/bigissue/all_lucene/lucene-9.4.1/modules:/home/bigissue/all_lucene/lucene-9.1.0/modules" export CLASSPATH
I downloaded pylucene-9.1.0 and I have installed it
first jcc
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$ pwd
/home/bigissue/all_lucene/pylucene-9.1.0/jcc
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$python3.10 setup.py build
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$python3.10 setup.py install
I downloaded also ant apache.
then pylucene 9.1
cd ..
I have edit Makefile
vim /home/bigissue/all_lucene/pylucene-9.1.0/Makefile
PREFIX_PYTHON=/usr/bin
ANT=/home/bigissue/all_lucene/apache-ant-1.10.12
PYTHON=$(PREFIX_PYTHON)/python3.10
JCC=$(PYTHON) -m jcc --shared

bigissue#vmi995554:~/all_lucene/pylucene-9.1.0: make
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0: make install
if I run python3.10 -m pip install | grep -i "lucene" I see it.
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$ python3.10 -m pip list | grep -i "lucene"
lucene 9.1.0
Now I have imported lucene
import sys
from os import path, listdir
from lucene import *
directory = RAMDirectory()
But I get
ImportError: cannot import name 'RAMDirectory' from 'lucene' (/usr/local/lib/python3.10/dist-packages/lucene-9.1.0-py3.10-linux-x86_64.egg/lucene/__init__.py)
Python doesn't use that kind of imports.
Just import lucene.
If this doesn't fix your problem, sorry!
You can use from lucene import whatever.
See the Features documentation, where it states:
"The PyLucene API exposes all Java Lucene classes in a flat namespace in the PyLucene module."
So, in Java you use import org.apache.lucene.index.IndexReader; but in PyLucene you use from lucene import IndexReader.
Update
Regarding the latest error you mentioned in the comments to your question:
ImportError: cannot import name 'RAMDirectory' from 'lucene'
Lucene's RAMDirectory has been deprecated for a long time - and was finally removed from version 9.0 of Lucene.
You can use a different directory implementation.
Recommended: MMapDirectory - but there are other options such as ByteBuffersDirectory
(Just to note, a new error/issue should really be addressed by asking a new question.)
I am trying to use the dygraphs plot function from [here] (https://github.com/dinkelk/PyDyGraphs) in my jupyter notebook. The documentation says to:
Installation
Simply clone this repository and include the dygraphs.graph module in >>your Jupyter Notebooks. Note: PyDyGraphs only supports Python 3.
The documentation says to use "import dygraphs.graph as dy"
I'm not sure where to put the repository once I've downloaded it.
The package I've downloaded and unzipped. I've included the "import dygraphs.graph" in my notebook.
This package requires pandas to be installed and imported which I have done.
import numpy as np
import dygraphs.graph as dy
_____
ModuleNotFoundError Traceback (most recent
call last)
<ipython-input-3-29a3c1e17595> in <module>
4 import pandas as pd
5 import time
----> 6 import dygraphs.graph as dy
ModuleNotFoundError: No module named 'dygraphs'
_____
I'm wondering where I should have put the files downloaded from github and if there is anything else I should be doing in order to use this package.
You need to add a system path (or install the package to the default python libary) before using "import dygraphs.graph". See the example .
Add something like this in your jupyter notebook:
sys.path.append("../")
Then change "../" to the relative path to "dygraphs" folder you downloaded.
I am new to ROS and python. This question could be silly but spent almost 5 hours on this. I am using PyCharm (Latest version) with Python 2.7.15 64 bit (Also tried with 3.x). I need to import a few libraries as below:
import roslib;
roslib.load_manifest('smach_tutorials')
import rospy
import smach
import smach_ros
However, PyCharm fails to identify roslib, rospy, smach and smach_ros (could not find in the interpreter also to import). The above libraries are example given in the official site:
http://wiki.ros.org/smach/Tutorials/Simple%20State%20Machine
OS: Windows 7 (64 bit)
ROS not installed: ("SMACH is a ROS-independent Python library to build hierarchical state machines" - from the official site)
Error Traceback:
Traceback (most recent call last):
File "C:/Users/****/Desktop/Python/TestCharm.py", line 3, in <module>
import roslib;
ModuleNotFoundError: No module named 'roslib'
If you are using the catkin version of ROS (Groovy and later), it does not use the manifest file but uses the package.xml file instead.
So your code will be:
import rospy
import smach
Apparently, your code is ready for ROS Fuerte or earlier version.
With supposing that Smach is ROS-independent, you need only to the import smach
Thanks for all the support. I found out it is not possible for my perticular case to use SMACH because it has dependency on catkin. I am using Windows 7 and should be upgraded to windows 10 or use Ununtu Linux.
Really sorry for my novice question.
I am trying to install a module in python for neo4j but I got an error.
here is the import :
from scripts.vis import vis_network
from scripts.vis import draw
Here is the error:
ModuleNotFoundError: No module named 'scripts'
I have tried "pip install scripts"
Thanks in advance
ModuleNotFoundError simply means the Python interpreter couldn't find the module. I suggest that you read about python modules and packaging here.
I have looked at the source code you pointed to and it works perfectly fine. I suspect your paths are not well set up.
Make sure that in you are running importing scripts.vis in app.py, the directory structure looks like this:
./scripts
./scripts/__init__.py
./scripts/vis.py
....
./app.py #in app.py, you can import as 'from scripts.vis import x'
Here's what it looks on my system:
app.py is successfully able to make the import from vis sub-module. You can use a IPython notebook, that should work fine too.
If you want to visualize the graph in the python environment (Jupyter), you can try using neo4jupyter library. Here you will use neo4jupyter.draw to visualize the graph.
Install !pip install neo4jupyter
For example:
import neo4jupyter
neo4jupyter.init_notebook_mode()
from py2neo import Node
nicole = Node("Person", name="Nicole", age=24)
drew = Node("Person", name="Drew", age=20)
graph.create(nicole | drew)
options = {"Person": "name"}
neo4jupyter.draw(graph, options)

Im trying to compile Godot engine following the instructions here
When I run scons bin/godot as the tutorial says, I get the following error:
scons: Reading SConscript files ...
ImportError: cannot import name _args_from_interpreter_flags:
File "/home/grayfox/github/godot2/godot/SConstruct", line 9:
import multiprocessing
File "/usr/lib64/python2.7/multiprocessing/__init__.py", line 65:
from multiprocessing.util import SUBDEBUG, SUBWARNING
File "/usr/lib64/python2.7/multiprocessing/util.py", line 40:
from subprocess import _args_from_interpreter_flags
The SConstruct file starts this way:
EnsureSConsVersion(0,14);
import string
import os
import os.path
import glob
import sys
import methods
import multiprocessing
...
If I try to run python SConstruct I get an error complaining about missing functions defined by scons (i.e. the script fails after doing all the imports).
Commenting import multiprocessing fixes the issue but I don't want to modify that file, as I would have to revert the change if I ever make a pull request. The project is quite active so I believe this has something to do with my local configuration.
Any ideas why the script is failing to import _args_from_interpreter_flags only if I execute it via scons?
[UPDATE]
I did a fresh Gentoo install and the problem persists. I did some tests and I found this:
In a python terminal>
>>> import SCons.Script
>>> from subprocess import _args_from_interpreter_flags
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name _args_from_interpreter_flags
>>> import subprocess
>>> subprocess.__file__
'/usr/lib64/python2.7/site-packages/SCons/compat/_scons_subprocess.pyc'
But the output is different if I do this:
>>> import subprocess
>>> subprocess.__file__
'/usr/lib64/python2.7/subprocess.pyc'
So I update my question: Is this a bug? Can anybody reproduce it in other distros? If it's a bug, should I report it to Gentoo or to SCons?
[ANOTHER UPDATE]
Adding temp.extend([os.path.join(x, 'lib64') for x in prefs]) did't work, same error.
Adding print sys.path at the beginning of the compact module gives:
['/usr/lib64/python-exec/python2.7/scons-local-2.3.0',
'/usr/lib64/python-exec/python2.7/scons-local',

It looks as if this isn't really a problem connected to SCons directly. You might have an alien "subprocess" module/package installed in your system. Also check out Cannot import name _args_from_interpreter_flags which seems to be related.
Based on your updated question: I tried to compile Godot on my machine (Python 2.7.3, SCons 2.3.1, Ubuntu 12.04 LTS) and it's running fine, so the problem is not related to the provided SConstruct (and its supporting build description files in subfolders). The "_scons_subprocess" module gets used only when the import of the original "subprocess.py" fails. So I suspect that the SCons start script sets up a wrong sys.path, which may happen under 64bit (see issue http://scons.tigris.org/issues/show_bug.cgi?id=2657 ).
After you added "temp.extend([os.path.join(x, 'lib64') for x in prefs])", your "print sys.path" statement shows paths like "/usr/lib64/python-exec" in its output. A Google search turned up the page http://forums.gentoo.org/viewtopic-t-985402-start-0.html for me. It describes an issue with Gentoo, where programs are installed as links to pip. Please follow the given advice and see if this fixes your problem.
It's a bug in Gentoo's scons-2.3.0 and scons-2.3.1 ebuilds (see bug report). It has been fixed in versions 2.3.1-r1 and higher.
