I installed detectron2 via anaconda: conda install -c conda-forge detectron2
The installation succeeded but i fail to run: detectron2.data import build_detection_train_loader
the error message is:
i wonder know what i can do to successfully run my code.
details of my conda environmnt:
I tried to re-install my pytorch, to make sure that its version is corresponding to torchvision
I just installed spacy on my conda environment, but when it is failing to import. I tried both pip install -U spacy and conda install -c conda-forge spacy.
As seen in the image, when i run the code python -m spacy info it detects spacy. Importing works in pycharm. Is this a jupyter problem?
I've been trying to install the Pytorch module for my Ubuntu 16.04 LTS through conda. I used conda install pytorch torchvision cpuonly -c pytorch to install it (non CUDA version). However when I type import torch on the Python shell, this is what I see -
ImportError: /home/student/anaconda2/lib/python2.7/site-packages/torch/_C.so: object file has no loadable segments
I have verified that Pytorch was installed using conda list
I had the same issue on Ubuntu 18.04 for conda env with python 3.8. The problem I think is for the incomplete torch installation. So I did pip install from wheel instead of conda install. You may follow as below (assuming you have cuda11 installed):
create conda env
conda create --name=myenv python=3.8
conda activate myenv
Install torch from wheel
pip install torch==1.7.0+cu110 torchvision==0.8.1+cu110 torchaudio===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
Please note I had to install torchvision==0.8.1+cu110 as reported here
After having upgraded my environment's python to Python 3.61, I attempted to install pytorch using this command:
conda install -c peterjc123 pytorch
However I got this error:
Fetching package metadata .............
Solving package specifications: .
UnsatisfiableError: The following specifications were found to be in conflict:
-pytorch
-pyqt
I also used the commands
conda install -c peterjc123 pytorch cuda90
conda install -c peterjc123 pytorch cuda80
But the result is still the same. Anyone got a clue how to solve this?
The problem was solved after downgrading from Python 3.6.2 to Python 3.5.1 after running:
conda install -c anaconda python=3.5.1
After running this command, run:
conda install -c peterjc123 pytorch
Pytorch should install as per normal. A similar issue occurs for openCV as well
An alternative way to install pytorch using anaconda is
conda create -n py_env python=3.5
source activate py_env
conda install pytorch-cpu torchvision -c pytorch
Go to python shell and import using the command
import torch
Hope this helps.
Can someone help me in installing python package "Prophet" on windows 10 .
I tried installing python 3.5 and the dependency 'pystan' but yet I get below error.
"The package setup script has attempted to modify files on your system that are not within the EasyInstall build area, and has been aborted.This package cannot be safely installed by EasyInstall, and may not support alternate installation locations even if you run its setup script by hand.Please inform the package's author and the EasyInstall maintainers to find out if a fix or workaround is available.
Command "python setup.py egg_info" failed with error code 1 in c:\users\suman\appdata\local\temp\pip-build-aqoiqs\fbprophet\"`
I spent a good two days on this issue, finally, I found the following solution
1) Download and install Anaconda 3 (for python 3.6)
2) Create an environment and call it whatever you like
3) Run that environment (which will open the command prompt)
4) follow the following steps in command prompt : (commands are shown in bold)
python -m pip install -U pip
Requirement already up-to-date: pip in c:\users\william\anaconda3\envs\testtime\lib\site-packages
conda install -c conda-forge pystan

pip install fbprophet
I also had several issues installing prophet on my Windows 10 machine using conda and Python 3.7.
The following steps made it work:
Create a fresh conda environment
Install pystan and other dependencies using conda install numpy cython matplotlib scipy pandas -c conda-forge (see https://pystan2.readthedocs.io/en/latest/windows.html#steps)
Install prophet using conda install prophet -c conda-forge
In then still had a numpy error Importing the numpy c-extensions failed... as described here: https://numpy.org/devdocs/user/troubleshooting-importerror.html But this was due to my IDE which is VS Code as I could successfully run my prohet model using the command line with the activated conda environment.
So please also make sure to test the installation from the command line in order to rule out that the error stems from you IDE.
Not sure if the same trick would work on Windows, anyways posting w.r.t what just worked on RHEL 7, f.w.i.w
Motivation was installing fbprophet using conda:
conda install -c conda-forge fbprophet
and, it could install pystan==2.17.1.0 and fbprophet==0.6
So, the trick was:
uninstall the pystan package when you had earlier run pip3 install fbprophet, basically one needs to execute the following:
pip3 install pystan==2.17.1.0
pip3 install fbprophet==0.6
And one can thereby import fbprophet in python3 terminal, so working :)
I currently have a fairly vanilla install of Python 3.5 on my Windows 10 machine that I setup using Anaconda.
I was able to install Prophet using the below command, that might work for you. Depending on how your installed Python you may need to run the below command in a cmd shell that was opened as administrator.
pip install prophet
Whenever I have tried to install fbprophet package multiple issues have come.I will suggest a few steps, hopefully they should work.
Close all existing Python / R running instances. If possible restart the machine. I have seen to work as few libraries / dependencies which I want to update might be getting used by existing running instances.
Use anaconda prompt.
First install pystan -
`conda install pystan`
Now install fbprophet
'conda install -c conda-forge fbprophet
Hopefully it should work for you. Also, ensure you have admin rights.
I faced the same issue and my solution was to:-
Create a new environment with Python3.5
conda create -n pht python=3.5 anaconda
Install Prophet using the command.
conda install -c conda-forge fbprophet
I didn't install 'gcc' although this was advised before installing Prophet.
