I am trying to install a plugin for the Spyder ide called spyder-unittest (description here).
I am using:
MacOS X Version 10.14.6
Anaconda Navigator 1.9.7
Spyder 3.3.6
Python 3.7
After a first attempt using the command
conda install -c spyder-ide spyder-unittest
the plugin did not work (i.e. the additional command Run unit tests was not available under the Run menu).
I also tried, without success:
conda install -c conda-forge spyder-unittest
I then uninstalled and installed once again Anaconda navigator, and tried conda install -c spyder-ide spyder-unittest. This time, I got a very lengthy output, indicating conflicts (please see image):
Now, I do not know what to do. Could someone please offer any help?
I also tried to install after going, through the Terminal, to the directory where I thought the Spyder plugins were installed. Same output as above.
Thank you very much in advance.
Cheers,
Orlando
I managed to install spyder-unittest without any errors on my computer.
I suggest creating a new environment to avoid any conflicts with other packages when installing.
First create a new environment using:
conda create --name env python=3.7
After creating the environment, activate it using conda activate env
Then install spyder-unittest using conda install -c conda-forge spyder-unittest
I successfully installed pytorch via conda:
conda install pytorch-cpu torchvision-cpu -c pytorch
I also successfully installed pytorch via pip:
pip3 install https://download.pytorch.org/whl/cpu/torch-1.0.1-cp36-cp36m-win_amd64.whl
pip3 install torchvision
But, it only works in a jupyter notebook. Whenever I try to execute a script from the console, I get the error message:
No module named "torch"
Try to install PyTorch using pip:
First create a Conda environment using:
conda create -n env_pytorch python=3.6
Activate the environment using:
conda activate env_pytorch
Now install PyTorch using pip:
pip install torchvision
Note: This will install both torch and torchvision.
Now go to Python shell and import using the command:
import torch
import torchvision
I installed on my macos by the official command:
conda install pytorch torchvision -c pytorch
but when I follow the official verification I get the same problem like yours.
Then I create a conda virtual environment:
conda create --name learnpytorch python=3.5
and install pytorch inside the environment:
conda install pytorch torchvision -c pytorch
run the verification, it works.
Hope these could help you.
If you are using Anaconda Prompt, there is a simpler way to solve this.
conda install -c pytorch pytorch
You need to add this at the very top of your program
import torch
If this is not a problem execute this program on both Jupiter and command line and pretty much you will understand if you have a mismatch.
import sys
print(sys.executable)
I had the same problem right after installing pytorch from the console, without closing it and restarting it.
By restarting the console and re-entering my env, I solved the problem
Make sure that NumPy and Scipy libraries are installed before installing the torch library that worked for me at least on windows.
Install NumPy: pip install numpy
Install Scipy: pip install scipy
Go to pytorch.org and select your needs and copy the address
Paste the address and download
Usually if the torch/tensorflow has been successfully installed, you still cannot import those libraries, the reason is that the python environment you try to import is not the python environment you installed.
For example, if you have installed the torch/tensorflow using python='/usr/bin/python', then you cannot import them to python='/home/usrname/.../bin/python'.
The solution is simple thus, just change the python and import again.
Switch to python3 on the notebook
Welcome to SO,
please create a seperate conda environment
activate this environment conda activate myenv and than install pytorch in it.
Besides you can check which python you are currently using by which python
I had the same problem after following the official installation guide in here. I realized that it was my stupid Atom built-in terminal.
Inside the atom terminal, which python returned /usr/bin/python, although it showed the mark of (conda_env)$.
I fixed it by opening a new terminal and activating the (conda_env), and it worked. Verified and which python yields /Users/my_usr/anaconda3/envs/conda_env/bin/python
The procedure I used is specific to Windows 10 PyTorch installation on anaconda.
Create a conda virtual environment using: conda create -n torch_env
Activate virtual environment using: conda activate torch_env
When I installed, this was my current config: conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch.
Please find correct configuration according to your system settings from pytorch website directly: https://pytorch.org/get-started/locally/
Run python with import torch command. It should definitely work!
If you are using conda, it's possible that your console is using a different version of python, and the packages you installed using conda are not installed on this version. In my case, I installed a 3.9 version by downloading from the website, and conda installed a 3.8 version. And all the packages only installed for 3.8. Deleting the 3.9 version did the trick for me.
I'm using Jupyter Notebook launching from Anaconda Navigator 2.3.2 (Windows 10) to investigate pyTorch in a new Environment created in Navigator. Before launching I added pyTorch via a Command Prompt with the new Environment activated using the following which I got from pytorch.org:
conda install pytorch torchvision torchaudio cpuonly -c pytorch
I then ran into the No module named "torch" issue and spent many hours looking into this. I was eventually able to fix this issue looking at the results of this:
import sys
print(sys.path)
For me, this showed that the path to site-packages for my kernal (aka Environment) was missing. So I edited the kernal's kernal.json file found in:
<DRIVE_LETTER>:\Users\<USER_NAME>\AppData\Roaming\jupyter\kernels\<KERNAL_NAME>
To include an env section, which adds to PYTHONPATH like:
{
"argv": [
"<ANACONDA_INSTALL_DIR>\\envs\\<KERNAL_NAME>\\python.exe",
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"env": {
"PYTHONPATH": "..\\..\\..\\Users\\<USER_NAME>\\<ANACONDA_INSTALL_DIR_NAME>\\envs\\<KERNAL_NAME>\\Lib\\site-packages"
},
"display_name": "<KERNAL_NAME>",
"language": "python",
"metadata": {
"debugger": true
}
}
Please note that in my case I had to go back up 3 directories to the root of the drive, hence, the ..\\..\\..\\ at the start of the PYTHONPATH entry. You might need to change that. Also if you try to use a full path, to your Environment's site-packages, then it will prepend the current contents of PYTHONPATH to it instead of adding it as a separate entity.
I am struggling the above answer and it does not work in my case.
That is because I install the porch under window COMMAND PROMPT.
Installed under the Anaconda environment command prompt. To do that, type "anaconda" and select the ANACONDA COMMAND PROMPT (this is very important for me to fix my mistake)
Do the same command from: https://pytorch.org/get-started/locally/
Check SDK install. you also install the sdk in your environment.
You can install the SDK using navigator.
first, change tab to Environments,
second, push play button of your environment name.
Third, then install SDK.
If you are using windows and you have no CUDA, then go with the following command.
pip install torch==1.7.0+cpu torchvision==0.8.1+cpu torchaudio===0.7.0 -f https://download.pytorch.org/whl/torch_stable.html
You can visit its official site for more explanation.

If you are in the console, and importing a function that uses torch, you may need to add import torch within the function to allow for the correct scope. Because if you are importing the function, and there is no import statement at the top of the file, it won't work. Alternatively, make sure import torch is at the top of the module with the function you are trying to use, and within console, call the function using: your_module.function_that_references_torch()
Using Conda on win 10 running script from vs code terminal as:
$ script.py
Generates error:
ModuleNotFoundError: No module named 'torch'
The system goes outside the environment to execute call python.
This works:
$ python script.py
I tried to fixed the problem both in my laptop and computer, and it was fixed in different ways. You can try.
Laptop(Nvidia GTX 950M)
I fixed the problem by typing this under the environment that you install pytorch.
$ conda install pytorch torchvision cudatoolkit=10.0 -c pytorch
Remember to change the version(10.0) of you cuda
Computer(No GPU)
$ conda update -n base -c defaults conda
Most of the answers to this question are unsatisfying in that they explain how to create and activate a conda environment. The reason for the error is however not explained.
In my case, I had a conda environment set up, but the torch module was still not found, even if I installed it.
The reason for the error is that python v2 was the main interpreter, not python3.
You can test that by running python --version
Then follow the instructions from above to install the conda environment with the correct python version, e.g.
conda create -n venv python=3.9
I had an issue related to the path. Basically if I ran python with the path from which python, import torch works, if I just run python, it doesn't work.
This solution from #shoemakerdr on GitHub worked for me:
In your .bashrc, before the Conda initialize code, put unset CONDA_SHLVL
Create the environment:
conda create -n env_pytorch python=3.6
Install your modules. For example:
conda install pytorch torchvision cudatoolkit=10.2 -c pytorch
Next time you want to use pytorch:
conda activate env_pytorch
and when finished:
conda deactivate
I'm trying to create a Python 2.7 virtual environment with Anaconda so I can download some packages that are not compatible with Python 3.4. I'm working in Conda version 4.2.13.
When I type the command conda create -n chemistry python=2.7 anaconda the whole thing freezes at the solving package specifications stage.
Does anyone know what causes this or how I can go about fixing it?
Today I faced the same snag. It got fixed after updating my Anaconda Navigator.
Updating your Anaconda Navigator may fix your issue, too.
Try this:
conda create -n chemistry python=2.7
The initial command you use will try to install a package named anaconda. If you want to specify the channel when installing packages,you can add -c <channel>.For example:
conda install -c conda-forge tqdm
Had same issue while I was trying to install some packages. I tried updating python then all seemed working. Try it out
conda install python
Python 3.7 alpha version is out, but I haven't been able to find any post on how to update to python 3.7 using Anaconda - maybe they will wait for the official release? Any suggestions?
This can be installed via conda with the command conda install -c anaconda python=3.7 as per https://anaconda.org/anaconda/python.
Though not all packages support 3.7 yet, running conda update --all may resolve some dependency failures.
Python 3.7 is now available to be installed, but many packages have not been updated yet. As noted by another answer here, there is a GitHub issue tracking the progress of Anaconda building all the updated packages.
Until someone creates a conda package for Python 3.7, you can't install it. Unfortunately, something like 3500 packages show up in a search for "python" on Anaconda.org (https://anaconda.org/search?q=%22python%22) so I couldn't see if anyone has done that yet.
You might be able to build your own package, depending on what OS you want it for. You can start with the recipe that conda-forge uses to build Python: https://github.com/conda-forge/python-feedstock/
In the past, I think Continuum have generally waited until a stable release to push out packages for new Pythons, but I don't work there, so I don't know what their actual policy is.
To see just the Python releases, do conda search --full-name python.
The September 4th release for 3.7 recommends the following:
conda install python=3.7 anaconda=custom
If you want to create a new environment, they recommend:
conda create -n example_env numpy scipy pandas scikit-learn notebook
anaconda-navigator
conda activate example_env
run conda navigator, you can upgrade your packages easily in the friendly GUI
conda create -n py37 -c anaconda anaconda=5.3
seems to be working.
I am configuring Anaconda 1.9.1 together with Python 3.3.4 and I am unable to setup Matplotlib for anaconda environment when I try to add package using Pycharm. I also tried to install from Matplotlib.exe file which I downloaded from its website. I can not change the installation directory in that case. I would like to know that is there a way to tackle this issue.
If you're using anaconda, your default environment is Python 2.7. You need to create a new environment and install matplotlib in there.
In a command prompt, do the following (saying yes to the questions):
conda create --name mpl33 python=3.3 matplotlib ipython-notebook
activate mpl33
ipython notebook
You should be able to import matplotlib when the notebook server comes up.
The first command simultaneously creates the environment and install
the listed packages.
The second command activates the new environment by prepending its location to the system path
The third command just starts the ipython notebook so that you can test out everything
I don't know how pycharm works, but my guess is that you'll have to tell it to look for the right python that you want to use. In this case it'll be something like: C:/Users//anaconda/envs/mpl33. In any case, the command prompt should display the path when you activate the environment.
Once you've activated your environment, you can install more packages like this:
conda install pandas=0.12
conda install pyodbc statsmodels
You can specific version numbers of packages like the first command or simply accept the latest available version (default)
Assuming you've already installed a 3.x python env in anaconda, this one line should do the trick:
conda install matplotlib -n name
where name is the name you previously gave to your python 3 anaconda env. If you're not sure of the name you gave it, it will be the name of a subdir in the Anaconda\envs directory.
Background: I recently went through the same trouble with matplotlib not getting installed by default by anaconda when I added a full python 3 env, even though it's meant to. The above line solved it for me; it gave me the following warnings so it seems likely that the two different available versions caused it to initially install neither. However it allowed me to choose the one I wanted, and then everything worked great.
