Module not found error in VS code despite the fact that I installed it

Question

I'm trying to debug some python code using VS code. I'm getting the following error about a module that I am sure is installed.

Exception has occurred: ModuleNotFoundError
No module named 'SimpleITK'
  File "C:\Users\Mido\Desktop\ProstateX-project\src\01-preprocessing\03_resample_nifti.py", line 8, in <module>
    import SimpleITK as sitk

I installed the module using

sudo pip install SimpleITK

I know that it was installed because I was getting a similar error when I ran the code through the command line, and it was fixed by doing the above. I don't understand why VS code does not recognize that

Answer 1

sudo pip install is most likely installing globally into a Python interpreter that is different than the one that you have selected in VS Code. Please select the Python interpreter you want to use and then install explicitly using that interpreter (if you're not using a virtual environment then use something like /path/to/python -m pip install SimpleITK , although I strongly recommend using a virtual environment and to not install packages globally).

Answer 2

After install new module with pip if vscode not recognize it, reloading vscode may work.

• Ensure that the module installed inside virtual environment

Create and activate virtualenv

python3 -m venv env
source env/bin/activate

Use correct way of install module with pip

python3 -m pip install {new_module}

Replace "{new_module}" with your module name.

• Reload vscode: Ctrl + Shift + P , select Reload window

Now vscode will know new module and autocomplition works.

In Mac, correctly selecting the Python Interpreter worked for me:

From within VS Code, select a Python 3 interpreter by opening the Command Palette (⇧⌘P), start typing the Python: Select Interpreter command to search, then select the command. You can also use the Select Python Environment option on the Status Bar if available (it may already show a selected interpreter, too):

No interpreter selected

The command presents a list of available interpreters that VS Code can find automatically, including virtual environments. If you don't see the desired interpreter, see Configuring Python environments.

我在 VSCode 中遇到了这个问题，并通过以下过程将 VSCode 中的 Python 解释器设置为与系统路径中的解释器相同（在 Windows 上键入“echo %PATH%”并查找 Python）来解决它： https：/ /code.visualstudio.com/docs/python/python-tutorial#_select-a-python-interpreter

Answer 5

This error: your vscode use other python version. This solution change vscode use current python.

1. In terminal find current python version:

   py --version

2. In vscode Press Ctrl+Shift+P then type:

   Python: Select Interpreter

3. Select current python version

Answer 6

There are a lot of proposed answers that suggest changing the launch.json or the settings.json file. However, neither of these solutions worked for me.

My situation:

1. Is Python environment selected? yes
2. Does the Terminal recognize Python environment? yes
3. Can I run the Python code from the activated Terminal? yes
4. Does the code run w/o error when I use "Start Debugging"? yes
5. Does the code run when I click "Run Code"? no

The only solution that worked for me is to:

1. Open Windows Terminal (or cmd)
2. Activate environment: conda activate <environment_name>
3. Open Visual Studio Code from Terminal: code

Then, "Run Code" (#5) works without any issues.

Answer 7

Try running pip list in VS Code to check if the module is installed, next check if your python version is correct/supports that version of SimpleITK. It may be a problem with the python interpreter that you are using for VS Code (ie. the module may be installed on a different python instance than the one your VS Code is using)

Answer 8

Is Python environment selected? Does the Terminal recognize the Python environment? Can I run the Python code from the activated Terminal? Does the code run w/o error when I use "Start Debugging"?

if the answer to the above is "yes."

Then, Try running the Code using the option "Run python file in terminal" (in code runner extension). And assign a new shortcut for that for future use...

How to fix module not found error in Visual Studio code? To Solve VSCode ModuleNotFoundError: No module named X Error Make sure you are running from the package folder (not from package/module ) if you want import module. calculations to work. You can also set the PYTHONPATH environment variable to the path to the package folder.

I just ran into the same issue. I found that if I selected all text before shift enter the script would compile as a file instead of as a single line.

Answer 11

I had the same problem. I bet you have a shebang statement at the top of your file. If you do.

1. Visual Studios settings
2. Under "Code-runner->Code-runner: Respect Shebang" section or just do a search for "Code-runner: Respect Shebang"
3. Uncheck weather to respect Shebang to run code.

Now it will run under the virtual environment and find the modules that you installed using pip! :)

Answer 12

I struggled with this for a very long time, and had tried almost every other answer. I wasn't using pip , so that wasn't the issue. But still VS Code wasn't finding the modules that were installed in the Selected Interpreter.

Ultimately it came down to old conflicts that existed because I switched to miniconda, and VS Code was still looking for anaconda3.

I completely wiped VS Code and its associated files (cache, preference files, etc.) from my machine ( some instructions ), and installed a clean version.

This now syncs as expected with miniconda.

Answer 13

If you have different python versions installed, be sure you install module with right one.

python -m pip install <module>

or

python3 -m pip install <module>

Answer 14

Run your environment from a directory not in the users directory. I solved my problem running my environment from C:\Code\ProjectA\

I discovered my problem by running:

IMPORT os

Mycwd = os.getcwd()
PRINT(Mycwd)

Answer 15

.venv/Lib/SitePackages is the default directory where Vscode looks for Modules.

This directory is automatically created on creating .venv via the command Pallete .

External modules installed via pip are placed in this directory by default.

Place self created modules inside this folder manually.

Answer 16

Faced similar issue and here is how I fixed it. Remember that there are multiple ways to run your code in VS code. And for each way you may end up with different interpreters and environments. For example:

---

1. Creating virtual env and installing libraries

• In my case I opted into creating virtual environment and doing so outside of VS Code using command prompt:
  python -m venv.plotting_test
  

• Following that I activated it:
  .plotting_test\Scripts\activate.bat

• Following that I installed additional libraries:
  python -m pip install matplotlib

• Following that I made sure to see it was all installed ok:
  python -m pip list
  

• And I also checked where for current directory:
  cd
  

---

2. Point VS Code & VS Code Code Runner to virtual environment

• Opened vs code, closed previous workspaces, opened new folder, created test.py as I was starting new. Pressed ctrl + shift + p . Selected ```Python: Select Interpreter``:
  

• Followed by + Enter interpreted path
  

• Navigated to directory from last step from section 1. Found my virtual environment folder created in step one and pointed VS code to that version's python.exe in Scripts:
  

• Verified I am pointed to such:
  

• Saved as workspace so that I can create default workspace settings for this project:
  

• In workspace settings files defined paths to my virtual environment created n step 1 for workspace interpreter & CODE RUNNER(:):
  

    "settings": {
            "python.defaultInterpreterPath": "C:/Users/yyguy/.plotting_test/Scripts/python.exe",
            "code-runner.executorMap": {"python": "call C:/Users/yyguy/.plotting_test/Scripts/activate.bat && python -u"}
    }
}

• Reloaded window just to make sure (ctrl + shift + p) = "Developer: Reload Window"

• Now run code and run python file should be execute under your specified envs:
  

Answer 17

Once you have created a virtual environment, and installed your required packages in that environment, close VS code. For Windows platform, open command prompt and navigate to the folder where your virtual env folder is created. And then launch VS code from there using the command code.

For ex: My virtual env name is.imgenv, and its inside C:\py_stuff\projects So, I navigate to C:\py_stuff\projects and then type code.

Now, your VS code should recognize the packages !

I have the same situation as datalifenyc mentioned in https://stackoverflow.com/a/65917685/2993624 For me "Run Code" works if I open VS Code from the same terminal session. Otherwise, I have to use "Run Python File" instead.
