Anaconda prompt finds libraries cmd python doesnt python was only installe

When working with Python, it is common to encounter situations where certain libraries or packages are not found in the Anaconda prompt, but are found in the regular command prompt. This can be quite frustrating, especially if you have already installed the necessary libraries using Anaconda. In this article, we will explore three different ways to solve this problem and determine which option is the best.

Option 1: Adding Anaconda to the System Path

One possible solution is to add the Anaconda installation directory to the system path. This can be done by following these steps:

  1. Open the Anaconda prompt.
  2. Type where python to get the path of the Python executable used by Anaconda.
  3. Copy the path obtained in the previous step.
  4. Open the regular command prompt.
  5. Type setx PATH "%PATH%;[path_to_anaconda]", replacing [path_to_anaconda] with the path copied in step 3.
  6. Restart the command prompt.

After following these steps, the regular command prompt should be able to find the libraries installed using Anaconda.

Option 2: Activating the Anaconda Environment

Another option is to activate the Anaconda environment in the regular command prompt. This can be done by following these steps:

  1. Open the regular command prompt.
  2. Type conda activate [environment_name], replacing [environment_name] with the name of the Anaconda environment you want to use.
  3. Once the environment is activated, you can use Python and import the necessary libraries as usual.

By activating the Anaconda environment, you ensure that the libraries installed in that environment are available in the regular command prompt.

Option 3: Using the Full Path to the Python Executable

If the previous options do not work, you can try using the full path to the Python executable in the regular command prompt. This can be done by following these steps:

  1. Open the Anaconda prompt.
  2. Type where python to get the path of the Python executable used by Anaconda.
  3. Copy the path obtained in the previous step.
  4. Open the regular command prompt.
  5. Type the full path to the Python executable followed by the script you want to run. For example, [path_to_python] script.py.

Using the full path to the Python executable ensures that the correct version of Python is used, along with the libraries installed using Anaconda.


# Python code goes here

After exploring these three options, it is clear that the best solution depends on the specific situation. If you frequently encounter this issue and need to use libraries installed using Anaconda in the regular command prompt, adding Anaconda to the system path or activating the Anaconda environment are good long-term solutions. However, if you only need to run a script once or twice, using the full path to the Python executable may be the quickest and easiest option.

Ultimately, the choice between these options will depend on your specific needs and preferences. It is recommended to try each option and see which one works best for you.
