Why is python setup popping up when I start Pycharm and where is my python interpreter?

When I start Pycharm, this python setup menu pops up.
Python 3.7.4 is not even the version I'm using. Everything else works fine and I can just close it, but it is annoying.
There was a same question, and the answer was
You appear to be using the installer .exe as if it were the Python interpreter. Install Python to somewhere first, then use the python.exe in the bin directory inside that.
But I can't find where my bin directory is. My Python37-32 folder looks this.
How do I find my python interpreter?

Open some project -> File -> Settings -> Project: ... -> Project Interpreter -> Show All ... to view the list of available interpreters added to PyCharm.
Find and remove the interpreter which is pointing to Python distributive from the newly opened list.
At some point in past you added Python installer as a project interpreter in PyCharm so now when IDE tries to use this exe to run some background tasks (e.g. to get sys.path) installation wizard is triggered instead.
Correct python.exe to point PyCharm to is right on your screenshot

According to official python documentation.
The Python interpreter is usually installed as
/usr/local/bin/python3.8 on those machines where it is available;
putting /usr/local/bin in your Unix shell’s search path makes it
possible to start it by typing the command:
Since you are using Windows here, you are already in the location where the python interpreter resides. So look no further.
By the looks of the screenshots, I have a concern whether you have installed python correctly.
If you did not select the checkbox for Add Python 3.7 to PATH, the wizard expects you to do it manually which is why the error.
I would uninstall and reinstall Python and this time make sure to check that box. I am sure your error messages should go away.
Alternatively, if you're not in the disposition to uninstall. According to python docs here you can set the python variable to PATH variable and try.

PyCharm doesn't detect interpreter

I'm new to programming and just started a course on Python. I want to use PyCharm, so I downloaded and intalled it (v. 4.5, community edition). I had previously installed Python 3.5 64-bit from python.org (I'm using Windows 10).
To start using PyCharm, I need a project interpreter, which I can select in the settings. As far as I'm concerned, the interpreter is "py.exe", but when I select it, I get this error message: "The selected file is not a valid home for Python SDK". I also tried to use every file whose name contained "python" or "py", and failed.
On every website and video I see, they select a file called "python.exe", but they're using Python 3.4 or a previous version. I checked that PyCharm supports 3.5 ("Initial support for Python 3.5").
Is there anything I'm doing wrong? What should I do to be able to use PyCharm?
All replies are appreciated. Thanks in advance.

file > new project settings > project Interpreter > click in the drop down and select 'show all' > click the '+' button >
Now, in the Virtualenv Environment tab under the New environment radio button, check the path in the 'Base interpreter:' field. For me, mine was set to an invalid path. Once I had corrected the path to point to python.exe I recreated my new project and PyCharm built the virtualenv.
For me there was a bit more too.... When creating the new project I expanded the drop down and had to verify the directory where the venv directory was being created. Once I had corrected the path here I had to click around a bit to get it to let me create the project.
I'm going to chaulk this up to a bug. I'm using Community edition.

When creating a project in PyCharm, if the interpret is not already selected, in the drop down menu under the projects "Location:", you can click the gear-looking icon to the right of the interpreter option, and click "Add Local"; then select the file location of the python.exe file that you have installed. It will probably be C:\Python35\Python.exe

I faced a Similar issue and was not able to find Python interpreter anywhere on the system.
The problem with it was that python was installed directly with default settings and there was no exe found in
C:\Python35\
and to solve this i tried uninstalling and reinstalling with custom settings and selecting allow for all users as well which did the trick and path was set correctly to
C:\Python35\python.exe.
After whichPycharm was able to detect the interpreter on this path.

PyCharm project interpreter problem Resolved
I installed anaconda python distribution (Anaconda3-5.0.1-Windows-x86_64.exe) from the anaconda website. https://anaconda.org/anaconda/python
What it actually did was it re-installed my Python3.6.3 (pertinent to mention I have windows10, with pyCharm community & python 3.5 already but with the interpreter problem and while installing anaconda I chose the following settings and disabled my antivirus before my anaconda installation):
selecting allow for all users
installation path was set correctly and (stored safely for future)
restart my Computer after installation.(not essential-but I did)
opened Anaconda & Jet brian pycharm
selected new project in PyCharm screen shot of my New project default Python interpreter location = C:\Users\Skboy\PycharmProjects\dani Interpreter = C:\Users\Skboy\AppData\Local\Programs\Python\Python36-32\python.exe
Wow! my pyCharm started working for me,
Resolution : Python6.3 re-installation with proper custom setting
make a python test test1.py program file to print "hello python test world"
Run
now my Python Interpreter(automatically -by default select) Python 3.6.3
edit configuration & check for interpreter
(C:\Users\user1\AppData\Local\Programs\Python\Python36-32\python.exe)
Run
success test Run
worth to mention Anaconda Jupyter is a web based can also be used in case novice user are still having problems

I have had the exact same problem and was unable to find the solution until just now. Hopefully this works for anyone that was struggling with it.
I went to the location of the Python 3.5 (32-Bit) in my C: Drive which it turns out is just a shortcut to the actual Python application, right click on it and select Open file location which should direct you to the application version of python - simply called 'python'. This is the .exe file that PyCharm was looking for to use as the interpreter.
Now go to the configure interpreter menu in Pycharm and type in the file location of the actual python application. To get to mine I had to go to AppData/Local/Programs/Python/Python35-32. Click on the python.exe file and it should work.
This is my first post here so if its formatted incorrectly or doesn't use the conventional terms - sorry. Let me know if the solution worked for anyone else with the problem or if I fluked it.

If you kept the default settings while installing python, Your project interpreter for PyCharm will be:
C:\Users\yourUserName\AppData\Local\Programs\Python\Python36\python.exe
Chose the above location as your project interpreter inside PyCharm.
Depending on which python version you have, it could be either Python36\python.exe or Python35\python.exe.

For me the following solution it worked:
My configuration:
Pycharm Community edition 2019.1.1
Anaconda distribution with python 3.7. Interpreter in standard location.
Problem:
Pycharm was not able to find python interpreter after reinstallation of anaconda distribution.
Solution:
- Make sure you run pycharm as admin (right click and run as admin). This was actually the critical step.
- Create new project (or open an existing one)
- Depending on the choice choose interpter or go to file > settings > project interpreter > choose small gear on rights side > add > on base interpreter choose the 3 dots > paste the location of the interpreter in the anaconda distribution.
Hope it helped someone. For me the blocking point was that for some reason pycharm was not launching with admin rights.

Why isn't PyCharm's autocomplete working for libraries I install?

PyCharm's autocomplete isn't working for installed libraries. I have the following code:
from boto.emr.connection import EmrConnection
conn = EmrConnection(aws_keys.access_key_id, aws_keys.secret_key)
I want the editor to tell me what methods I have available to me when I press Ctrl+Space.
The boto library is installed in my environment, but it doesn't seem to be detected by PyCharm. How can I set this up correctly?

You've installed the 3rd-party library into a virtualenv, but PyCharm doesn't know about that by default. If nothing is specified, it will choose the system Python install as the interpreter. You need to go into the project settings and configure the interpreter to point at the virtualenv. PyCharm will then index the interpreter and allow you to autocomplete.
The virtualenv may be auto-detected in the dropdown menu on the left. If it is not, click the gear to the right, click "Add local", and select /path/to/virtualenv/bin/python (or \Path\to\virtualenv\Scripts\python.exe on Windows).

The above answer didn't work for me, because I wasn't able to find any project related setting in my setting,and the python Interpreter was empty.
The solution was to delete .idea file, from project root, close Pychram then go to project directory and open it with Pycharm:
$pycharm-professional or $pycharm-professional .
when it lunch a pop up window on the bottom right will appear and as you the following
select configure python interpreter then a new window must appear:
chose to use Pipenv as your interpreter or any other solution that is for your case.
Now the Project setting should appear again in Pycharm setting, and the recommendation must be already working.

PyCharm doesn't recognize my Python installation path

This is the same question as this else but for Python.
The thing is that I've built my own installer package of Python interpreter (I've added modules and extras) and once installed I can't find the way to set the location of my custom Python installation dir in PyCharm IDE, I can't find any option to manually specify the location of python interpreter.
While I don't know if exist that option I'm thinking in other alternative, If maybe the PyCharm IDE takes the original Python path from a registry value then it should be sufficient for set the location, but I don't know if pycharm uses a config file or a reg key to get the python location and where is this value to modify it, I need help.
PS: I'm having the same problem for RubyMine IDE.

For PyCharm, in the IDE go to File -> Settings. In the Project Settings navigation panel, select Project Interpreter and then Python Interpreters, then in the right panel, click on the green plus (+) icon on the top right and select local. Navigate to the python executable you would like to specify as your interpreter.

You can also try this:
click on File
select Settings from the menu
in new Settings window click on Project and then Python interpreter
click on gear icon on the right, then on Add... option
in the Add python interpreter window select System interpreter from the list on the left
pick Python, click apply and you are done

I was having similar problems with PyCharm.
Having installed both Python 2.7 and 3.5 I was only able to find the the "python.exe" file for python 2.7.
I tried reinstalling Python 3.5 and attempting to change the installation path to C:// but it lead to several errors. This is the work around I found for getting 3.5 on PyCharm as an interpreter.
Copy the python 3.5 directory in windows explorer.
Paste it into PyCharms choose local interpreter area.

How to select Python version in PyCharm?

I have PyCharm 1.5.4 and have used the "Open Directory" option to open the contents of a folder in the IDE.
I have Python version 3.2 selected (it shows up under the "External Libraries" node).
How can I select another version of Python (that I already have installed on my machine) so that PyCharm uses that version instead?

File -> Settings
Preferences->Project Interpreter->Python Interpreters
If it's not listed add it.

I think you are saying that you have python2 and python3 installed and have added a reference to each version under Pycharm > Settings > Project Interpreter
What I think you are asking is how do you have some projects run with Python 2 and some projects running with Python 3.
If so, you can look under Run > Edit Configurations

PyCharm 2019.1+
There is a new feature called Interpreter in status bar (scroll down a little bit). This makes switching between python interpreters and seeing which version you’re using easier.
Enable status bar
In case you cannot see the status bar, you can easily activate it by running the Find Action command (Ctrl+Shift+A or ⌘+ ⇧+A on mac). Then type status bar and choose View: Status Bar to see it.

This can also happen in Intellij Ultimate, which has PyCharm integrated. The issue is as diagnosed above, you have the wrong interpreter selected.
The exact method to fix this for any given project is to go to Project Settings...Project and adjust the Project SDK. You can add a New Project SDK if you don't have Python 3 added by navigating to the python3 binary. This will fix the errors listed above. A shortcut to Project Settings is the blue checkerboard-type icon.
You can also add Python 3 as the default interpreter for Python projects. On OSX this is in File..Other Settings...Default Project Structure. There you can set the Project SDK which will now apply on each new project. It can be different on other platforms, but still similar.

Go to:
Files -> Settings -> Project -> *"Your Project Name"* -> Project Interpreter
There you can see which external libraries you have installed for python2 and which for python3.
Select the required python version according to your requirements.

Quick Answer:
File --> Setting
In left side in project section --> Project interpreter
Select desired Project interpreter
Apply + OK
[NOTE]:
Tested on Pycharm 2018 and 2017.
