I installed anaconda and started working on jupyter notebook.
When i try and import sklearn i get the error shown in the image (note that i didn't had any problems importing other packages).
I've done a bit of research online and from my understanding i believe the issue exists because i already have sklearn installed on Python and there's a possible conflict.
If that's the case i don't know what to do since i already use sklearn on another project and i cannot uninstall it.
Anyone know how i can solve this issue?
Thanks in advance!
As you can see from the traceback, there are two python environments involved here:
~\AppData\roaming\python\Python37
~\anaconda3
Please make sure your PATH is clean and you can actually remove one of them first.
For anyone that might face the same issue, check your Anaconda and Python.
I had Anaconda on 64-bit and i didn't knew that by default Python is downloaded on 32-bit.
After uninstalling and installing Anaconda to 32-bit everything worked fine
This is a very vague question but I am really stuck. I have been working with python for a little bit to try and use some of their functions in opencv (cv2) and other open source libraries. But whenever I try and use pip I will always get an error about improper installation or more commonly when trying to import the installed package idle throws an error that a line of code in the library that is causing an exception. This does not just happen to one library but nearly all of them (I have tried stuff like opencv, tensorflow, urllib). I have tried reinstalling different versions of python (multiple times) and reinstalling it but none of that seems to work. I don't know what to do but really want to be able to use these tools. I use windows 10 and use the default "User" user on admin.
Any help on possible options would be most appreciated!
This was happening to me as well.
In my case I wanted to work with Anaconda and Spyder. I was following some books and tutorials saying how to install stuff with the pip and so on, but it didn't work. What solved it was to install PyCharm and use those same pip functions directly on the PyCharm console (not the windows cmd). Then everything worked automatically and I have whatever library I installed from PyCharm available at Spyder without doing anything else.
Summary:
Get Pycharm -> link
use the same pip install directly in the PyCharm console
A-Hopefully it will work
If it doesn't: Can you elaborate on which IDE are you using? Most likely there is someone here who can help you.
I reinstalled it many times but nothing is solved , what should I do ?
Although this question is a little old, I have a possible solution.
In English the message is:
Unable to start the program because api-ms-win-crt-runtime-l1-1-0.dll cannot be found on your computer. Try to reinstall the program to fix this problem.
The problem is a little confusing because it's not really a python problem. It's a DLL that you need to re-install.
Simply put you don't have the api-ms-win-crt-runtime-l1-1-0.dll on your machine, or it is unregistered. You could try to re-register it, but it's easier just to do the following:
Run windows update.
Download Visual C++ Redistributeable: https://support.microsoft.com/en-us/kb/2977003
Run the installer and select "uninstall".
Run the installer again and select "install".
If Anaconda already fixed it for you, I hope this still helps someone somewhere sometime.
I am running into an Anaconda bug described in this Github issue: https://github.com/conda/conda/issues/2965
The reporter indicates that if we makes some changes to Anaconda, he can fix the problem. I have installed Anaconda on my Max (OS X 10.11.6), and I am having the trouble reported by this issue while following instructions to install TensorFlow. I'm wondering whether someone can tell me how to find and modify my Conda installation to test out the proposed bug fix listed in the issue? Also are there files I can simply modify or will I need to recompile or reinstall after? I am a newbie to this sort of thing, so any advice would be appreciated.
some months ago, I installed Python 2.7 on my laptop (my os is Windows 7).
After, I decided to use Python xy 2.7.3 instead of 'pure' Python; so, as suggested, I removed Python 2.7 and tried to install Python xy 2.7.3. However, when I tried to run the .exe file for installation, a warning window appears telling me that Python 2.7 is already installed on my computer. I tried to install a different version of Python xy (2.6) and everything went fine; however, I'd really prefer to use the latest version of Python xy.
Actually, I can't figure out what went wrong whie uninstalling Python 2.7; does someone have any clue?
I can tell you that I followed the 'normal' procedure for programm uninstalltion; control panel -> Programs -> Remove Program
Thanks in advance

Run regedit, backup and delete the registry keys:
HKEY_LOCAL_MACHINE\Software\Python\
HKEY_CURRENT_USER\Software\Python
My problem occurred when changing from Canopy to Python(x,y).
So, also delete all folders that are left behind when uninstalling.

I also had this issue as well. It was due to third party installs. Even though you have uninstalled python, it leaves all the third party libraries that were installed and I think Python(x,y) just detects the directory.
To fix, uninstall Python 2.7 and then check to see if C:\Python27 still exists. If it does, go ahead and delete and then try installing Python(x,y). That is what worked for me.
I faced this issue: I tried to uninstall the python and fresh install, reason my pip version issue was not getting resolved. So I deleted the python folder, removed python from system path, and when I tried to uninstall from "Uninstall a program" in control panel, it showed "Windows installation package" error window and could not clean uninstall.
Solution what i found was: In the "Uninstall a program" select python and click repair. And then uninstall the python, it worked for me. Hope this helps and save some time.
PS: I am pretty new to python, and any help correcting me would be appreciated.
Maybe to put an answer out there.
Uninstalling anything from windows can have multiple side effects residing completly on your specific machine. As to what is common:
-> Python sets itself in your windows path. Here is how to modify your windows path: http://www.computerhope.com/issues/ch000549.htm
It means that there is a probability that python is gone but the path entry might not be. That is a guess however -> more information needed
-> Are you sure that everything was removed from your computer? If you already did the normal uninstalling process - try to look up if any python directory is still present.
-> Thirdparty installed? Have you downloaded any libs that are still on your machine.
Besides from that - it could be anything - the more information you give us the more we can say about it.
Maybe this post will help you: How to completely remove Python from a Windows machine?
I had python 2.7.12 and wanted to uninstall it for 2.7.9. I had the same problem as you and to fix it I tried to delete all of the local files and then uninstall however it still gave me the same error. So instead I decided to repair the python 2.7.12 and then uninstall which worked perfectly and completely got rid of the error.
I had python 2.7 installed and enthought canopy. I wanted to switch to python(x,y) to access a full version of the OpenCV library. python(x,y) installation complained about python 2.7 already being installed after:
1)Using windows control panel
2)Removing all lingering python files
3)Removing the windows path as suggested above
Not until I removed all registry entries related to python/enthough did python(x,y) install without issue.
I installed Enthought before. When I wanted to install Python(x,y) instead, I met the problems above.
After I had tried to uninstall Enthought and Python(x,y) from the Control Panel and then restart the PC, the problem still occured the next time I installed Python(x,y).
I solved this problem by:
deleting all the relevant files in C:/User/UserName/AppData/ about Python, including the third party softwares like Enthought;
deleting the Path in user and system Environment;
=====the two steps were failed if I didn't do the third step.=====
deleting the register keys as #Daniel said. (include all the relevant keys with the prefix py if you installed the third party software about Python. )
HKEY_LOCAL_MACHINE\Software\Python\
HKEY_CURRENT_USER\Software\Python
Locate that set up file which was used to install Python. Run it and choose repair. If that doesn't solve the problem. Go to c:\Python(x,y) and delete this folder completely by shift+Del.
Run that set up file again and click on "Change" which will ultimately install the Python again. By default in my case option to add path and making that version of Python the default on my system was unchecked which can be figured out by seeing the red cross mark in one of the installation screen. Click on it if you want set up to make it default Python version and also click on the option to indicate you want the path to be added in windows environment variable.
No need to touch registry as previous ones will be overwritten again.
In my case it worked. I was getting error like:
Fatal Python error: Py_Initialize: unable to load the file system codec
LookupError: no codec search functions registered: can't find encoding
Besides that un-installation was failing from control panel. So above steps solved all of my problem. Hope it helps.
I Repaired/Modified to install all the components for the Python
version I wanted to uninstall.
Once that was done, I clicked on Uninstall/Change and that uninstalled it for good.
