Xgboost: WindowsError: exception: access violation reading 0x0000000100000008

[lwclark]

I've installed XGB on two independent VMs, one running Windows 10 and the other running Windows Server 2013. On both installs, when testing with "python basic-walkthrough.py" or when trying to invoke XGB from a Jupyter notebook, execution halts with this exception:

WindowsError: exception: access violation reading 0x0000000100000008

I've tried starting the jupyter notebook from an administrative command prompt, with the same result.

Any advice welcome. Thank you.

To separate out python-related issues, you may build the xgboost executable and then try some CLI demo, e.g., https://github.com/dmlc/xgboost/tree/master/demo/binary_classification and see if the problem persists.

Got the same issues after installing on windows 10 using instructions I found here https://www.ibm.com/developerworks/community/blogs/jfp/entry/Installing_XGBoost_For_Anaconda_on_Windows?lang=en.

Fixed the issue by moving the path reference for MinGW-W64 to the front of the PATH system variable.
Cleaned, rebuilt and re-installed xgboost. Problem solved.

Hi ,I am still facing the same issue. I tried to move path reference to front but of no use. Can you please help me with this? I have installed xgboost using link by emuchogu.

please find below error in ipython console

I know that error is something related to c++ and c. But i am not able to figure out the actual issue.

Thanks for responding.

I encountered the exception: access violation reading 0x0000000100000008 when using the .fit() method of the XGB classifier.

None of the solutions here, or elsewhere helped me.

Finally the only thing that worked for me was running my scripts (or executing jupyter notebook) on Windows command line (cmd) rather than git-bash.

Hope this helps you

I also find this problem during working in the windows using the cmd terminal for using the LightGBM(like the XGBoost). I try many ways for solving that, but finally if I delete the lgb_train and lgb_test and make the Datasets again, that will make it model start to train.
