I installed xgboost in PythonAnywhere and it shows successful but when I import it in a script, an error is given which says, "No module xgboost found". What can be the reason?
You probably installed it for a version of Python that is different to the one that you're running.
In my case, I use Anaconda2 and installed xgboost through git. Everything was ok but I got this message while trying to use import xgboost:
No module xgboost found
When I run pip install xgboost I got the message that everything is ok and xgboost is installed.
I went on ../Anaconda2/Lib/site-package and saw a folder xgboost-0.6-py2.7.egg, and inside there was other one xgboost. I just copied this folder xgboost and pasted it inside ../Anaconda2/Lib/site-package. And now it works =)

I got a problem I can't seem to figure out. The first time I imported Spacy into a Jupyter notebook I had no problems. It just imported it as I expected.
The second time I tried to import it (using a different notebook) I got:
ImportError: cannot import name 'prefer_gpu' from 'thinc.api' (C:\python-environments\nlp\lib\site-packages\thinc\api.py)
So I tried to restart the kernel and tried it again (thinking that might be the issue). That did not solve it. Also trying to run the same cell that imported Spacy in the first notebook also throws the error now after it went well the first time.
It sounds like you have an old version of Thinc somewhere; try uninstalling and reinstalling Thinc.
Another thing to check is if you're running in the right Python environment. Sometimes Jupyter notebooks pull in a different environment than the one you're expecting in non-obvious ways. There was a thread in spaCy discussions about this recently. You can run this command to check which Python executable is being used in the notebook and make sure it's the one you think it is:
import sys
print(sys.executable)
I had a similar issue, followed the git hub link, created a new environment, and installed all required packages, and it resolved my issue. I'm using Visual code, so I had to install other dependencies since VC uses this as a conda environment as a base for my code implementation

I currently am trying to use XGBoost in a python project inside of PyCharm and it always will say that it is installed as is shown here, Showing Install,
and it shows confirmation here at the bottom but it is not listed in the package list. Then it is not available for use in my program. Any help with this is appreciated.
Confusion is probably caused by PY-29611 issue - PyCharm reported failed package installations as successful. The problem with PyCharm UI should be fixed in 2018.1.2, meanwhile, try to install XGBoost from the terminal to discover the real problem behind the failed installation.
I’m experimenting with XGBoost and am blocked by an error I can’t figure out. I have sklearn installed in the active environment and can verify it by training a sklearn RandomForestClassifier in the same notebook. When I try to train a XGBoost model I get the error XGBoostError: sklearn needs to be installed in order to use this module
This works:
clf = RandomForestClassifier(n_estimators=200, random_state=0, n_jobs=-1)
This throws the exception:
clf = xgb.XGBClassifier(max_depth=3, n_estimators=300, learning_rate=0.05).fit(train_X, train_y)
UPDATE: Created a PyCharm module with exactly the same code and imports and it executed without an exception. So this appears to be a Jupyter Notebook issue. PyCharm is pointed to the same Anaconda environment as the notebook.
UPDATE 2: Created a new notebook and copied the code from the one that was throwing the exception. The code runs OK in the new notebook. Sigh. Case closed.
Ran into the same issue, I had installed sklearn after installing xgboost while my jupyter notebook was running. By restarting my Jupyter notebook server, xgboost was able to find the sklearn installation.
Tested this in another fresh environment where I've installed sklearn before installing xgboost then starting my jupyter notebook without the issue.
I got the same error with a more complicated project, after releasing a new version suddenly it failed.
luckily in my case, I had docker images for each version, and was able to use pip freeze to see what changed.
In both version I used xgboost==0.81
In the version that worked I had scikit-learn==0.21.3 and in the new version it was scikit-learn==0.22
surprisingly enough, that's now what caused the issue. I've tried to uninstall and reinstall xgboost and reverted scikit-learn to the version is was originally on, and still no luck (even after making sure to install one after the other in the right order).
what did cause the issue was an update of numpy from 1.17.4 to 1.18.0.
reverting it solved it for me (not sure why)
this was python 3.6 on ubuntu
I had the same issue. All the already given answers did not work. I tried downgrading numpy versions as well, as it was said to work at some other forum
I eventually reinstalled Anaconda and then installed pip installed xgboost again. This worked.
If you have the correct version of xgboost and sklearn. Then after installing on Jupyter notebook. you will see it is not working just restart your jupyter notebook. I solved using this way from this source:

I am trying to download the Pygraphics module using Python 2.7.6 and have been heretofore unsuccessful. Below I detail the steps I have taken so far. Any help with this would be most appreciated.
First, I tried the typical install using pip
sudo pip install Pygraphics
When I try to import the module, I receive an error saying ImportError: No module named Pygraphics.
To test whether the module was installed I ran the following code: print sorted(["%s==%s" % (i.key, i.version) for i in pip.get_installed_distributions()]) which showed me all of my installed distributions.
This code returned the following list of all the distributions and clearly showed that Pygraphics is installed:
['altgraph==0.10.2', 'bdist-mpkg==0.5.0', 'bonjour-py==0.3', 'brewer2mpl==1.4', 'certifi==14.05.14', 'datetime==4.0.1', 'flask==0.10.1', 'ggplot==0.6.5', 'ipython==2.0.0-dev', 'itsdangerous==0.24', 'jdcal==1.0', 'jinja2==2.7.3', 'macholib==1.5.1', 'markupsafe==0.23', 'matplotlib==1.4.x', 'mock==1.0.1', 'modulegraph==0.10.4', 'nose==1.3.4', 'numpy==1.9.0.dev-297f54b', 'openpyxl==2.1.2', 'pandas==0.14.1', 'pandasql==0.6.1', 'patsy==0.3.0', 'pika==0.9.14', 'py2app==0.7.3', 'pygments==1.6', 'pygraphics==2.1']
After this, I tried using the GUI installer located on the following Pygrahpics install website. While going through the installer, I received an error message saying "PyGraphics requires System Python 2.7 to install" despite the fact that I have downloaded Python 2.7.6.
At this point I don't know what to do and was hoping someone who may have had a similar issue might be able to help me out.
Thank you for your time.
It looks like you've successfully install PyGraphics. Now import picture :)
