My Jupyter notebook's python kernel keeps dying. I have run all of the following code successfully before. Presently, there are issues. First, I will show you the code chunk that I am able to run successfully:
import xgboost as xgb
xgtrain = xgb.DMatrix(data = X_train_sub.values, label = Y_train.values) # create dense matrix of training values
xgtest = xgb.DMatrix(data = X_test_sub.values, label = Y_test.values) # create dense matrix of test values
param = {'max_depth':2, 'eta':1, 'silent':1, 'objective':'binary:logistic'} # specify parameters via map
where my data is small:
X_train_imp_sub.shape
(1365, 18)
however, my notebook's kernel keeps dying on this chunk:
xgmodel = xgb.train(param, xgtrain, num_boost_round = 2) # train the model
predictions = xgmodel.predict(xgtest) # make prediction
from sklearn.metrics import accuracy_score
accuracy = accuracy_score(y_true = Y_test,
y_pred = predictions.round(),
normalize = True) # If False, return # of correctly classified samples. Else, return fraction of correctly classified samples
print("Accuracy: %.2f%%" % (accuracy * 100.0))
When I break it apart and run line-by-line, the kernel appears to die on the xgb.train()
line.
The data is small. The xgboost parameters should be conservative (i.e. num_boost_round = 2
, max_depth:2
, eta:1
and not computationally expensive. Not sure what is going on.
As stated before, I have been able to run both chunks successfully before. I have shut down all other notebooks and restarted my computer without luck. I am launching jupyter
through Anaconda Navigator on a Macbook Pro.
-- UPDATE --
When I selected a cell beneath my xgboost
training cell, then selected: Cells
--> Run All Above
, the kernel would always die on the xgboost
training line. This happened ~40-50 times in a row. I tried that many times because I was making changes to the code, thinking I would resolve the xgboost
issue later.
Later on, I ran the same cells one-by-one and the xgboost
completed fine on the first time I tried this and every time after. I do not know why this happens but it would be nice to know.
I was having a similar problem. This fixed it for me.
import os
os.environ['KMP_DUPLICATE_LIB_OK']='True'
from xgboost import XGBClassifier
I had the same issue. The stupid thing is it was working fine, just suddenly decided it wants to go crazy! I tried @PandaRocks's solution. it did not work. I tried restarting stuff. even saw some stuff about a library file removal here.
finally ended up solving it by reinstalling the XGBoost using conda
as explained here:
$ conda install -c conda-forge xgboost
