Try the following lines of codes:
em = cv2.ml.EM_create()
em.setClustersNumber(N)
em.trainEM(descriptors)

im new into this new languaje named python and im trying to use matplotlib
here my code :
import matplotlib.pyplot as plt
plt.plot([1, 2, 3, 4])
plt.ylabel('some numbers')
plt.show()

XGBoost error 'DMatrix' object does not support indexing

I am trying to use XGBoost library using .train function and DMatrix but I am a little stuck because of an error :

TypeError: 'DMatrix' object does not support indexing
Here my piece of code :
dtrain = xgb.DMatrix(X_data[train_idx], label=np.log1p(y_data[train_idx])) # datas.slice(train_idx)
dtest = xgb.DMatrix(X_data[val_idx], label=np.log1p(y_data[val_idx]))
print('data created for xgboost')
model = self.model_base.train(params=params, dtrain=dtrain, num_boost_round=number_iteration, evals=[dtest], early_stopping_rounds=early_stopping_rounds)
Does anyone know how to solve the problem ?

The problem is with the evals argument. A list of tuples is expected, so change evals=[dtest] to evals=[(dtest, "Test")].

Getting NotImplementedError when using data from dask when running an OLS regression

What I want to do is actually pretty simple. I want to run a OLS regression by using data from dask. It is fine, if I just install data into dask dataframe or I use pandas (but I get memory error when I use Pandas).
# import modules
import statsmodels.formula.api as smf
import dask.dataframe as dd
df = dd.read_csv(input_file)
mod = smf.ols(formula='lnq ~ lnp + lnp:C(product_code)+ C(product_code)', data=df)
results = mod.fit(cov_type = 'cluster', cov_kwds={'groups': df['product_code']})
print(results.summary())
However, I get the following error:

Any ideas?

I don't believe that statsmodels offers support for dask dataframes

Because other code runs well, it seems theano.function induced the problem. Although I tried use In() to add test value to coefficients and x, the problem also stand there.

Ok, I have found a similar question on the official site Creating a step-function: Optimization failure due to: local_subtensor_merge. It may be caused by Pymc3 default settings. There they gave several ways. I use test values as noted in the last comment and set
theano.config.compute_test_value = "warn"
the errors are removed.

Python wired index out of bound

I was trying to create a volume weighted average price using python.
Here is my code:
vwap = []
for i in range(window, int(price_times_qty)):
vol_total = 0
vol_price = 0
for j in range(window):
vol_total = vol_total + lastqty[i-j]
vol_price = vol_price + lastqty[i-j] * lastprice[i-j]
vwap.append( vol_price / vol_total )
I believe my idea is right, but when I execute the code, I have the error:
Traceback (most recent call last):
File "<ipython-input-9-9724942aa7be>", line 1, in <module>
runfile('/home/intern2/Desktop/VWAP/vwap-v1.py', wdir='/home/intern2/Desktop/VWAP')

vol_total = vol_total + lastqty[i-j]
IndexError: index out of bounds
I just have no idea why the error is index out of bound. When I check my code, I think the index is well within the bound.
Could anyone please help me with it?
