What is the correct observation shape for a 15x15 np array in a openai gym environment? - openai-gym

I am creating a gym enviroment which has a observation of just a 15x15 grid. The grid is filled initially with 0s, and as the game progresses the contents change to between 0 and 255. There are 225 possible actions, each of which corresponding to a location. My current code for init is:
self.action_space = Discrete(225)
self.observation_shape = Box(low=-1000,high=10000,shape=(15,15,),dtype=np.uint8)
however when running stable stable baselines 3 code:
import stable_baselines3
from stable_baselines3 import DQN
model = DQN("MultiInputPolicy", env, verbose=1)
model.learn(total_timesteps=10000, log_interval=4)
I get the error

This leads me to think that i have used the wrong openai gym space, or have defined shape() within box incorrectly. What would be the correct way to define a 15x15 numpy array?
Also, if it is useful, the context of the error message is
if isinstance(observation_space, spaces.Box):
return observation_space.shape
elif isinstance(observation_space, spaces.Discrete):
# Observation is an int
return (1,)
elif isinstance(observation_space, spaces.MultiDiscrete):
# Number of discrete features
return (int(len(observation_space.nvec)),)
elif isinstance(observation_space, spaces.MultiBinary):
# Number of binary features
return (int(observation_space.n),)
elif isinstance(observation_space, spaces.Dict):
return {key: get_obs_shape(subspace) for (key, subspace) in observation_space.spaces.items()}
else:
raise NotImplementedError(f"{observation_space} observation space is not supported")
Edit I couldn't find any solution to this, so i tried to use Keras-rl2 instead. With Keras-rl2, i ended up using (1,15,15) instead of (15,15,), but I don't know if that will work in Stable Baselines 2.

Parse .log file to collect data after keyword then create a nested dictionary using predefined column names

I am trying to parse a .log file using python for the Status information about processes of a linux system. The .log file has a lot of different sections of information, the sections of interest start with "##START-ALLPROCESSES-xxxxxxxx" where x is the epoch date and end with '##END-ALLPROCESSES-xxxxxxx". After this line each process is listed with 52 columns each, the number of processes may change depending on the info recorded at the time, and there may be multiple sections with this information at different times.
The idea is to open the .log file, find the sections and then use the XXXXXXX as the key for a nested dictionary where the keys are the predefined column dates filled in with the values from the section, and do this for all different sections that would be found on the .log fie. The nested dictionary would look something like below
[date1-XXXXXX:
[ columnName1: process1,
.
.
.
columnName52: info1
],
.
.
.
[ columnName1: process52,
.
.
.
columName52: info52
]
],
[date2-XXXXXX:
[ columnName1: process1,
.
.
.
columnName52: info1
],
.
.
.
[ columnName1: process52,
.
.
.
columName52: info52
]
]
The data in the .log file looks as follow and would have multiple sections as this but with a different date each line starts with the process id and (process name)

data_dict[data[i][0]] = {}
for j in range(len(columns)):
data_dict[data[i][0]][columns[j]] = data[i][j+1]
print(data_dict)
I converted the epoch date into a str as I was getting unhashable list errors, however that made it so the epoch date shows as a key but each column now has the entire list for the 52 columms of information as a single one, so definitely I am missing something
To solve this problem, you could follow the following steps:
Open the .log file and read the contents
Search for all the sections of interest by finding lines that start with "##START-ALLPROCESSES-" and end with "##END-ALLPROCESSES-"
For each section found, extract the epoch date and create a dictionary with an empty list for each of the 52 columns
Iterate over the lines within the section and split the line into the 52 columns using space as a separator. Add the values to the corresponding list in the dictionary created in step 3
Repeat steps 3 and 4 for all the sections found in the .log file
Return the final nested dictionary
Here is some sample code that implements these steps:
import re
def parse_log_file(log_file_path):
with open(log_file_path, 'r') as log_file:
log_contents = log_file.read()
sections = re.findall(r'##START-ALLPROCESSES-(.*?)##END-ALLPROCESSES-', log_contents, re.DOTALL)
nested_dict = {}
for section in sections:
lines = section.strip().split('\n')
epoch_date = lines[0].split('-')[-1]
column_names = ['column{}'.format(i) for i in range(1, 53)]
section_dict = {column_name: [] for column_name in column_names}
for line in lines[1:]:
values = line.strip().split()
for i, value in enumerate(values):
section_dict[column_names[i]].append(value)
nested_dict['date{}-{}'.format(epoch_date, len(section_dict['column1']))] = section_dict
return nested_dict
You can call this function by passing the path to the .log file as an argument. The function returns the nested dictionary described in the problem statement.

How can I print a '/' at a specific index in my matrix in python

I am expecting an output that prints a '/' at an index position of matrix[5][5] like below-

0 0 0 0 0 0 0 0 0 0
The code I wrote is-
R = 10 #int(input("Enter the number of rows:"))
C = 10 #int(input("Enter the number of columns:"))
# Initialize matrix
matrix = []
print("Enter the entries rowwise:")
# For user input
for i in range(R): # A for loop for row entries
a =[]
for j in range(C): # A for loop for column entries
a.append(0)
matrix.append(a)
#print("/",matrix[index[20]][index[10]])
#matrix.insert([0][0],'/')
for i in range(R):
for j in range(C):
print(matrix[i][j], end = " ")
print()
I tried-
matrix.insert([0][0],'/')
But this caused an error as-
shubham#IAMSB:~$ python3 final.py
Enter the entries rowwise:
/ Traceback (most recent call last):

Please forgive my mistakes I new to PYTHON
Thanks in Advance!
Simplest is you can have an if condition when you are populating the list.

Create dummy variables for interdependent categories in pandas

I'm trying to set up a linear regression model in order to predict traffic counts based on the day, and the time of day. Since both are categorical variables, I have to create dummy variables. The get_dummies function makes this very easy, when doing this for both variables individually. However, in the case of predicting traffic volumes, the interdependence between the day and the time of day are important. Therefore, I'll need dummies for all days * all time intervals.
I made a small example, avoiding to trouble you with big datasets:
import pandas as pd
df = pd.DataFrame({'Day': ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],
'Time': [11,15,9,15,17,10,20],
'Count': [100,150,150,150,180,60,50]})
df_dummies = pd.get_dummies(df.Day)
print(df_dummies)
Results in a nice dataframe with dummies:
Fri Mon Sat Sun Thu Tue Wed
0 0 1 0 0 0 0 0
1 0 0 0 0 0 1 0
2 0 0 0 0 0 0 1
3 0 0 0 0 1 0 0
4 1 0 0 0 0 0 0
5 0 0 1 0 0 0 0
6 0 0 0 1 0 0 0
So what I'm after is something like this:
import pandas as pd
df = pd.DataFrame({'Day': ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],
'Time': [11,15,9,15,17,10,20],
'Count': [100,150,150,150,180,60,50]})
df_dummies = pd.get_dummies(df.Day * df.Time)
print(df_dummies)
With a result like this:
Fri_9 Fri_15 Mon_9 Mon_15 Sat_9 Sat_15 Sun_9 ...
0 0 1 0 0 0 0 0 ...
1 0 0 0 0 0 1 0 ...
2 0 0 0 0 0 0 1 ...
3 0 0 0 0 1 0 0 ...
4 1 0 0 0 0 0 0 ...
5 0 0 1 0 0 0 0 ...
6 0 0 0 1 0 0 0 ...
7 0 0 0 0 0 0 0 ...
[...]
Is there any way in which this can be done elegantly?
I belive need join columns together with cast to strings:
df_dummies = pd.get_dummies(df.Day + '_' + df.Time.astype(str))
#df_dummies = pd.get_dummies(df.Day.str.cat(df.Time.astype(str), sep='_'))
print(df_dummies)
Fri_17 Mon_11 Sat_10 Sun_20 Thu_15 Tue_15 Wed_9
0 0 1 0 0 0 0 0
1 0 0 0 0 0 1 0
2 0 0 0 0 0 0 1
3 0 0 0 0 1 0 0
4 1 0 0 0 0 0 0
5 0 0 1 0 0 0 0
6 0 0 0 1 0 0 0
I'm trying to set up a linear regression model in order to predict
Technically, you can make a dummy of the tuples:
>>> pd.get_dummies(df[['Day', 'Time']].apply(tuple, axis=1))
(Fri, 17) (Mon, 11) (Sat, 10) (Sun, 20) (Thu, 15) (Tue, 15) (Wed, 9)
0 0 1 0 0 0 0 0
1 0 0 0 0 0 1 0
2 0 0 0 0 0 0 1
3 0 0 0 0 1 0 0
4 1 0 0 0 0 0 0
5 0 0 1 0 0 0 0
6 0 0 0 1 0 0 0
...
however, I think this approach is not the best at the ML level. This will probably fragment the data very much, making things hard for your regressor. You might consider using a gradient-boosted decision tree, if you're after the interactions.

Rare error while computing dataframe by using pandas

I am dealing a rare error while making some machine learning with a dataset loaded using pandas.
This is the error I am getting:
I have been reading something releated to it and it seems to be due to the columns and how pandas interpret them but I have no clue what can be wrong.

Thanks in advance
In clf.fit method, according to the document parameters expected are array:
Parameters
----------
X : array-like, shape (n_samples, n_features)
Training data.
y : array, shape (n_samples,)
If you look at the example in link X and y are numpy array:
Try using as_matrix() for both X and y instead of just X = pima[feature_cols] and y = pima.label
X = pima[feature_cols].as_matrix()
y = pima.label.as_matrix()
Testing by print:
import pandas as pd
url = 'https://archive.ics.uci.edu/ml/machine-learning-databases/pima-indians-diabetes/pima-indians-diabetes.data'
col_names = ['pregnant', 'glucose', 'bp', 'skin', 'insulin', 'bmi', 'pedigree', 'age', 'label']
pima = pd.read_csv(url, header=None, names=col_names)
# define X and y
feature_cols = ['pregnant', 'glucose', 'bp', 'skin', 'insulin', 'bmi', 'pedigree', 'age']
X = pima[feature_cols].as_matrix()
y = pima.label.as_matrix()
#k fold cv

Score on testing set - Text mining

I try to print accurancy score after score validation. Score validation is equal to 82%. But the accuracy score is equal to 0 ...
grid = GridSearchCV(pipe, param_grid, cv=5)
grille=grid.fit(text_train, Y_train)
y_pred = grille.predict(text_test)
from sklearn import metrics
#matrice de confusion
print("matrice confusion")
print(metrics.confusion_matrix(Y_test,y_pred))
#succès en test
print("score accuracy")
print(metrics.accuracy_score(Y_test,y_pred))
When I print confusion matrix :
[[ 0 0 0 0 0 0 0 0 0 0 27 2]
[ 0 0 0 0 0 0 0 0 0 0 88 23]
[ 0 0 0 0 0 0 0 0 0 0 12 0]
[ 0 0 0 0 0 0 0 0 0 0 22 4]
[ 0 0 0 0 0 0 0 0 0 0 108 90]
[ 0 0 0 0 0 0 0 0 0 0 28 60]
[ 0 0 0 0 0 0 0 0 0 0 16 94]
[ 0 0 0 0 0 0 0 0 0 0 49 424]
[ 0 0 0 0 0 0 0 0 0 0 5 76]
[ 0 0 0 0 0 0 0 0 0 0 78 1487]
[ 0 0 0 0 0 0 0 0 0 0 0 0]
[ 0 0 0 0 0 0 0 0 0 0 0 0]]
I don't understand why.. and what is the format of my matrix (0 0 0 0 0 0 0 27)
Here is documentation for confusion and accuracy.
Very simply, the confusion matrix claims that all of the validation inputs were in classes 0-9, but incorrectly identified as class 10 or 11.
Since you failed to provide the canonical Minimal, complete, verifiable example, I have no way to work on the problem past this point. Please update this with code that reproduces the problem.
