I have this code in Spyder (Python 3.7):
import numpy as np
import matplotlib.pyplot as plt
#%% Práctica 1
%reset -f
plt.close("all")
If I only run one of the commands (any of them) works well, but I can't run both of them at the same time (Then, I get the error name 'plt' is not defined althought I have run the import command). I don't have any clue about what can happen.
I hope someone can help me. Thank you for your answers.
Change the order of commands:
%reset -f
import numpy as np
import matplotlib.pyplot as plt
plt.close("all")

I am trying to run a python code using VS code, I noticed that the result is different from the local terminal.
here is the code:
import tensorflow as tf
from tensorflow import keras
import os
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
os.environ['TF_CPP_MIN_LOG_LEVEL']='2'
a=tf.constant(10)
print(f"a = {a}")
its successfully running using my local terminal and I am having the error below while using my vs code terminal.
File "00-test.py", line 11
print(f"a = {a}")
^```
you can check if the two pythons in vscode terminal and local terminal have the same version,or with the same enviro
I am trying to import Image from PILLOW.
from PILLOW import Image
im = Image.open("bride.jpg")
im.rotate(45).show()
Undefined function 'from' for input arguments of type 'char'.
>> import PIL.Image
im = Image.open("bride.jpg")
im.rotate(45).show()
Error using import
Import argument 'PIL.Image' cannot be found or cannot be imported.
Undefined function 'from' for input arguments of type 'char'.
I keep getting the same error. Am I using the wrong import statement?
EDIT:
I noticed something else. when i browse through my C:/ drive and look inside the folders where Pip, and PIL ,etc is. There is nothing inside them. Even when i copy a file with stuff to that area, and open that new file, i cant see any of the stuff inside. When i copy it though, and the green bar goes it shows data being transferred.
The Code:

Example:
enter code here
from PIL import Image, ImageEnhance

%matplotlib inline
import matplotlib
from matplotlib import animation, rc
import matplotlib.pyplot as plt
from matplotlib.pyplot import imshow
from IPython.display import HTML

The reason your binder doesn't work is because your requirements.txt looks like this:
matplotlib==2.0.2
requests==2.20.0
Pillow==5.0.0
numpy==1.13.0
scipy==0.19.0
pandas==0.20.2
scikit-learn==0.18.1
tzlocal-1.5.1
This line:
tzlocal-1.5.1
Probably breaks the binder dependency install. Another thing is that these are very specific versions that might generate too specific dependencies (ref. here). I recommend changing it to this:
matplotlib
requests
pillow
numpy
scipy
pandas
scikit-learn
tzlocal
At least your binder started working when I did that.
Locally you will just have to run pip install -r requirements.txt with an admin command prompt and then your local Jupyter installation should automatically work, at least it did when I cloned your notebook to a Windows VM.
When I run the following code in PyCharm on a Mac:
import numpy as np
import pandas as pd
from subprocess import check_output
print(check_output(["ls", "../input"]).decode("utf8"))
import time
import copy
import numpy as np
import pandas as pd
import chainer
import chainer.functions as F
import chainer.links as L
from plotly import tools
from plotly.graph_objs import *
from plotly.offline import init_notebook_mode, iplot, iplot_mpl
init_notebook_mode()
data = pd.read_csv('../input/Data/Stocks/goog.us.txt')
data['Date'] = pd.to_datetime(data['Date'])
data = data.set_index('Date')
print(data.index.min(), data.index.max())
data.head()
There were some errors:

vecLib, which is a part of Accelerate, is known not to work correctly with Chainer.
We recommend using other BLAS libraries such as OpenBLAS.

I'm new in Chainer and DQN. Could anyone help me edit this code to make it work? Thank you so much!
It seems like you're trying to run plotly interactive functions (i prefix) in a normal Python code (i.e. not IPython Notebook). iplot provides an interactive graph with which you can play inside the notebook.
I'd start with removing iplot import and replacing it with normal plot. Also, remove iplot_mpl and init_notebook_mode from your imports.
You can install 'ipython' in the virtual environment and then try running it directly from the terminal.
Activate the virtual environment
pip3 install ipython
python3 prog.py
Worked in my case.
I have the following python code:
import tensorflow as tf
import numpy as np
import math
import matplotlib.pyplot as plt
import matplotlib.animation as animation
num_house = 160
np.random.seed(42)
house_size = np.random.randint(low=1000, high=3500, size=num_house)
I am trying to debug this python code in visual studio code. I have selected the right configuration (Python: Current File (Integrated Terminal)). I have set my breakpoint on the last line. When i run from the debug console, my code fails giving me a ModuleNotFoundError. But I am able to execute this program in the terminal. How do I debug this code in vs code?
When I create a new IPython notebook it opens a blank notebook. I would like instead that all my notebooks open with a few cells already populated with stuff that I always use. For example, the first cell would have some magic commands
%load_ext autoreload
%autoreload 2
%matplotlib inline
The second cell might contain some standard imports
import numpy as np
import matplotlib as mpl
from matplotlib import pyplot as plt
from matplotlib.collections import PatchCollection
from netCDF4 import Dataset
from tabulate import tabulate
Is it possible to tell IPython somewhere how to template new files so that this can be done?
You could set up a configuration file for ipython as described here. For example run:
ipython profile create
to create a default ipython profile (probably with the name ${HOME}/.ipython/profile_default/ipython_config.py directory) (or you could just create this file yourself). You could then edit this to include e.g.:
c = get_config()
c.InteractiveShellApp.exec_lines = [
'%load_ext autoreload',
'%autoreloud 2',
'%matplotlib inline',
'import numpy as np',
'import matplotlib as mpl',
'from matplotlib import pyplot as plt',
'from matplotlib.collections import PatchCollection',
'from netCDF4 import Dataset',
'from tabulate import tabulate'
]
However, this just runs commands in the background before your notebook ipython session starts and doesn't actually populate the first cell.
