conda virtual environment not working with pycharm

Question

i have a script gapminder1.py which uses the panda and sklern.

# TODO: Add import statements

import pandas as pd

from sklearn.linear_model import LinearRegression


# Assign the dataframe to this variable.
# TODO: Load the data
bmi_life_data = pd.read_csv("CSV_DATA/bmi_and_life_expectancy.csv")
print(bmi_life_data)
# Make and fit the linear regression model
#TODO: Fit the model and Assign it to bmi_life_model
bmi_life_model = LinearRegression()
bmi_life_model.fit(bmi_life_data[['BMI']], bmi_life_data[['Life expectancy']])
# Make a prediction using the model
# TODO: Predict life expectancy for a BMI value of 21.07931
laos_life_exp = bmi_life_model.predict(21.07931)

i am running the script from cmd console which is working fine but the same script from pycharm showing me the error

C:\Users\tripathi\AppData\Local\Continuum\anaconda3\envs\dsnd\python.exe C:/Users/tripathi/PycharmProjects/dsnd/gapminder1.py
Traceback (most recent call last):
  File "C:/Users/tripathi/PycharmProjects/dsnd/gapminder1.py", line 3, in <module>
    import pandas as pd
  File "C:\Users\tripathi\AppData\Local\Continuum\anaconda3\envs\dsnd\lib\site-packages\pandas\__init__.py", line 19, in <module>
    "Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']

i am using same conda environment on both the places but not sure why it is not working fine.

Answer 1

This is a known issue in PyCharm on Windows at least. The conda environment is used but not actually activated by PyCharm so environment variables for the env are not loaded. It's been a problem for a while, seems it'd be easy to fix but for some reason they haven't fixed it.

The only work around is to start PyCharm from a cmd window in which the env is activated, or possibly run the environment activation prior to execution as an external tool.

Answer 2

Okay, I think it's an issue where Conda and pycharm are not communicating with each other properly. This is the reason why I always create my virtual environment using PyCharm.

Option 1: Create a new virtual environment using PyCharm

Try the instructions by jetbrains.

Option 2: Delete and reconnect to your old Conda environment and check the settings

Perhaps you didn't check some of the boxes when connecting to the environment via PyCharm:

• Inherit global site-packages
• Make available to all projects

Answer 3

You have to install numpy into the conda virtual environment using pycharm settings.

1. Go to Settings->Project->Project Interpreter
2. Click the green plus mark(Install) as shown below.

3. Search and select numpy from the available packages list and click install package.

Answer 4

Make sure you have pip installed numpy, also check on the paths at environment variables at My Computer or Control Panel.

Answer 5

Method 1

Try uninstaling and again installing pandas and numpy by:

conda uninstall pandas
conda uninstall numpy
conda install pandas
conda install numpy

You have to do this using the same python(conda) environment which is in the question

Method 2

Try deleting all .pyc files in the project directory

Method 3

Try importing numpy in your gapminder1.py by adding a import numpy line at the top

You might need to use multiple methods. Follow the solution according to the given order.

Hope it helps. Thanks and regards
