• Extension version (available under the Extensions sidebar): 2019.6.24221
• Python version (& distribution if applicable, e.g. Anaconda): conda 4.7.10, Python 3.7.3
• Type of virtual environment used: (N/A | venv | virtualenv | conda | ...): None
• Relevant/affected Python packages and their versions: matplotlib matplotlib-3.1.0-py37hc8f65d3_0.conda
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info How to update the language server to the latest stable version #3977): XXX

Run under default python debug configuration:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Python: Current File",
      "type": "python",
      "request": "launch",
      "program": "${file}",
      "console": "integratedTerminal"
    }
  ]
}

As recommended, using cmd.exe as integrated shell in user settings.json:

    "terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\cmd.exe"

Simple test_import_mplot3d.py:

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
fig = plt.figure()
my_plot = fig.gca(projection='3d')

Expected behaviour

Debug test_import_mplot3d.py and run to completion without error

Actual behaviour

Debug console traceback:

Thanks for reporting this issue. Please could you provide a screenshot of the text sent to the terminal (I'd like to check whether the conda environment got activated before the debugger command was sent to the terminal).

I totally forgot to mention that it does actually succeed on the second time, since it seems to re-use the terminal, which now seems to have the default anaconda environment successfully enabled.

Here is the full terminal output from the both runs, using the test python script posted before:
