Solving PyCharm bug: "Python helpers are not copied yet..."

I have been using PyCharm Professional to run and debug Python code from my Windows machine to a remote Linux device. There are some other tools available for the same purpose (e.g. Python Tool for Visual Studio 2017). But in my opinion, PyCharm Professional stands out among its counterparts as it comes with a "All Batteries Included" setup. Once you configure remote Python interpreter in PyCharm, then it works out of the box.

However, today after upgrading to PyCharm Professional 2018.2.1, I could not run my Python script on remote device. The execution always failed with below error -

"Error running 'hello': Python helpers are not copied yet to the remote host. Please wait until remote interpreter initialization finishes."

To solve this issue, I had to remove the ".pycharm_helpers" folder from the remove device and then restart PyCharm so that the folder is re-created and files are copied again.

Here are the steps with commands - 

1. Connect to the remote device using ssh 

    ssh <user_name>@<device_ip>

2. Run the below commands (In my case, ".pycharm_helpers" folder was created in remote Linux  device under "/home/root/" path)

    cd /home/root/

    cd ./.pycharm_helpers/

    rm -rf check_all_test_suite.py

    tar -xvzf helpers.tar.gz

3. Restart PyCharm and wait a little bit for the progress bar at bottom right to complete.
