When I try to run the following in the /riscv-tests/debug directory
it fails.
./gdbserver.py --spike64 --cmd ../../bin/spike
Traceback (most recent call last):

I have searched the entire RISCV installation for "pexpect.py" with no success. I installed the complete RISCV toolchain. I can build code and run
the ISA simulator using spike and pk.
Looks like the problem is with my python installation. I found 'python-pexpect' in my Linux package manager and installed. But I am now having errors with other python system libraries.

I am trying to use awkward in my Windows 10 system. I am using python 3.8.2.
After installing the package, when I import it, I am getting this DLL import error.
>>> import awkward as ak
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\MSS\Work\PyWorkspace37\awkward_poc\venv\lib\site-packages\awkward\__init__.py", line 23, in <module>

from awkward._ext import Index8
ImportError: DLL load failed while importing _ext: The specified module could not be found.
How to know which DLL is missing and how to mitigate it?
The DLL is Awkward Array's C++ part, "awkward/_ext.pyc", which the installation should have put into place. I see two possibilities: (1) the installation went horribly wrong and should be restarted from a clean slate, or (2) the file is there but can't be loaded. If the directory it was installed to doesn't have executable permissions, that could be it. (Python code can be executed from a disk/directory without executable permissions, but native machine code can't be, which can cause some surprises.)
When it comes to installation issues, I can only make guesses because your system is different than mine. We try to use standard installation procedures, so if you use the standard Python inhalation tools (pip, conda) then it ought to work without problems, but evidently that didn't happen here.
I got a new m1 MacBook Pro and installed the TensorFlow 2 provided by Apple, and I decided to do some testing for the MacBook, so I installed the python3 package "AIBenchmark", and the process was successful without any error messages. However, when I imported it, the following error message appeared.
Traceback (most recent call last):

How do I solve this problem?
I'm guessing that since AI Benchmark has not been updated since Dec. 18, 2019, the library is an Intel architecture binary. I don't know the details of the python 3.8 installation via the Xcode Command Line Tools, but I imagine it's a universal binary (both Intel and Apple Arm64 architecture). My guess is that you'll have to run TensorFlow as an Intel binary, so I would try the following in the terminal: precede your command to startup your app with
arch -x86_64
Or, configure Terminal to run under Rosetta2.
Right-click on Terminal in Finder
Get Info
Open with Rosetta
More suggestions here (no, it's not python or TensorFlow related, but yes, it's relevant).
getting up to speed on Anaconda, I keep receiving an error message when I try to import 'numpy' into Python.
Here is what I have done so far:
Downloaded anaconda from anaconda.com (64-Bit Graphical
Installer (466 MB) with Python 3.7 for Windows);
Installed anaconda (under C:\Users\'Username'\Anaconda3 | Option 'Register Anaconda3 as my default Python 3.7')
Now I'm trying to import numpy into Python using idle.exe, which produces following error message:
Warning: os.path.expanduser("~") points to
h:\,
but the path does not exist.
Futhermore, after executing "'import 'numpy;" in IDLE I get the following error message.
Unfortunately none of the advice was helpful. Numpy seems to be properly installed.

packages\numpy\__init__.py", line 140

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.7 from
"C:\Users\'Username'\Anaconda3\python.exe",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.18.1" you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
- If you're working with a numpy git repository, try `git clean -xdf`
(removes all files not under version control) and rebuild numpy.
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was: DLL load failed: The specified module could not be found.
Many thanks in advance for any help and suggestions.
I've been searching for it but could not find anything on the net on this topic.
When I'm working on a programm in python 3.5 which imports tkinter or pyglet I'm perfectly able to start it from the command line on my Linux Mint installation. As soon as I try to start it from pycharm or Visual Studio Code I get an error.
It is for tkinter:
Traceback (most recent call last): File "/home/b...", line 3, in <module>
import tkinter as tk
File "/usr/lib/python3.5/tkinter/__init__.py", line 35, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ImportError: No module named '_tkinter'
Both, the tkinter and the pyglet script, are working when they are started from idle3 (with F5).
Can anyone help me out?

i'm having the same issue. The problem lie with Linux Mint Software Manager. If your vs code is install via Software Manager, it will be install in Flatpak virtual sandbox. Just download and run vs code from its homepage will do.
While installing pyqt in windows 7 gives error:
D:\pyqt>python configure.py install
Traceback (most recent call last):
File "configure.py", line 32, in
import sipconfig
ImportError: No module named sipconfig
How to rectify this ?
It appears you are trying to build PyQt from source. Before you can do that, you must build and install SIP (clearly stated on the PyQt4 and PyQt5 download page)
You can obtain the SIP source code from riverbank computing (see here). You will then need to build SIP before you can build PyQt.
Note, since you are on windows, you probably dno't need to do any of this building, and can just install from the precompiled installers which are available on the download pages I linked to above.
