What steps will reproduce the problem?

1. Install newest version of Anaconda (Python 3.6).

3. pip install telegram_send
4. Start spyder and import telegram_send

Traceback (most recent call last):
  File "<ipython-input-1-4a435a0249ac>", line 1, in <module>
    import telegram_send
  File "C:\Anaconda3\lib\site-packages\telegram_send.py", line 28, in <module>

    fp, pathname, (ext,mode,ty) = imp.find_module(fullname,package_path)

  File "C:\Anaconda3\lib\imp.py", line 270, in find_module
    "not {}".format(type(path)))

RuntimeError: 'path' must be None or a list, not <class '_frozen_importlib_external._NamespacePath'>

This works fine in the regular python or iPython console.

There's not a single line related to Spyder code in your error report. Sorry, but I fail to see how this can be solved in our side.

[skjerns]

But why does this error only appear when using Spyder and not within a regular iPython console?

[ccordoba12]

I really don't know, but unfortunately we don't have time to help you to debug this.

I have a similar issue with the pyART library. @skjerns : did you solve your problem? If yes, how?

[ccordoba12]

This is a duplicate of issue #5299. There's a workaround in that issue that you need to apply before we solve it for good.

I have same problem when I import tensorflow.contrib.slim as slim with spyder, but it is ok in Jupyter or cmd window. How can I solve it? @ccordoba12 Did you solve your problem? @jegehrin @skjerns

This is a duplicate of issue #5299. Please see that issue for a temporary fix.

For the anaconda users out there, I found my sitecustomize.py file with the following command...
find ~/anaconda3 -name 'sitecustomize.py'
I then quit and restarted both Anaconda and Spyder and it worked.
PS. Long live Spyder!!
