Creating DataFrames in Python or IPython consoles make Spyder 2.3.6 to hang

[mshashanka]

This is similar to #2652.

I just upgraded to spyder 2.3.6. I am using pandas 0.16.2 and IPython 4.0 on OS X Yosemite. Spyder essentially crashes (it hangs and I have to force quit the application) when I try to run a code snippet like the one below in the spyder ipython console. The same code works just fine if I open ipython in a terminal window and run it.

import pandas as pd
df = pd.read_csv('csv_file.csv')
tmp = df.groupby(['field1', 'field2']).agg( {'field3':['sum'], 'field4':['sum']})

Thanks for reporting. I'll try to fix it ASAP.

Question: was this working for you in Spyder 2.3.5.2?

[mshashanka]

Thanks! Yes, it works fine in 2.3.5.2, that's what I'm using now.

Am also running spyder 2.3.6 w/ pandas 0.16.2 and ipython 4.0.1 on OS X Yosemite and have the same issue when using the pandas pivot function. This can be avoided by shutting variable explorer panel.

[ccordoba12]

@msweier, this error will be fixed in 2.3.7. Sorry for the inconvenience :-)

[msweier]

No problem thanks!

[d1manson]

I'm having the same issue, even just doing x = pd.DataFrame(np.ones(10)) causes a crash when the variable explorer is open.
..a quick dig around in variable explorer code didn't seem to reveal much - it's quite complicated down there!

[ccordoba12]

Just for the record: this happens only in Python 2. Python 3 seems immune to this bug :-)

[ccordoba12]

This was caused by trying to fix issue #2514.

[stonebig]

thanks ! would it be possible to have an earlier 2.3.7 with this important fix ?

[ccordoba12]

@stonebig, yes, of course. That's why I tagged this issue with the 2.3.7 milestone. I hope to release it this weekend :-)

[vrajs5]

I think problem is still not resolved with 2.3.7 with following other packages

    ipython:   4.0.0-py27_0
    jedi:      0.9.0-py27_0  
    qtconsole: 4.1.0-py27_0
    alabaster: 0.7.3-py27_0
    sphinx:     1.3.1-py27_0
    spyder:    2.3.7-py27_1

[stonebig]

you may try to downgrade to Jedi 0.8.1.

[vrajs5]

@stonebig - nope jedi downgrade didn't work out...

ok, so today, with spyder git of October 14th:

• at first start of spyder qtconsole failed (not sure why, maybe a timeout)

[sean-violante-lendico]

@vrajs5, there is a separate bug fro empty dataframes! have you tried that fix
#2744

[stonebig]

no issue whatsoever with spyder3.0dev of yesterday night, even on Python 2.7.
